Airflow Breeze is an easy-to-use development and test environment using Docker Compose. The environment is available for local use and is also used in Airflow's CI tests.
We called it Airflow Breeze as It's a Breeze to contribute to Airflow.
The advantages and disadvantages of using the Breeze environment vs. other ways of testing Airflow are described in CONTRIBUTING.rst.
All the output from the last ./breeze command is automatically logged to the logs/breeze.out
file.
Watch the video below about Airflow Breeze. It explains the motivation for Breeze and screencasts all its uses.
- Version: Install the latest stable Docker Community Edition and add it to the PATH.
- Permissions: Configure to run the
docker
commands directly and not only via root user. Your user should be in thedocker
group. See Docker installation guide for details. - Disk space: On macOS, increase your available disk space before starting to work with the environment. At least 128 GB of free disk space is recommended. You can also get by with a smaller space but make sure to clean up the Docker disk space periodically. See also Docker for Mac - Space for details on increasing disk space available for Docker on Mac.
- Docker problems: Sometimes it is not obvious that space is an issue when you run into
a problem with Docker. If you see a weird behaviour, try
breeze cleanup-image
command. Also see pruning instructions from Docker.
Here is an example configuration with more than 200GB disk space for Docker:
- Version: Install the latest stable Docker Compose and add it to the PATH. See Docker Compose Installation Guide for details.
- Permissions: Configure permission to run the
docker-compose
command.
- WSL 2 installation :
- Install WSL 2 and a Linux Distro (e.g. Ubuntu) see WSL 2 Installation Guide for details.
- Docker Desktop installation :
- Install Docker Desktop for Windows. For Windows Home follow the Docker Windows Home Installation Guide. For Windows Pro, Enterprise, or Education follow the Docker Windows Installation Guide.
- Docker setting :
- WSL integration needs to be enabled
- WSL 2 Filesystem Performance :
Accessing the host Windows filesystem incurs a performance penalty, it is therefore recommended to do development on the Linux filesystem. E.g. Run
cd ~
and create a development folder in your Linux distro home and git pull the Airflow repo there.
- WSL 2 Memory Usage :
WSL 2 can consume a lot of memory under the process name "Vmmem". To reclaim the memory after development you can:
- On the Linux distro clear cached memory:
sudo sysctl -w vm.drop_caches=3
- If no longer using Docker you can quit Docker Desktop (right click system try icon and select "Quit Docker Desktop")
- If no longer using WSL you can shut it down on the Windows Host
with the following command:
wsl --shutdown
- On the Linux distro clear cached memory:
- Developing in WSL 2 :
You can use all the standard Linux command line utilities to develop on WSL 2. Further VS Code supports developing in Windows but remotely executing in WSL. If VS Code is installed on the Windows host system then in the WSL Linux Distro you can run
code .
in the root directory of you Airflow repo to launch VS Code.
For Linux, run
apt install util-linux coreutils
or an equivalent if your system is not Debian-based.For macOS, install GNU
getopt
andgstat
utilities to get Airflow Breeze running.Run
brew install gnu-getopt coreutils
and then follow instructions to link the gnu-getopt version to become the first on the PATH. Make sure to re-login after you make the suggested changes.
Examples:
If you use bash, run this command and re-login:
echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> ~/.bash_profile
. ~/.bash_profile
If you use zsh, run this command and re-login:
echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> ~/.zprofile
. ~/.zprofile
Let's confirm that getopt
and gstat
utilities are successfully installed
$ getopt --version
getopt from util-linux *
$ gstat --version
stat (GNU coreutils) *

Minimum 4GB RAM for Docker Engine is required to run the full Breeze environment.
On macOS, 2GB of RAM are available for your Docker containers by default, but more memory is recommended (4GB should be comfortable). For details see Docker for Mac - Advanced tab.
On Windows WSL 2 expect the Linux Distro and Docker containers to use 7 - 8 GB of RAM.
Minimum 40GB free disk space is required for your Docker Containers.
On Mac OS This might deteriorate over time so you might need to increase it or run docker system --prune
periodically. For details see
Docker for Mac - Advanced tab.
On WSL2 you might want to increase your Virtual Hard Disk by following: Expanding the size of your WSL 2 Virtual Hard Disk
You may need to clean up your Docker environment occasionally. The images are quite big (1.5GB for both images needed for static code analysis and CI tests) and, if you often rebuild/update them, you may end up with some unused image data.
To clean up the Docker environment:
Stop Breeze with
./breeze stop
. (If Breeze is already running)Run the
docker system prune
command.Run
docker images --all
anddocker ps --all
to verify that your Docker is clean.Both commands should return an empty list of images and containers respectively.
If you run into disk space errors, consider pruning your Docker images with the docker system prune --all
command. You may need to restart the Docker Engine before running this command.
In case of disk space errors on macOS, increase the disk space available for Docker. See Prerequisites for details.
Installation is as easy as checking out Airflow repository and running Breeze command.
You enter the Breeze test environment by running the ./breeze
script. You can run it with
the help
command to see the list of available options. See Breeze Command-Line Interface Reference
for details.
./breeze
The First time you run Breeze, it pulls and builds a local version of Docker images. It pulls the latest Airflow CI images from Airflow DockerHub and uses them to build your local Docker images. Note that the first run (per python) might take up to 10 minutes on a fast connection to start. Subsequent runs should be much faster.
Once you enter the environment, you are dropped into bash shell of the Airflow container and you can run tests immediately.
To use the full potential of breeze you should set up autocomplete and you can
add the checked-out Airflow repository to your PATH to run Breeze without the ./
and from any directory.
The breeze
command comes with a built-in bash/zsh autocomplete setup command. After installing, when you
start typing the command, you can use <TAB> to show all the available switches and get
auto-completion on typical values of parameters that you can use.
You should set up the autocomplete option automatically by running:
./breeze setup-autocomplete
You get the auto-completion working when you re-enter the shell.
When you enter the Breeze environment, automatically an environment file is sourced from
files/airflow-breeze-config/variables.env
. The files
folder from your local sources is
automatically mounted to the container under /files
path and you can put there any files you want
to make available for the Breeze container.
You can also add your local tmux configuration in files/airflow-breeze-config/.tmux.conf
and
these configurations will be available for your tmux environment.
there is a symlink between files/airflow-breeze-config/.tmux.conf
and ~/.tmux.conf
in the container,
so you can change it at any place, and run
tmux source ~/.tmux.conf
inside container, to enable modified tmux configurations.
Breeze helps with running tests in the same environment/way as CI tests are run. You can run various types of tests while you enter Breeze CI interactive environment - this is described in detail in TESTING.rst
You can use additional breeze
flags to choose your environment. You can specify a Python
version to use, and backend (the meta-data database). Thanks to that, with Breeze, you can recreate the same
environments as we have in matrix builds in the CI.
For example, you can choose to run Python 3.6 tests with MySQL as backend and in the Docker environment as follows:
./breeze --python 3.6 --backend mysql
The choices you make are persisted in the ./.build/
cache directory so that next time when you use the
breeze
script, it could use the values that were used previously. This way you do not have to specify
them when you run the script. You can delete the .build/
directory in case you want to restore the
default settings.
The defaults when you run the Breeze environment are Python 3.6 version and SQLite database.
If you are having problems with the Breeze environment, try the steps below. After each step you can check whether your problem is fixed.
- If you are on macOS, check if you have enough disk space for Docker.
- Restart Breeze with
./breeze restart
. - Delete the
.build
directory and run./breeze build-image
. - Clean up Docker images via
breeze cleanup-image
command. - Restart your Docker Engine and try again.
- Restart your machine and try again.
- Re-install Docker CE and try again.
