@vdemeester vdemeester released this 23 Jan 11:46
v0.10.0
b23f7d4

🎉 Happy new year release with a lot of gift 🎉

Go modules switch, Enhancements of scripts (no shebang required, Condition support, …), workspace addition, embedded TaskSpec in PipelineSpec, More PodTemplate (and defaults support), Optional and allowing unused PipelineResources.

Note: starting from this release, there will be a release.notags.yaml in addition to the usual release.yaml. This file (release.notags.yaml) is meant to be used if the container runtime used by your kubernetes distribution is not compatible with the image reference notation name:tag@digest (which is currently the case for cri-o and thus for OpenShift 4.x).

Changes

Features

  • ✨ Script enhancements

    Task steps that use script mode no longer need to specify a shebang line. Scripts that do not start with a shebang will use a default value of "#!/bin/sh". (#1691)
    Allow args with script mode (#1656)
    Script mode will now insert set -xe to scripts that don't include a shebang #!, which will in turn fail scripts with commands that error our and also print the command that is about to run. This default behaviour can be disabled by simply specifying your own #! at the top of the script. (#1736)
    Add script mode for Conditions (#1798)

  • ✨ Add workspace support to Task{,Run} and Pipeline{,Run}

    Adds the concept of "workspaces" to Tasks. This allows Task authors to declare directories they expect to be provided via Volumes at runtime. At runtime, TaskRuns can provide PVCs or EmptyDirs to use for these directories. (#1639)
    A Task's workspaces can be declared as readOnly: true. When this is set, the underlying volume mount will likewise be marked as read-only and the task will not be able to write to the volume. (#1760)
    A ConfigMap can be bound to a workspace. This allows users to easily expose the contents of a ConfigMap as a volume in Task containers. (#1800)
    Secrets can now be used for the contents of task workspaces. Users can now more easily declare and expose a secret as a volume for tasks to use in their step containers. (#1801)
    Pipelines and PipelineRuns can now declare workspaces to more easily thread shared storage through the tasks in a pipeline (#1866)

  • ✨ PipelineResource enhancements

    Do not error out in case of extra, unused resource (#1679)
    PullRequestResource: Adds read-only pr.json to include other various pull request information. (#1685)
    Introducing a new key called optional as part of the PipelineResourceDeclaration by default a resource is required (as is - no change in behavior). (#1601)

  • ✨ Adding support for taskSpec with pipelineSpec
    Allow embedding task specification with taskSpec under pipelineSpec (#1554)

  • ✨ Add Go module support for pipelines. (#1607)

  • ✨ PodTemplates enhancements

    Support the automountServiceAccountToken, dnsPolicy, dnsConfig, and enableServiceLinks fields in pod templates (#1781)
    Add support for default pod template (#1901)

  • ✨ Use tekton instead of all as categories 🎿

    Remove the category all for our CRD and have a tekton categorie that is shared with other tektoncd projects (#1884)

  • ✨ Changes to add results to a task

    Add results to the task spec and handle all changes in the entrypoint code. (#1888)

  • ✨ Don't hard-code too much 😝
    The webhook service and deployment can have a name specified by the user. (#1724)
    ConfigMaps used to configure artifact storage can have a name specified by the user (#1723)

  • ✨ Reflect tektoncd/pipeline release version as an annotation on pod
    tekton.dev/release annotation will be added to all pods created by the controller which would let us know what release of tekton is running. (#1758)

  • ✨ Add support for from usage in Pipeline Conditions

    Resources in Pipeline Conditions can now declare that they depend on the output of previous tasks using the from clause. (#1527)

  • ✨ Issue 1182: Add sslVerify flag to pipelineresource type git

    The sslVerify parameter is now available on PipelineResource's of type git. This property defines whether http.sslVerify should be set to true or false in the global git config. Setting the property to false will disable certificate validation during the running of the git fetch against the git server and will be of use to people hosting git servers with self signed certificates. The parameter sslVerify defaults to true if omitted. (#1752)

  • ✨ Add Description to ResourceDeclaration (#1875)

  • ✨ Make default managed-by label configurable

    The default app.kubernetes.io/managed-by label value is configurable in a ConfigMap (#1893)

  • ✨ Add gitlab support to the PR resource. (#1550)

Additionaly there has been ground work on the next API version, v1alpha2:

  • ❇️ Add Task to v1alpha2 🎋 (#1651)
  • ❇️ Port workspace and script without shebang to v1alpha2 (#1841)
  • ❇️ Add TaskRun to v1alpha2 🎋 (#1725)
  • ❇️ Add Pipeline to v1alpha2 🎋 (#1864)

Deprecation Notices

  • 🚨 Removes unused status fields from Pipeline and PipelineResource.

    Those fields stays in v1alpha1 but should be gone in the next API version (#1640, #1762, #1766)

  • 🚨 Don't rely on .status.podName to find Pod associated with a TaskRun

    TaskRuns identify Tekton-owned Pods using label selectors, instead of relying on the value of .status.podName. This valus is still provided in case clients rely on its presence. (#1709)

Backwards incompatible changes

In current release:

  • 🚨 Remove /builder/home mount (#1700)

    Possibly breaking: Remove /builder/home volume mount; users should use the value of $HOME, which points to /tekton/home```

  • 🚨 Reserve /tekton/ paths and "tekton-internal-" volume names

    Reject volune names starting with "tekton-internal-" and volume mounts mounting under /tekton/* -- these are reserved for Tekton internal implementation details. (#1701)

  • 🚨 Remove the support for legacy image output paths.

    Support for the legacy image output path (/builder/home/image-outputs) has been removed. The new location (/workspace/output/) should be used instead. (#1671)

  • 🚨 Remove support for the name parameter to cluster resources.

    Support for the "name" parameter to the cluster resource has been removed. Users should use the standard "name" parameter on the resource object itself instead. (#1672)
