Tekton Pipeline release v0.10.0 "Bombay Robbie"

🎉 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).

-Docs @ v0.10.0
-Examples @ v0.10.0

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)

Fixes

• 🐛 Restrict length of volumes generated from secret names (#1756)
• 🐛 Fix bug in entrypoint lookup for steps by digest (#1675)
• 🐛 Handle injected sidecars more correctly (#1688)
• 🐛 Set scm.PR.Sha to scm.PR.Head.Sha when loading from disk. (#1693)

Tekton Pipeline release v0.9.2

Fix for #1714 and other related issues surrounding the pullrequest resource.

Tekton Pipeline release v0.9.1

Fixes:

• #1675 - Fix bug in entrypoint lookup for steps by digest (Fixes #1674)
• #1685 - Add read-only copy of pull request object in resource output (Fixes #1681)
• #1693 - Set scm.PR.Sha to scm.PR.Head.Sha when loading from disk.

Tekton Pipeline release v0.9.0 "Bengal Bender"

🎉 Script mode, improved pipeline resources, fewer PVCs, more dogfooding and much much more! 🎉

-Docs @ v0.9.0
-Examples @ v0.9.0

Changes

Features

• ✨ Implement step scripts

Support step scripts for easier scripting inside container executions (#1432).

• ✨ Enhance the cluster resource type a bit

Makes it easier to use cluster resource on GKE. (#1466)

• ✨ TaskRunStatus includes sidecar status

The status of a task run includes the image ids of all sidecars. (#1515)

• ✨ git-init: add support for fetching submodules 🚝

git-init (thus GitResource) will now init and update submodules recursively by default (#1531)

• ✨ Migrate PullRequestResource to go-scm.

Updates Pull Request resource to use go-scm. This is the first step towards extending the PullRequest resource to other SCM providers (e.g. GitLab) (#1521)

• ✨ Only make a PVC for a PipelineRun if we need to. 🗑️

PVCs for output -> input linking will now be created only when that linking is actually present in a Pipeline, fixing #937 (used to be created for all Pipelines that included any Task with an Output). (#1545)

Deprecation Notices

• 🚨 Change the path used by the image digest exporter to the standard output path structure.

Image index.json files are now expected to be written to /workspace/output/ instead of /builder/home/image-outputs. The old location is still supported, but support for this will be removed in a future release (#1467).

• 🚨 Remove the custom "name" parameter from cluster resources.

The 'name' parameter to the cluster resource is now deprecated. Please use the standard name parameter on the Task Resource binding instead. (#1474)

• 🚨 Point $HOME to /tekton/home

Change $HOME to /tekton/home
/builder/home is still provided, backed by the same volume, but will be removed in a future release(#1628)

Backwards incompatible changes

In current release:

• 🚨 Remove deprecated serviceAccount field from *Run 🌳

Remove deprecated serviceAccount field from TaskRun/PipelineRun in favor of serviceAccountName.
serviceAccount was deprecated in v0.8.0. serviceAccountName is supported starting v0.8.0 (#1618)

• 🚨 Remove cmd/bash image

This is not strictly speaking an backward incompatible change, since the bash image was not part of the API.
Marking it here in case anyone depend on that image.
Use busybox directly to invoke shell commands in support of internal operations, instead of our own wrapper around busybox. (#1503)

• 🚨 Remove cmd/gsutil image

This is not strictly speaking an backward incompatible change, since the gsutil image was not part of the API.
Marking it here in case anyone depend on that image.
Use google/cloud-sdk directly to invoke gsutil in support of internal operations, instead of our own wrapper around that image. (#1504)

• 🚨 Remove cmd/nop

This is not strictly speaking an backward incompatible change, since the nop image was not part of the API.
Marking it here in case anyone depend on that image.
Use tianon/true instead of cmd/nop (#1510)

• 🚨 Remove outputImageDir from the API

outputImageDir is not supported anymore (#1467)

• 🚨 GCS Resource now requires explicit auth

Users must now call gcloud auth activate-service-account --key-file $GOOGLE_APPLICATION_CREDENTIALS before attempting to use a GCS resource that requires authentication.