In case the problems are not solved, you can set the VERBOSE_COMMANDS variable to "true":
export VERBOSE_COMMANDS="true"
Then run the failed command, copy-and-paste the output from your terminal to the Airflow Slack #airflow-breeze channel and describe your problem.
Airflow Breeze is a bash script serving as a "swiss-army-knife" of Airflow testing. Under the hood it uses other scripts that you can also run manually if you have problem with running the Breeze environment.
Breeze script allows performing the following tasks:
Managing CI environment:
- Build CI docker image with
breeze build-image
command- Enter interactive shell in CI container when
shell
(or no command) is specified- Join running interactive shell with
breeze exec
command- Stop running interactive environment with
breeze stop
command- Restart running interactive environment with
breeze restart
command- Run test specified with
breeze tests
command- Generate constraints with
breeze generate-constraints
- Execute arbitrary command in the test environment with
breeze shell
command- Execute arbitrary docker-compose command with
breeze docker-compose
command- Push docker images with
breeze push-image
command (require committers rights to push images)
You can optionally reset the Airflow metadata database if specified as extra --db-reset
flag and for CI image
you can also start integrations (separate Docker images) if specified as extra --integration
flags. You can also
chose which backend database should be used with --backend
flag and python version with --python
flag.
You can also have breeze launch Airflow automatically breeze start-airflow
, this will drop you in a
tmux session with four panes:
- one to monitor the scheduler,
- one for the webserver,
- one monitors and compiles JavaScript files,
- one with a shell for additional commands.
Managing Prod environment (with --production-image
flag):
- Build CI docker image with
breeze build-image
command- Enter interactive shell in PROD container when
shell
(or no command) is specified- Join running interactive shell with
breeze exec
command- Stop running interactive environment with
breeze stop
command- Restart running interactive environment with
breeze restart
command- Execute arbitrary command in the test environment with
breeze shell
command- Execute arbitrary docker-compose command with
breeze docker-compose
command- Push docker images with
breeze push-image
command (require committers rights to push images)
You can optionally reset database if specified as extra --db-reset
flag. You can also
chose which backend database should be used with --backend
flag and python version with --python
flag.
Manage and Interact with Kubernetes tests environment:
- Manage KinD Kubernetes cluster and deploy Airflow to KinD cluster
breeze kind-cluster
commands- Run Kubernetes tests specified with
breeze kind-cluster tests
command- Enter the interactive kubernetes test environment with
breeze kind-cluster shell
command
Run static checks:
- Run static checks - either for currently staged change or for all files with
breeze static-check
command
Build documentation:
- Build documentation with
breeze build-docs
command
Set up local development environment:
- Setup local virtualenv with
breeze setup-virtualenv
command- Setup autocomplete for itself with
breeze setup-autocomplete
command
Breeze keeps data for all it's integration in named docker volumes. Each backend and integration
keeps data in their own volume. Those volumes are persisted until ./breeze stop
command or
./breeze restart
command is run. You can also preserve the volumes by adding flag
--preserve-volumes
when you run either of those commands. Then, next time when you start
Breeze
, it will have the data pre-populated. You can always delete the volumes by
running ./breeze stop
without the --preserve-volumes
flag.
Often if you want to run full airflow in the Breeze environment you need to launch multiple terminals and
run airflow webserver
, airflow scheduler
, airflow worker
in separate terminals.
This can be achieved either via tmux
or via exec-ing into the running container from the host. Tmux
is installed inside the container and you can launch it with tmux
command. Tmux provides you with the
capability of creating multiple virtual terminals and multiplex between them. More about tmux
can be
found at tmux GitHub wiki page . Tmux has several useful shortcuts
that allow you to split the terminals, open new tabs etc - it's pretty useful to learn it.
Another way is to exec into Breeze terminal from the host's terminal. Often you can
have multiple terminals in the host (Linux/MacOS/WSL2 on Windows) and you can simply use those terminals
to enter the running container. It's as easy as launching breeze exec
while you already started the
Breeze environment. You will be dropped into bash and environment variables will be read in the same
way as when you enter the environment. You can do it multiple times and open as many terminals as you need.
To shrink the Docker image, not all tools are pre-installed in the Docker image. But we have made sure that there is an easy process to install additional tools.
Additional tools are installed in /files/bin
. This path is added to $PATH
, so your shell will
automatically autocomplete files that are in that directory. You can also keep the binaries for your tools
in this directory if you need to.
Installation scripts
For the development convenience, we have also provided installation scripts for commonly used tools. They are
installed to /files/opt/
, so they are preserved after restarting the Breeze environment. Each script
is also available in $PATH
, so just type install_<TAB>
to get a list of tools.
Currently available scripts:
install_aws.sh
- installs the AWS CLI includinginstall_az.sh
- installs the Azure CLI includinginstall_gcloud.sh
- installs the Google Cloud SDK includinggcloud
,gsutil
.install_imgcat.sh
- installs imgcat - Inline Images Protocol for iTerm2 (Mac OS only)install_java.sh
- installs the OpenJDK 8u41install_kubectl.sh
- installs the Kubernetes command-line tool, kubectlinstall_terraform.sh
- installs Terraform
When Breeze starts, it can start additional integrations. Those are additional docker containers that are started in the same docker-compose command. Those are required by some of the tests as described in TESTING.rst#airflow-integration-tests.
By default Breeze starts only airflow container without any integration enabled. If you selected
postgres
or mysql
backend, the container for the selected backend is also started (but only the one
that is selected). You can start the additional integrations by passing --integration
flag
with appropriate integration name when starting Breeze. You can specify several --integration
flags
to start more than one integration at a time.
Finally you can specify --integration all
to start all integrations.
Once integration is started, it will continue to run until the environment is stopped with
breeze stop
command. or restarted via breeze restart
command
Note that running integrations uses significant resources - CPU and memory.
With Breeze you can build images that are used by Airflow CI and production ones.
For all development tasks, unit tests, integration tests, and static code checks, we use the
CI image maintained on the DockerHub in the apache/airflow-ci
repository.
This Docker image contains a lot of test-related packages (size of ~1GB).
Its tag follows the pattern of <BRANCH>-python<PYTHON_MAJOR_MINOR_VERSION>-ci
(for example, apache/airflow:main-python3.6-ci
or apache/airflow-ci:v2-1-test-python3.6-ci
).
The image is built using the Dockerfile.ci Dockerfile.
The CI image is built automatically as needed, however it can be rebuilt manually with
build-image
command. The production
image should be built manually - but also a variant of this image is built automatically when
kubernetes tests are executed see Running Kubernetes tests
Building the image first time pulls a pre-built version of images from the Docker Hub, which may take some
time. But for subsequent source code changes, no wait time is expected.
However, changes to sensitive files like setup.py
or Dockerfile.ci
will trigger a rebuild
that may take more time though it is highly optimized to only rebuild what is needed.
Breeze has built in mechanism to check if your local image has not diverged too much from the latest image build on CI. This might happen when for example latest patches have been released as new Python images or when significant changes are made in the Dockerfile. In such cases, Breeze will download the latest images before rebuilding because this is usually faster than rebuilding the image.
In most cases, rebuilding an image requires network connectivity (for example, to download new
dependencies). If you work offline and do not want to rebuild the images when needed, you can set the
FORCE_ANSWER_TO_QUESTIONS
variable to no
as described in the
Setting default behaviour for user interaction section.
Breeze can also be used to prepare airflow packages - both "apache-airflow" main package and provider packages.
You can read more about testing provider packages in TESTING.rst
There are several commands that you can run in Breeze to manage and build packages:
- preparing Provider Readme files
- preparing Airflow packages
- preparing Provider packages
Preparing provider readme files is part of the release procedure by the release managers and it is described in detail in dev .
