Developers

The project build is straight forward using the Makefile; just doing make should work. Please ensure you have the following installed prior -

  1. GoLang 1.16.x
  2. GCC with deps (required for SQLite driver compilation)

That should be it. Tested on Ubuntu 20.04 with GoLang 1.19.3. One of the development assumption (especially in tests) is no configuration file exists in the box in which test is being executed; which means only default configuration shipped with code is applicable.

Generate Migration script using command as follows from project root -

migrate create -ext sql -dir migration/sqls -seq create_sample_table

For generating mocks we use Mockery. Currently storage and config interfaces are mocked using the tool. Command used for them are -

mockery --all --dir "./config/" --output "./config/mocks"
mockery --all --dir "./storage/" --output "./storage/mocks"

When using the docker-compose please ensure to first start MySQL and then start the broker so that broker finds MySQL on bootup. For example,

docker-compose up -d mysql
# Sleep for 30s
docker-compose up broker
# once up try the following curl -
curl -v localhost:18181/channel/sample-channel/broadcast -X POST -H "X-Broker-Channel-Token: sample-channel-token" -H "X-Broker-Producer-Token: sample-producer-token" -H "X-Broker-Producer-ID: sample-producer" -H "Content-Type: application/json" --data '{"test": "Hello World!"}'
# It wont deliver message anywhere since default sample-consumer's callback URL is invalid

Also note that for testing in docker, you will need the code to be built every time you change code.

Configuration management

If you are intending to work with deployment of Webhook Broker, we recommend you also install the following:

  • Terraform v0.14+
  • Helm - sudo snap install helm --classic
  • kubectl - sudo snap install kubectl --classic
  • AWS IAM Authenticator
sudo curl -o /usr/local/bin/aws-iam-authenticator "https://amazon-eks.s3.us-west-2.amazonaws.com/1.18.9/2020-11-02/bin/linux/amd64/aws-iam-authenticator"
sudo chmod +x /usr/local/bin/aws-iam-authenticator

Release Management

Currently the release is managed through tag pushes and that should be done in 2 PRs. First pull request to update the version for CLI, Main test, Helm docker image tag, Helm package version and Helm app version to set to the new release version, along with any CHANGELOG changes and once this is merged; follow up a tag for this change; that should trigger the release process. Then the second pull request promoting the version to the next dev version.