Fixes

• 🐛 Have cmd/bash image actually use bash (#1446)
• 🐛 Randomly generate script heredoc to prevent collisions (#1453)
• 🐛 Fix 1059 - TaskRun controller update status and labels on error (#1204)
• 🐛 Replace ValidateFrom with pipelineSpec.Validate (#1452)
• 🐛 Add validation when applying task modifiers 🧐 (#1479)
  • If the implementation of a PipelineResource tries to add steps or volumes that already exist, execution will fail before the pod is created.
• 🐛 Exit with a non-zero exit code when we skip a command in the entrypointer (#1501)
  • Steps now exit with an exit code of 1 if they are skipped because a previous step failed.
• 🐛 Stop race condition on cloud event YAML test (#1517)
• 🐛 Disable colour in tkn logs (#1525)
• 🐛 Re-add support for github auth from the GITHUB_TOKEN env variable. (#1556)

Tekton Pipelines release v0.8.0 "Peterbald Maria"

🎉 Embedded Resource and Pipeline Specs, S3 Artifact Support, Pipeline Metrics & More! 🎉

-Docs @ v0.8.0
-Examples @ v0.8.0

Changes

Features

• ✨ Allow PipelineResource implementations to modify the entire Pod spec.

This change simplifies the interface by removing the GetUpload/Download container and volume methods and replaces it with a more generic "modifier" system. (#1345)

• ✨ Adding support to enable resourceSpec.

Its now possible to embed resourceSpec into PipelineRun. (#1324)

• ✨ Add support for specifiying "0" as no-timeout for PipelineRuns.

This was already done in #1040 for TaskRuns, but PipelineRuns seem to have been missed. (#1365)

• ✨ Add checking insecure flag when creating pipeline resources.

If insecure flag is true, user can create ClusterResource without cadata. (#1354)

• ✨ Resolve all PipelineResources first before continuing

For folks importing the client libraries, when ResourceBindings are instantiated for TaskRuns, they now need to explicitly declare the newly embedded struct PipelineResourceBinding. (#1353)

• ✨ Adding support to enable pipelineSpec

Its now possible to embed the whole pipeline specification into Pipeline Run using pipelineSpec (#1333)

• ✨ Provide a way to specify default service accounts

If pipeline controllers are deployed with a config-map that has default-service-account key set to a non-empty string, pipeline-runs that do not specify a ServiceAccount will be modified (mutated) to the value of the default-service-account. (#1227)

• ✨ Support runtimeClassName in pod templates

This change adds support for the Kubernetes 1.12+ runtime class feature by adding the runtimeClassName field to pod templates and propagating that to the underlying pod spec. (#1363)

• ✨ Add support for using S3-compatible APIs instead of GCS by passing through a boto configuration file.

It is now possible to use S3-compatible APIs instead of GCS for GCS storage resources. (#1361)

• ✨ Update TaskRunStatus.ResourcesResult to be more generic.

  • The Name and Digest fields on TaskRunStatus.ResourcesResult are deprecated and are replaced by the new Key and ResourceRef fields.
  • Both sets of fields are present in this release, but a future release will remove the legacy fields.

• ✨ Add pipeline metrics 🔭 (#1387)

Following Pipelines metrics are available at tekton-pipelines-controller:9090/metrics endpoint

1. Taskrun/Pipeline execution duration time
2. Pipelinerun/Taskrun success and failure duration rates
3. Number of Taskruns and Pipelineruns are executing currently
4. Pod scheduling latency for Taskruns

• ✨ Refactor Resource result output, and add support for Git resources.

The 'Git' PipelineResource now populates the taskRun.status.resourcesResult field with the commit used. (#1424)

• ✨ Support multiple SSH keys for the same host

Allow multiple SSH-auth secrets annotated for the same host (#1433)

Deprecation Notices

• 🚨 The "Name" and "Digest" fields on TaskRunStatus.ResourcesResult are deprecated

The Name and Digest fields on TaskRunStatus.ResourcesResult are deprecated and are replaced by the new Key and ResourceRef fields.

• 🚨 ServiceAccountName(s) replaces ServiceAccount(s)

The serviceAccount field is deprecated. Use serviceAccountName instead.

Tekton Pipelines release v0.7.0 "Lynx Point"

🎉 Nightly Releases, Sidecars for Tasks, CloudEvent pipeline resource, and much much more! 🎉

-Docs @ v0.7.0
-Examples @ v0.7.0

Changes

Features

• ✨ Add nightly release pipeline 🌙.

Nightly build artifacts are available at gs://tekton-release-nightly and gcr.io/tekton-nightly (#1274).