The packages are prepared in dist
folder. Note, that this command cleans up the dist
folder
before running, so you should run it before generating airflow package below as it will be removed.
The below example builds provider packages in the wheel format.
./breeze prepare-provider-packages
If you run this command without packages, you will prepare all packages, you can however specify
providers that you would like to build. By default both
types of packages are prepared (
wheel
and sdist
, but you can change it providing optional --package-format flag.
./breeze prepare-provider-packages google amazon
You can see all providers available by running this command:
./breeze prepare-provider-packages -- --help
You can also prepare airflow packages using breeze:
./breeze prepare-airflow-packages
This prepares airflow .whl package in the dist folder.
Again, you can specify optional --package-format
flag to build selected formats of airflow packages,
default is to build both
type of packages sdist
and wheel
.
./breeze prepare-airflow-packages --package-format=wheel
The Production image is also maintained on the DockerHub in both apache/airflow
(for tagged and latest
releases) or apache/airflow-ci
repository (for branches). This Docker image (built using official
Dockerfile) contains size-optimised Airflow installation with selected extras and dependencies. Its tag follows
the pattern of <BRANCH>-python<PYTHON_MAJOR_MINOR_VERSION>
(for example, apache/airflow-ci:main-python3.6
or apache/airflow-ci:v2-1-test-python3.6
) or in case of production images tagged with releases
apache/airflow:2.1.2-python3.8
or apache/airflow:latest
or apache/airflow:latest-python3.8
.
However in many cases you want to add your own custom version of the image - with added apt dependencies,
python dependencies, additional Airflow extras. Breeze's build-image
command helps to build your own,
customized variant of the image that contains everything you need.
You can switch to building the production image by adding --production-image
flag to the build_image
command. Note, that the images can also be build using docker build
command by passing appropriate
build-args as described in IMAGES.rst , but Breeze provides several flags that
makes it easier to do it. You can see all the flags by running ./breeze build-image --help
,
but here typical examples are presented:
./breeze build-image --production-image --additional-extras "jira"
This installs additional jira
extra while installing airflow in the image.
./breeze build-image --production-image --additional-python-deps "torchio==0.17.10"
This install additional pypi dependency - torchio in specified version.
./breeze build-image --production-image --additional-dev-apt-deps "libasound2-dev" \
--additional-runtime-apt-deps "libasound2"
This install additional apt dependencies - libasound2-dev
in build image and libasound
in the
final image. Those are development dependencies that might be needed to build and use python packages added
via the --additional-python-deps
flag. The dev
dependencies are not installed in the final
production image, they are only installed in the build "segment" of the production image that is used
as an intermediate step to build the final image. Usually names of the dev
dependencies end with -dev
suffix and they need to also be paired with corresponding runtime dependency added for the runtime image
(without -dev).
./breeze build-image --production-image --python 3.7 --additional-dev-deps "libasound2-dev" \
--additional-runtime-apt-deps "libasound2"
Same as above but uses python 3.7.
You can run static checks via Breeze. You can also run them via pre-commit command but with auto-completion Breeze makes it easier to run selective static checks. If you press <TAB> after the static-check and if you have auto-complete setup you should see auto-completable list of all checks available.
./breeze static-check mypy
The above will run mypy check for currently staged files.
You can also add arbitrary pre-commit flag after --
./breeze static-check mypy -- --all-files
The above will run mypy check for all files.
If you want ever need to get a list of the files that will be checked (for troubleshooting when playing with the
--from-ref
and --to-ref
breeze static-check identity --verbose # currently staged files
breeze static-check identity --verbose -- --from-ref $(git merge-base main HEAD) --to-ref HEAD # branch updates
To build documentation in Breeze, use the build-docs
command:
./breeze build-docs
Results of the build can be found in the docs/_build
folder.
The documentation build consists of three steps:
- verifying consistency of indexes
- building documentation
- spell checking
You can choose only one stage of the two by providing --spellcheck-only
or --docs-only
after
extra --
flag.
./breeze build-docs -- --spellcheck-only
Often errors during documentation generation come from the docstrings of auto-api generated classes.
During the docs building auto-api generated files are stored in the docs/_api
folder. This helps you
easily identify the location the problems with documentation originated from.
Whenever setup.py gets modified, the CI main job will re-generate constraint files. Those constraint
files are stored in separated orphan branches: constraints-main
, constraints-2-0
.
Those are constraint files as described in detail in the CONTRIBUTING.rst#pinned-constraint-files contributing documentation.
You can use ./breeze generate-constraints
command to manually generate constraints for a single python
version and single constraint mode like this:
./breeze generate-constraints --generate-constraints-mode pypi-providers
Constraints are generated separately for each python version and there are separate constraints modes:
- 'constraints' - those are constraints generated by matching the current airflow version from sources
- and providers that are installed from PyPI. Those are constraints used by the users who want to
install airflow with pip. Use
pypi-providers
mode for that.
- "constraints-source-providers" - those are constraints generated by using providers installed from
current sources. While adding new providers their dependencies might change, so this set of providers
is the current set of the constraints for airflow and providers from the current main sources.
Those providers are used by CI system to keep "stable" set of constraints. Use
source-providers
mode for that. - "constraints-no-providers" - those are constraints generated from only Apache Airflow, without any
providers. If you want to manage airflow separately and then add providers individually, you can
use those. Use
no-providers
mode for that.
In case someone modifies setup.py, the CRON
scheduled CI build automatically upgrades and
pushes changed to the constraint files, however you can also perform test run of this locally using
the procedure described in CONTRIBUTING.rst#mnully-generating-constraint-files which utilises
multiple processors on your local machine to generate such constraints faster.
This bumps the constraint files to latest versions and stores hash of setup.py. The generated constraint
and setup.py hash files are stored in the files
folder and while generating the constraints diff
of changes vs the previous constraint files is printed.
You can set up your host IDE (for example, IntelliJ's PyCharm/Idea) to work with Breeze and benefit from all the features provided by your IDE, such as local and remote debugging, language auto-completion, documentation support, etc.
To use your host IDE with Breeze:
Create a local virtual environment:
You can use any of the following wrappers to create and manage your virtual environments: pyenv, pyenv-virtualenv, or virtualenvwrapper.
Ideally, you should have virtualenvs for all Python versions supported by Airflow (3.5, 3.6, 3.7)
Use the right command to activate the virtualenv (
workon
if you use virtualenvwrapper orpyenv activate
if you use pyenv.Initialize the created local virtualenv:
./breeze initialize-local-virtualenv --python 3.8
- Select the virtualenv you created as the project's default virtualenv in your IDE.
Note that you can also use the local virtualenv for Airflow development without Breeze. This is a lightweight solution that has its own limitations.
More details on using the local virtualenv are available in the LOCAL_VIRTUALENV.rst.
Breeze helps with running Kubernetes tests in the same environment/way as CI tests are run. Breeze helps to setup KinD cluster for testing, setting up virtualenv and downloads the right tools automatically to run the tests.
This is described in detail in Testing Kubernetes.
After starting up, the environment runs in the background and takes precious memory. You can always stop it via:
./breeze stop
When you are in the CI container, the following directories are used:
/opt/airflow - Contains sources of Airflow mounted from the host (AIRFLOW_SOURCES).
/root/airflow - Contains all the "dynamic" Airflow files (AIRFLOW_HOME), such as:
airflow.db - sqlite database in case sqlite is used;
dags - folder with non-test dags (test dags are in /opt/airflow/tests/dags);
logs - logs from Airflow executions;
unittest.cfg - unit test configuration generated when entering the environment;
webserver_config.py - webserver configuration generated when running Airflow in the container.
Note that when running in your local environment, the /root/airflow/logs
folder is actually mounted
from your logs
directory in the Airflow sources, so all logs created in the container are automatically
visible in the host as well. Every time you enter the container, the logs
directory is
cleaned so that logs do not accumulate.
When you are in the production container, the following directories are used:
/opt/airflow - Contains sources of Airflow mounted from the host (AIRFLOW_SOURCES).
/root/airflow - Contains all the "dynamic" Airflow files (AIRFLOW_HOME), such as:
airflow.db - sqlite database in case sqlite is used;
dags - folder with non-test dags (test dags are in /opt/airflow/tests/dags);
logs - logs from Airflow executions;
unittest.cfg - unit test configuration generated when entering the environment;
webserver_config.py - webserver configuration generated when running Airflow in the container.
Note that when running in your local environment, the /root/airflow/logs
folder is actually mounted
from your logs
directory in the Airflow sources, so all logs created in the container are automatically
visible in the host as well. Every time you enter the container, the logs
directory is
cleaned so that logs do not accumulate.
To run other commands/executables inside the Breeze Docker-based environment, use the
./breeze shell
command. You should add your command as -c "command" after --
as extra arguments.
./breeze shell -- -c "ls -la"
To run Docker Compose commands (such as help
, pull
, etc), use the
docker-compose
command. To add extra arguments, specify them
after --
as extra arguments.
./breeze docker-compose pull -- --ignore-pull-failures
You can also restart the environment and enter it via:
./breeze restart
Sometimes during the build, you are asked whether to perform an action, skip it, or quit. This happens when rebuilding or removing an image - actions that take a lot of time and could be potentially destructive.
For automation scripts, you can export one of the three variables to control the default interaction behaviour:
export FORCE_ANSWER_TO_QUESTIONS="yes"
If FORCE_ANSWER_TO_QUESTIONS
is set to yes
, the images are automatically rebuilt when needed.
Images are deleted without asking.
export FORCE_ANSWER_TO_QUESTIONS="no"
If FORCE_ANSWER_TO_QUESTIONS
is set to no
, the old images are used even if rebuilding is needed.
This is useful when you work offline. Deleting images is aborted.
export FORCE_ANSWER_TO_QUESTIONS="quit"
If FORCE_ANSWER_TO_QUESTIONS
is set to quit
, the whole script is aborted. Deleting images is aborted.
If more than one variable is set, yes
takes precedence over no
, which takes precedence over quit
.
On Linux, there is a problem with propagating ownership of created files (a known Docker problem). The files and directories created in the container are not owned by the host user (but by the root user in our case). This may prevent you from switching branches, for example, if files owned by the root user are created within your sources. In case you are on a Linux host and have some files in your sources created by the root user, you can fix the ownership of those files by running this script:
./scripts/ci/tools/ci_fix_ownership.sh
Important sources of Airflow are mounted inside the airflow
container that you enter.
This means that you can continue editing your changes on the host in your favourite IDE and have them
visible in the Docker immediately and ready to test without rebuilding images. You can disable mounting
by specifying --skip-mounting-local-sources
flag when running Breeze. In this case you will have sources
embedded in the container and changes to these sources will not be persistent.
After you run Breeze for the first time, you will have empty directory files
in your source code,
which will be mapped to /files
in your Docker container. You can pass there any files you need to
configure and run Docker. They will not be removed between Docker runs.
By default /files/dags
folder is mounted from your local <AIRFLOW_SOURCES>/files/dags
and this is
the directory used by airflow scheduler and webserver to scan dags for. You can use it to test your dags
from local sources in Airflow. If you wish to add local DAGs that can be run by Breeze.
When you run Airflow Breeze, the following ports are automatically forwarded:
- 28080 -> forwarded to Airflow webserver -> airflow:8080
- 25555 -> forwarded to Flower dashboard -> airflow:5555
- 25433 -> forwarded to Postgres database -> postgres:5432
- 23306 -> forwarded to MySQL database -> mysql:3306
- 26379 -> forwarded to Redis broker -> redis:6379
You can connect to these ports/databases using:
- Webserver:
http://127.0.0.1:28080
- Flower:
http://127.0.0.1:25555
- Postgres:
jdbc:postgresql://127.0.0.1:25433/airflow?user=postgres&password=airflow
- Mysql:
jdbc:mysql://127.0.0.1:23306/airflow?user=root
- Redis:
redis://127.0.0.1:26379/0`
Start the webserver manually with the airflow webserver
command if you want to connect
to the webserver. You can use tmux
to multiply terminals. You may need to create a user prior to
running the webserver in order to log in. This can be done with the following command:
airflow users create --role Admin --username admin --password admin --email [email protected] --firstname foo --lastname bar
For databases, you need to run airflow db reset
at least once (or run some tests) after you started
Airflow Breeze to get the database/tables created. You can connect to databases with IDE or any other
database client:
You can change the used host port numbers by setting appropriate environment variables:
WEBSERVER_HOST_PORT
POSTGRES_HOST_PORT
MYSQL_HOST_PORT
If you set these variables, next time when you enter the environment the new ports should be in effect.
If you need to change apt dependencies in the Dockerfile.ci
, add Python packages in setup.py
or
add JavaScript dependencies in package.json
, you can either add dependencies temporarily for a single
Breeze session or permanently in setup.py
, Dockerfile.ci
, or package.json
files.
You can install dependencies inside the container using sudo apt install
, pip install
or
yarn install
(in airflow/www
folder) respectively. This is useful if you want to test something
quickly while you are in the container. However, these changes are not retained: they disappear once you
exit the container (except for the node.js dependencies if your sources are mounted to the container).
Therefore, if you want to retain a new dependency, follow the second option described below.
You can add dependencies to the Dockerfile.ci
, setup.py
or package.json
and rebuild the image.
This should happen automatically if you modify any of these files.
After you exit the container and re-run breeze
, Breeze detects changes in dependencies,
asks you to confirm rebuilding the image and proceeds with rebuilding if you confirm (or skip it
if you do not confirm). After rebuilding is done, Breeze drops you to shell. You may also use the
build-image
command to only rebuild CI image and not to go into shell.
During development, changing dependencies in apt-get
closer to the top of the Dockerfile.ci
invalidates cache for most of the image. It takes long time for Breeze to rebuild the image.
So, it is a recommended practice to add new dependencies initially closer to the end
of the Dockerfile.ci
. This way dependencies will be added incrementally.
Before merge, these dependencies should be moved to the appropriate apt-get install
command,
which is already in the Dockerfile.ci
.
This is the current syntax for ./breeze:

Detailed usage
####################################################################################################
Detailed usage for command: shell
breeze shell [FLAGS] [-- <EXTRA_ARGS>]
This is default subcommand if no subcommand is used.
Enters interactive shell where you can run all tests, start Airflow webserver, scheduler,
workers, interact with the database, run DAGs etc. It is the default command if no command
is selected. The shell is executed in the container and in case integrations are chosen,
the integrations will be started as separated docker containers - under the docker-compose
supervision. Local sources are by default mounted to within the container so you can edit
them locally and run tests immediately in the container. Several folders ('files', 'dist')
are also mounted so that you can exchange files between the host and container.
The 'files/airflow-breeze-config/variables.env' file can contain additional variables
and setup. This file is automatically sourced when you enter the container. Database
and webserver ports are forwarded to appropriate database/webserver so that you can
connect to it from your host environment.
You can also pass <EXTRA_ARGS> after -- they will be passed as bash parameters, this is
especially useful to pass bash options, for example -c to execute command:
'breeze shell -- -c "ls -la"'
'breeze -- -c "ls -la"'
For DockerHub pull: --dockerhub-user and --dockerhub-repo flags can be used to specify
the repository to pull from. For GitHub repository, the --github-repository
flag can be used for the same purpose. You can also use --github-image-id <COMMIT_SHA> in case
you want to pull the image with specific COMMIT_SHA tag.
'breeze shell \
--github-image-id 9a621eaa394c0a0a336f8e1b31b35eff4e4ee86e' - pull/use image with SHA
'breeze \
--github-image-id 9a621eaa394c0a0a336f8e1b31b35eff4e4ee86e' - pull/use image with SHA
Most flags are applicable to the shell command as it will run build when needed.
####################################################################################################
Detailed usage for command: build-docs
breeze build-docs [-- <EXTRA_ARGS>]
Builds Airflow documentation. The documentation is build inside docker container - to
maintain the same build environment for everyone. Appropriate sources are mapped from
the host to the container so that latest sources are used. The folders where documentation
is generated ('docs/_build') are also mounted to the container - this way results of
the documentation build is available in the host.
The possible extra args are: --docs-only, --spellcheck-only, --package-filter, --help
####################################################################################################
Detailed usage for command: build-image
breeze build-image [FLAGS]
Builds docker image (CI or production) without entering the container. You can pass
additional options to this command, such as:
Choosing python version:
'--python'
Choosing cache option:
'--build-cache-local' or '-build-cache-pulled', or '--build-cache-none'
Choosing whether to force pull images or force build the image:
'--force-build-image',
'--force-pull-image', '--force-pull-base-python-image'
You can also pass '--production-image' flag to build production image rather than CI image.
For DockerHub pulling of base images: '--dockerhub-user' and '--dockerhub-repo' flags can be
used to specify the repository to pull from. For GitHub repository, the '--github-repository'
flag can be used for the same purpose.
Flags:
-p, --python PYTHON_MAJOR_MINOR_VERSION
Python version used for the image. This is always major/minor version.
One of:
3.6 3.7 3.8
-a, --install-airflow-version INSTALL_AIRFLOW_VERSION
Uses different version of Airflow when building PROD image.
2.0.2 2.0.1 2.0.0 wheel sdist
-t, --install-airflow-reference INSTALL_AIRFLOW_REFERENCE
Installs Airflow directly from reference in GitHub when building PROD image.
This can be a GitHub branch like main or v2-1-test, or a tag like 2.1.0a1.
--installation-method INSTALLATION_METHOD
Method of installing Airflow in PROD image - either from the sources ('.')
or from package 'apache-airflow' to install from PyPI.
Default in Breeze is to install from sources. One of:
. apache-airflow
--upgrade-to-newer-dependencies
Upgrades PIP packages to latest versions available without looking at the constraints.
--continue-on-pip-check-failure
Continue even if 'pip check' fails.
-I, --production-image
Use production image for entering the environment and builds (not for tests).
-F, --force-build-images
Forces building of the local docker images. The images are rebuilt
automatically for the first time or when changes are detected in
package-related files, but you can force it using this flag.
-P, --force-pull-images
Forces pulling of images from DockerHub before building to populate cache. The
images are pulled by default only for the first time you run the
environment, later the locally build images are used as cache.
--force-pull-base-python-image
Forces pulling of Python base image from DockerHub before building to
populate cache. This should only be run in case we need to update to latest available
Python base image. This should be a rare and manually triggered event. Also this flag
is used in the scheduled run in CI when we rebuild all the images from the scratch
and run the tests to see if the latest python images do not fail our tests.
--cleanup-docker-context-files
Removes whl and tar.gz files created in docker-context-files before running the command.
In case there are some files there it unnecessarily increases the context size and
makes the COPY . always invalidated - if you happen to have those files when you build your
image.
Customization options:
-E, --extras EXTRAS
Extras to pass to build images The default are different for CI and production images:
CI image:
devel_ci
Production image:
async,amazon,celery,cncf.kubernetes,docker,dask,elasticsearch,ftp,grpc,hashicorp,
http,ldap,google,microsoft.azure,mysql,postgres,redis,sendgrid,sftp,slack,ssh,statsd,
virtualenv
--image-tag TAG
Additional tag in the image.
--skip-installing-airflow-providers-from-sources
By default 'pip install' in Airflow 2.0 installs only the provider packages that
are needed by the extras. When you build image during the development (which is
default in Breeze) all providers are installed by default from sources.
You can disable it by adding this flag but then you have to install providers from
wheel packages via --use-packages-from-dist flag.
--disable-pypi-when-building
Disable installing Airflow from pypi when building. If you use this flag and want
to install Airflow, you have to install it from packages placed in
'docker-context-files' and use --install-from-docker-context-files flag.
--additional-extras ADDITIONAL_EXTRAS
Additional extras to pass to build images The default is no additional extras.
--additional-python-deps ADDITIONAL_PYTHON_DEPS
Additional python dependencies to use when building the images.
--dev-apt-command DEV_APT_COMMAND
The basic command executed before dev apt deps are installed.
--additional-dev-apt-command ADDITIONAL_DEV_APT_COMMAND
Additional command executed before dev apt deps are installed.
--additional-dev-apt-deps ADDITIONAL_DEV_APT_DEPS
Additional apt dev dependencies to use when building the images.
--dev-apt-deps DEV_APT_DEPS
The basic apt dev dependencies to use when building the images.
--additional-dev-apt-deps ADDITIONAL_DEV_DEPS
Additional apt dev dependencies to use when building the images.
--additional-dev-apt-envs ADDITIONAL_DEV_APT_ENVS
Additional environment variables set when adding dev dependencies.
--runtime-apt-command RUNTIME_APT_COMMAND
The basic command executed before runtime apt deps are installed.
--additional-runtime-apt-command ADDITIONAL_RUNTIME_APT_COMMAND
Additional command executed before runtime apt deps are installed.
--runtime-apt-deps ADDITIONAL_RUNTIME_APT_DEPS
The basic apt runtime dependencies to use when building the images.
--additional-runtime-apt-deps ADDITIONAL_RUNTIME_DEPS
Additional apt runtime dependencies to use when building the images.
--additional-runtime-apt-envs ADDITIONAL_RUNTIME_APT_DEPS
Additional environment variables set when adding runtime dependencies.
Build options:
--disable-mysql-client-installation
Disables installation of the mysql client which might be problematic if you are building
image in controlled environment. Only valid for production image.
--constraints-location
Url to the constraints file. In case of the production image it can also be a path to the
constraint file placed in 'docker-context-files' folder, in which case it has to be
in the form of '/docker-context-files/<NAME_OF_THE_FILE>'
--disable-pip-cache
Disables GitHub PIP cache during the build. Useful if GitHub is not reachable during build.
--install-from-docker-context-files
This flag is used during image building. If it is used additionally to installing
Airflow from PyPI, the packages are installed from the .whl and .tar.gz packages placed
in the 'docker-context-files' folder. The same flag can be used during entering the image in
the CI image - in this case also the .whl and .tar.gz files will be installed automatically
-C, --force-clean-images
Force build images with cache disabled. This will remove the pulled or build images
and start building images from scratch. This might take a long time.
-r, --skip-rebuild-check
Skips checking image for rebuilds. It will use whatever image is available locally/pulled.
-L, --build-cache-local
Uses local cache to build images. No pulled images will be used, but results of local
builds in the Docker cache are used instead. This will take longer than when the pulled
cache is used for the first time, but subsequent '--build-cache-local' builds will be
faster as they will use mostly the locally build cache.
This is default strategy used by the Production image builds.
-U, --build-cache-pulled
Uses images pulled from registry (either DockerHub or GitHub depending on
--use-github-registry flag) to build images. The pulled images will be used as cache.
Those builds are usually faster than when ''--build-cache-local'' with the exception if
the registry images are not yet updated. The DockerHub images are updated nightly and the
GitHub images are updated after merges to main so it might be that the images are still
outdated vs. the latest version of the Dockerfiles you are using. In this case, the
''--build-cache-local'' might be faster, especially if you iterate and change the
Dockerfiles yourself.
This is default strategy used by the CI image builds.
-X, --build-cache-disabled
Disables cache during docker builds. This is useful if you want to make sure you want to
rebuild everything from scratch.
This strategy is used by default for both Production and CI images for the scheduled
(nightly) builds in CI.
-D, --dockerhub-user DOCKERHUB_USER
DockerHub user used to pull, push and build images. Default: apache.
-H, --dockerhub-repo DOCKERHUB_REPO
DockerHub repository used to pull, push, build images. Default: airflow-ci.
-c, --use-github-registry
If GitHub registry is enabled, pulls and pushes are done from the GitHub registry not
DockerHub. You need to be logged in to the registry in order to be able to pull/push from
and you need to be committer to push to Apache Airflow' GitHub registry.
--github-registry GITHUB_REGISTRY
GitHub registry used. GitHub has legacy Packages registry and Public Beta Container
registry.
Default: docker.pkg.github.com.
If you use this flag, automatically --use-github-registry flag is enabled.
docker.pkg.github.com ghcr.io
-g, --github-repository GITHUB_REPOSITORY
GitHub repository used to pull, push images when cache is used.
Default: apache/airflow.
If you use this flag, automatically --use-github-registry flag is enabled.
-v, --verbose
Show verbose information about executed docker, kind, kubectl, helm commands. Useful for
debugging - when you run breeze with --verbose flags you will be able to see the commands
executed under the hood and copy&paste them to your terminal to debug them more easily.
Note that you can further increase verbosity and see all the commands executed by breeze
by running 'export VERBOSE_COMMANDS="true"' before running breeze.
--dry-run-docker
Only show docker commands to execute instead of actually executing them. The docker
commands are printed in yellow color.
####################################################################################################
Detailed usage for command: cleanup-image
breeze cleanup-image [FLAGS]
Removes the breeze-related images created in your local docker image cache. This will
not reclaim space in docker cache. You need to 'docker system prune' (optionally
with --all) to reclaim that space.
Flags:
-p, --python PYTHON_MAJOR_MINOR_VERSION
Python version used for the image. This is always major/minor version.
One of:
3.6 3.7 3.8
-I, --production-image
Use production image for entering the environment and builds (not for tests).
-v, --verbose
Show verbose information about executed docker, kind, kubectl, helm commands. Useful for
debugging - when you run breeze with --verbose flags you will be able to see the commands
executed under the hood and copy&paste them to your terminal to debug them more easily.
Note that you can further increase verbosity and see all the commands executed by breeze
by running 'export VERBOSE_COMMANDS="true"' before running breeze.
--dry-run-docker
Only show docker commands to execute instead of actually executing them. The docker
commands are printed in yellow color.
####################################################################################################
Detailed usage for command: exec
breeze exec [-- <EXTRA_ARGS>]
Execs into interactive shell to an already running container. The container mus be started
already by breeze shell command. If you are not familiar with tmux, this is the best
way to run multiple processes in the same container at the same time for example scheduler,
webserver, workers, database console and interactive terminal.
####################################################################################################
Detailed usage for command: generate-constraints
breeze generate-constraints [FLAGS]
Generates pinned constraint files with all extras from setup.py. Those files are generated in
files folder - separate files for different python version. Those constraint files when
pushed to orphan constraints-main, constraints-2-0 branches are used
to generate repeatable CI builds as well as run repeatable production image builds and
upgrades when you want to include installing or updating some of the released providers
released at the time particular airflow version was released. You can use those
constraints to predictably install released Airflow versions. This is mainly used to test
the constraint generation or manually fix them - constraints are pushed to the orphan
branches by a successful scheduled CRON job in CI automatically, but sometimes manual fix
might be needed.
Flags:
--generate-constraints-mode GENERATE_CONSTRAINTS_MODE
Mode of generating constraints - determines whether providers are installed when generating
constraints and which version of them (either the ones from sources are used or the ones
from pypi.
One of:
source-providers pypi-providers no-providers
-p, --python PYTHON_MAJOR_MINOR_VERSION
Python version used for the image. This is always major/minor version.
One of:
3.6 3.7 3.8
-v, --verbose
Show verbose information about executed docker, kind, kubectl, helm commands. Useful for
debugging - when you run breeze with --verbose flags you will be able to see the commands
executed under the hood and copy&paste them to your terminal to debug them more easily.

by running 'export VERBOSE_COMMANDS="true"' before running breeze.
--dry-run-docker
Only show docker commands to execute instead of actually executing them. The docker
commands are printed in yellow color.
####################################################################################################
Detailed usage for command: push-image
breeze push_image [FLAGS]
Pushes images to docker registry. You can push the images to DockerHub registry (default)
or to the GitHub registry (if --use-github-registry flag is used).
For DockerHub pushes: --dockerhub-user and --dockerhub-repo flags can be used to specify
the repository to push to. For GitHub repository, the --github-repository
flag can be used for the same purpose. You can also add
--github-image-id <COMMIT_SHA> in case you want to push image with specific
SHA tag. In case you specify --github-repository or --github-image-id, you
do not need to specify --use-github-registry flag.
You can also add --production-image flag to switch to production image (default is CI one)
Examples:
'breeze push-image' or
'breeze push-image --dockerhub-user user' to push to your private registry or
'breeze push-image --production-image' - to push production image or
'breeze push-image --use-github-registry' - to push to GitHub image registry or
'breeze push-image \
--github-repository user/airflow' - to push to your user's fork
'breeze push-image \
--github-image-id 9a621eaa394c0a0a336f8e1b31b35eff4e4ee86e' - to push with COMMIT_SHA
Flags:
-D, --dockerhub-user DOCKERHUB_USER
DockerHub user used to pull, push and build images. Default: apache.
-H, --dockerhub-repo DOCKERHUB_REPO
DockerHub repository used to pull, push, build images. Default: airflow-ci.
-c, --use-github-registry
If GitHub registry is enabled, pulls and pushes are done from the GitHub registry not
DockerHub. You need to be logged in to the registry in order to be able to pull/push from
and you need to be committer to push to Apache Airflow' GitHub registry.
--github-registry GITHUB_REGISTRY
GitHub registry used. GitHub has legacy Packages registry and Public Beta Container
registry.
Default: docker.pkg.github.com.
If you use this flag, automatically --use-github-registry flag is enabled.
docker.pkg.github.com ghcr.io
-g, --github-repository GITHUB_REPOSITORY
GitHub repository used to pull, push images when cache is used.
Default: apache/airflow.
If you use this flag, automatically --use-github-registry flag is enabled.
-s, --github-image-id COMMIT_SHA
<COMMIT_SHA> of the image. Images in GitHub registry are stored with those
to be able to easily find the image for particular CI runs. Once you know the
<COMMIT_SHA>, you can specify it in github-image-id flag and Breeze will
automatically pull and use that image so that you can easily reproduce a problem
that occurred in CI.
If you use this flag, automatically --use-github-registry is enabled.
Default: latest.
-v, --verbose
Show verbose information about executed docker, kind, kubectl, helm commands. Useful for
debugging - when you run breeze with --verbose flags you will be able to see the commands
executed under the hood and copy&paste them to your terminal to debug them more easily.
Note that you can further increase verbosity and see all the commands executed by breeze
by running 'export VERBOSE_COMMANDS="true"' before running breeze.
--dry-run-docker

commands are printed in yellow color.
####################################################################################################
Detailed usage for command: initialize-local-virtualenv
breeze initialize-local-virtualenv [FLAGS]
Initializes locally created virtualenv installing all dependencies of Airflow
taking into account the constraints for the version specified.
This local virtualenv can be used to aid auto-completion and IDE support as
well as run unit tests directly from the IDE. You need to have virtualenv
activated before running this command.
Flags:
-p, --python PYTHON_MAJOR_MINOR_VERSION
Python version used for the image. This is always major/minor version.
One of:
3.6 3.7 3.8
####################################################################################################
Detailed usage for command: prepare-airflow-packages
breeze prepare-airflow-packages [FLAGS]
Prepares airflow packages (sdist and wheel) in dist folder. Note that
prepare-provider-packages command cleans up the dist folder, so if you want also
to generate provider packages, make sure you run prepare-provider-packages first,
and prepare-airflow-packages second. You can specify optional
--version-suffix-for-pypi flag to generate rc candidates for PyPI packages.
The packages are prepared in dist folder
Examples:
'breeze prepare-airflow-packages --package-format wheel' or
'breeze prepare-airflow-packages --version-suffix-for-pypi rc1'
Flags:
--package-format PACKAGE_FORMAT
Chooses format of packages to prepare.
One of:
both,sdist,wheel
Default: both
-S, --version-suffix-for-pypi SUFFIX
Adds optional suffix to the version in the generated provider package. It can be used
to generate rc1/rc2 ... versions of the packages to be uploaded to PyPI.
-N, --version-suffix-for-svn SUFFIX
Adds optional suffix to the generated names of package. It can be used to generate
rc1/rc2 ... versions of the packages to be uploaded to SVN.
-v, --verbose
Show verbose information about executed docker, kind, kubectl, helm commands. Useful for
debugging - when you run breeze with --verbose flags you will be able to see the commands
executed under the hood and copy&paste them to your terminal to debug them more easily.
Note that you can further increase verbosity and see all the commands executed by breeze
by running 'export VERBOSE_COMMANDS="true"' before running breeze.
--dry-run-docker
Only show docker commands to execute instead of actually executing them. The docker
commands are printed in yellow color.
####################################################################################################
Detailed usage for command: setup-autocomplete
breeze setup-autocomplete
Sets up autocomplete for breeze commands. Once you do it you need to re-enter the bash
shell and when typing breeze command <TAB> will provide autocomplete for
parameters and values.
####################################################################################################
Detailed usage for command: start-airflow
breeze start-airflow
Like the Shell command this will enter the interactive shell, but it will also start
automatically the Scheduler and the Webserver. It will leave you in a tmux session where you
can also observe what is happening in your Airflow.
This is a convenient way to setup a development environment. Your dags will be loaded from the
folder 'files/dags' on your host machine (it could take some times).
If you want to load default connections and example dags you can use the dedicated flags.
Flags:
--use-airflow-version AIRFLOW_SPECIFICATION
In CI image, installs Airflow at runtime from PIP released version or using
the installation method specified (sdist, wheel, none). When 'none' is used,
airflow is just removed. In this case airflow package should be added to dist folder
and --use-packages-from-dist flag should be used.
2.0.2 2.0.1 2.0.0 wheel sdist none
--use-packages-from-dist
In CI image, if specified it will look for packages placed in dist folder and
it will install the packages after entering the image.
This is useful for testing provider packages.
--load-example-dags
Include Airflow example dags.
--load-default-connections
Include Airflow Default Connections.
####################################################################################################
Detailed usage for command: stop
breeze stop
Brings down running docker compose environment. When you start the environment, the docker
containers will continue running so that startup time is shorter. But they take quite a lot of
memory and CPU. This command stops all running containers from the environment.
Flags:
--preserve-volumes
Use this flag if you would like to preserve data volumes from the databases used
by the integrations. By default, those volumes are deleted, so when you run 'stop'
or 'restart' commands you start from scratch, but by using this flag you can
preserve them. If you want to delete those volumes after stopping Breeze, just
run the 'breeze stop' again without this flag.
####################################################################################################
Detailed usage for command: restart
breeze restart [FLAGS]
Restarts running docker compose environment. When you restart the environment, the docker
containers will be restarted. That includes cleaning up the databases. This is
especially useful if you switch between different versions of Airflow.
Flags:
--preserve-volumes
Use this flag if you would like to preserve data volumes from the databases used
by the integrations. By default, those volumes are deleted, so when you run 'stop'
or 'restart' commands you start from scratch, but by using this flag you can
preserve them. If you want to delete those volumes after stopping Breeze, just
run the 'breeze stop' again without this flag.
####################################################################################################

Toggles on/off asciiart displayed before starting bash shell.
####################################################################################################
Detailed usage for command: docker-compose
breeze docker-compose [FLAGS] COMMAND [-- <EXTRA_ARGS>]
Run docker-compose command instead of entering the environment. Use 'help' as command
to see available commands. The <EXTRA_ARGS> passed after -- are treated
as additional options passed to docker-compose. For example
'breeze docker-compose pull -- --ignore-pull-failures'
Flags:
-p, --python PYTHON_MAJOR_MINOR_VERSION
Python version used for the image. This is always major/minor version.
One of:
3.6 3.7 3.8
-b, --backend BACKEND
Backend to use for tests - it determines which database is used.

Detailed usage for command: kind-cluster
breeze kind-cluster [FLAGS] OPERATION
Manages host-side Kind Kubernetes cluster that is used to run Kubernetes integration tests.
It allows to start/stop/restart/status the Kind Kubernetes cluster and deploy Airflow to it.
This enables you to run tests inside the breeze environment with latest airflow images.
Note that in case of deploying airflow, the first step is to rebuild the image and loading it
to the cluster so you can also pass appropriate build image flags that will influence
rebuilding the production image. Operation is one of:
start stop restart status deploy test shell k9s
The last two operations - shell and k9s allow you to perform interactive testing with
kubernetes tests. You can enter the shell from which you can run kubernetes tests and in
another terminal you can start the k9s CLI to debug kubernetes instance. It is an easy
way to debug the kubernetes deployments.
You can read more about k9s at https://k9scli.io/
Flags:
-p, --python PYTHON_MAJOR_MINOR_VERSION
Python version used for the image. This is always major/minor version.
One of:
3.6 3.7 3.8
-F, --force-build-images
Forces building of the local docker images. The images are rebuilt
automatically for the first time or when changes are detected in
package-related files, but you can force it using this flag.
-P, --force-pull-images
Forces pulling of images from DockerHub before building to populate cache. The
images are pulled by default only for the first time you run the
environment, later the locally build images are used as cache.
--force-pull-base-python-image
Forces pulling of Python base image from DockerHub before building to
populate cache. This should only be run in case we need to update to latest available
Python base image. This should be a rare and manually triggered event. Also this flag
is used in the scheduled run in CI when we rebuild all the images from the scratch
and run the tests to see if the latest python images do not fail our tests.
--cleanup-docker-context-files
Removes whl and tar.gz files created in docker-context-files before running the command.
In case there are some files there it unnecessarily increases the context size and
makes the COPY . always invalidated - if you happen to have those files when you build your
image.
Customization options:
-E, --extras EXTRAS
Extras to pass to build images The default are different for CI and production images:
CI image:
devel_ci
Production image:
async,amazon,celery,cncf.kubernetes,docker,dask,elasticsearch,ftp,grpc,hashicorp,
http,ldap,google,microsoft.azure,mysql,postgres,redis,sendgrid,sftp,slack,ssh,statsd,
virtualenv
--image-tag TAG
Additional tag in the image.
--skip-installing-airflow-providers-from-sources
By default 'pip install' in Airflow 2.0 installs only the provider packages that
are needed by the extras. When you build image during the development (which is
default in Breeze) all providers are installed by default from sources.
You can disable it by adding this flag but then you have to install providers from
wheel packages via --use-packages-from-dist flag.
--disable-pypi-when-building
Disable installing Airflow from pypi when building. If you use this flag and want
to install Airflow, you have to install it from packages placed in
'docker-context-files' and use --install-from-docker-context-files flag.
--additional-extras ADDITIONAL_EXTRAS
Additional extras to pass to build images The default is no additional extras.
--additional-python-deps ADDITIONAL_PYTHON_DEPS
Additional python dependencies to use when building the images.
--dev-apt-command DEV_APT_COMMAND
The basic command executed before dev apt deps are installed.
--additional-dev-apt-command ADDITIONAL_DEV_APT_COMMAND
Additional command executed before dev apt deps are installed.
--additional-dev-apt-deps ADDITIONAL_DEV_APT_DEPS
Additional apt dev dependencies to use when building the images.
--dev-apt-deps DEV_APT_DEPS
The basic apt dev dependencies to use when building the images.
--additional-dev-apt-deps ADDITIONAL_DEV_DEPS
Additional apt dev dependencies to use when building the images.
--additional-dev-apt-envs ADDITIONAL_DEV_APT_ENVS
Additional environment variables set when adding dev dependencies.
--runtime-apt-command RUNTIME_APT_COMMAND
The basic command executed before runtime apt deps are installed.
--additional-runtime-apt-command ADDITIONAL_RUNTIME_APT_COMMAND
Additional command executed before runtime apt deps are installed.
--runtime-apt-deps ADDITIONAL_RUNTIME_APT_DEPS
The basic apt runtime dependencies to use when building the images.
--additional-runtime-apt-deps ADDITIONAL_RUNTIME_DEPS
Additional apt runtime dependencies to use when building the images.
--additional-runtime-apt-envs ADDITIONAL_RUNTIME_APT_DEPS
Additional environment variables set when adding runtime dependencies.
Build options:
--disable-mysql-client-installation
Disables installation of the mysql client which might be problematic if you are building
image in controlled environment. Only valid for production image.
--constraints-location
Url to the constraints file. In case of the production image it can also be a path to the
constraint file placed in 'docker-context-files' folder, in which case it has to be
in the form of '/docker-context-files/<NAME_OF_THE_FILE>'
--disable-pip-cache
Disables GitHub PIP cache during the build. Useful if GitHub is not reachable during build.
--install-from-docker-context-files
This flag is used during image building. If it is used additionally to installing
Airflow from PyPI, the packages are installed from the .whl and .tar.gz packages placed
in the 'docker-context-files' folder. The same flag can be used during entering the image in
the CI image - in this case also the .whl and .tar.gz files will be installed automatically
-C, --force-clean-images
Force build images with cache disabled. This will remove the pulled or build images
and start building images from scratch. This might take a long time.
-r, --skip-rebuild-check
Skips checking image for rebuilds. It will use whatever image is available locally/pulled.
-L, --build-cache-local
Uses local cache to build images. No pulled images will be used, but results of local
builds in the Docker cache are used instead. This will take longer than when the pulled
cache is used for the first time, but subsequent '--build-cache-local' builds will be
faster as they will use mostly the locally build cache.
This is default strategy used by the Production image builds.
-U, --build-cache-pulled
Uses images pulled from registry (either DockerHub or GitHub depending on
--use-github-registry flag) to build images. The pulled images will be used as cache.
Those builds are usually faster than when ''--build-cache-local'' with the exception if
the registry images are not yet updated. The DockerHub images are updated nightly and the
GitHub images are updated after merges to main so it might be that the images are still
outdated vs. the latest version of the Dockerfiles you are using. In this case, the
''--build-cache-local'' might be faster, especially if you iterate and change the
Dockerfiles yourself.
This is default strategy used by the CI image builds.
-X, --build-cache-disabled
Disables cache during docker builds. This is useful if you want to make sure you want to
rebuild everything from scratch.
This strategy is used by default for both Production and CI images for the scheduled
(nightly) builds in CI.

Detailed usage for command: prepare-provider-documentation
breeze prepare-provider-documentation [FLAGS] [PACKAGE_ID ...]
Prepares documentation files for provider packages.
The command is optionally followed by the list of packages to generate readme for.
If the first parameter is not formatted as a date, then today is regenerated.
If no packages are specified, readme for all packages are generated.
If no date is specified, current date + 3 days is used (allowing for PMC votes to pass).
Examples:
'breeze prepare-provider-documentation' or
'breeze prepare-provider-documentation --version-suffix-for-pypi rc1'
General form:
'breeze prepare-provider-documentation <PACKAGE_ID> ...'
* <PACKAGE_ID> is usually directory in the airflow/providers folder (for example
'google' but in several cases, it might be one level deeper separated with
'.' for example 'apache.hive'
Flags:
-S, --version-suffix-for-pypi SUFFIX
Adds optional suffix to the version in the generated provider package. It can be used
to generate rc1/rc2 ... versions of the packages to be uploaded to PyPI.
-N, --version-suffix-for-svn SUFFIX
Adds optional suffix to the generated names of package. It can be used to generate
rc1/rc2 ... versions of the packages to be uploaded to SVN.
--package-format PACKAGE_FORMAT
Chooses format of packages to prepare.
One of:
both,sdist,wheel
Default: both
--non-interactive
Runs the command in non-interactive mode.
-v, --verbose
Show verbose information about executed docker, kind, kubectl, helm commands. Useful for
debugging - when you run breeze with --verbose flags you will be able to see the commands
executed under the hood and copy&paste them to your terminal to debug them more easily.
Note that you can further increase verbosity and see all the commands executed by breeze
by running 'export VERBOSE_COMMANDS="true"' before running breeze.
--dry-run-docker
Only show docker commands to execute instead of actually executing them. The docker
commands are printed in yellow color.
####################################################################################################
Detailed usage for command: prepare-provider-packages
breeze prepare-provider-packages [FLAGS] [PACKAGE_ID ...]
Prepares provider packages. You can provide (after --) optional list of packages to prepare.
If no packages are specified, readme for all packages are generated. You can specify optional
--version-suffix-for-svn flag to generate rc candidate packages to upload to SVN or
--version-suffix-for-pypi flag to generate rc candidates for PyPI packages. You can also
provide both suffixes in case you prepare alpha/beta versions. The packages are prepared in
dist folder. Note that this command also cleans up dist folder before generating the packages
so that you do not have accidental files there. This will delete airflow package if it is
prepared there so make sure you run prepare-provider-packages first,
and prepare-airflow-packages second.
Examples:
'breeze prepare-provider-packages' or
'breeze prepare-provider-packages google' or
'breeze prepare-provider-packages --package-format wheel google' or
'breeze prepare-provider-packages --version-suffix-for-svn rc1 http google amazon' or

Additional actions executed while entering breeze
-d, --db-reset
Resets the database at entry to the environment. It will drop all the tables
and data and recreate the DB from scratch even if 'restart' command was not used.
Combined with 'restart' command it enters the environment in the state that is
ready to start Airflow webserver/scheduler/worker. Without the switch, the database
does not have any tables and you need to run reset db manually.
-i, --integration INTEGRATION
Integration to start during tests - it determines which integrations are started
for integration tests. There can be more than one integration started, or all to
start all integrations. Selected integrations are not saved for future execution.
One of:
cassandra kerberos mongo openldap pinot rabbitmq redis statsd trino all
--init-script INIT_SCRIPT_FILE

--load-default-connections
Include Airflow Default Connections.
****************************************************************************************************
Cleanup options when stopping Airflow
--preserve-volumes
Use this flag if you would like to preserve data volumes from the databases used
by the integrations. By default, those volumes are deleted, so when you run 'stop'
or 'restart' commands you start from scratch, but by using this flag you can
preserve them. If you want to delete those volumes after stopping Breeze, just
run the 'breeze stop' again without this flag.
****************************************************************************************************