• ✨ Add namespace to cluster resource (#1255).

• ✨ Verify if pipeline works after upgrading from previous release to current release.

This introduces upgrade testing 🎉🎉 (#1162).

• ✨ Allow declaring and passing resources to conditions.

Adds resource support for conditionals. Conditions have to declare the resources they can use and these can be passed in via the Pipeline and PipelineRun spec similar to TaskResources. (#1151)

• ✨ Add sidecars to Tasks

Tasks can now define a list of sidecar containers to run alongside their steps (#1236)

• ✨ Update build-gcs resource type to support .tar.gz archives (#1200)

• ✨ Cloud Event output resource (#837)

New output resource CloudEventPipelineResource available.
When used in a Task, it will generate a cloud event upon completion of any TaskRun
that references that Task. The cloud event includes the entire body of the TaskRun.

Deprecation Notices

• 🚨 Deprecation Notice for Results Field for PipelineRuns and TaskRuns

Adding code comments to bring awareness to Results field removal in v0.8.0 (#1278).

• 🚨 Update build-gcs resource type to support .tar.gz archives

build-gcs resources will no longer support artifactType Archive, use ZipArchive and TarGzArchive instead (#1200)

Backwards incompatible changes

In current release:

• 🚨 Support for ${} syntax removed in favor of $()

${} syntax will no longer perform variable replacement, $() must be used instead. Last release introduced this change in a backwards compatible manner, by supporting both $() and ${}; now we are making the change to remove support for the ${} syntax (#1311).

• 🚨Change the behavior of outputs that are also used as inputs.

Tasks that take input and output resources of the same type must now copy or move the resource from the input directory to the output directory manually. Tekton no longer automatically reads outputs from the input directory when the same resource is supplied in both places (#1122).

• 🚨Remove deprecated podSpec field in favor of podTemplate.

Remove deprecated podSpec (nodeSelector, affinity and tolerations) fields in favor of podTemplate (#1299).

• 🚨Update build-gcs resource type to support .tar.gz archives

build-gcs resources cannot be used as an output resource (#1200)

Tekton Pipelines release v0.6.0 "Toyger Ultron"

🎉 Conditional Execution, Array Params, StepTemplates, and much much more! 🎉

• Docs @ v0.6.0
• Examples @ v0.6.0

Changes

Features

• Pipeline tasks can now be conditionally executed based on a user defined condition. See the docs on how to define Conditions and use then in Pipelines (#1031, #1093, #1143, #1178 ).
  Note: There is more work underway with Conditionals that will be in the next release (tracked in #1137)

• Parameters now support the Array type. See the docs here (#1080).

• stepTemplate now supports variable substitution (#1061)

• The default timeout of TaskRun and PipelineRun is now configurable usingdefault-timeout-minutes in config/config-defaults.yaml (default: 60 mins). The default value can be overridden in a PipelineRun or TaskRun using the timeout field. Setting the timeout to 0 (either in the runs or in the config defaults) means that there will be no timeout for the TaskRun/PipelineRun (#1040).

• TaskRun.Status.Steps.Container now has a ContainerName field (#1100)

• Allow the definition of a storage class for the artifact pvc using the ConfigMap config-artifact-pvc (#1148)

• Tekton now automatically creates directories for each Output resource during a Taskrun (#1156)

• Add a mechanisms to update CRD objects from one version to another (#1083)

• Adds a field called ImageID to TaskRun.Spec.Status.Steps, which contains the full image ID and digest used to run each step (#1026)

• The pullRequest resource type now outputs and expects files in a slightly different format. The new format can be found here (#1181)

Backwards incompatible changes

In current release

• 🚨 Removes containerTemplate which was renamed to stepTemplate 🚨

Last release introduced this change in a backwards compatible manner, now we are making the change to remove containerTemplate(#1174)

• 🚨 Tekton's webhook no longer allows unknown fields in resources 🚨

If you have resources that use fields that were never part of the spec or that have been removed (example: the "trigger" field removed in 0.4.0) then those resources will now fail validation when applied.

Warnings for next release

• 🚨 Please migrate to using podTemplate instead of using Affinity, Tolerations, and NodeSelector 🚨
  TaskRuns and PipelineRuns now contain a PodTemplate field and the Affinity, Tolerations, and NodeSelector fields are deprecated and will be removed in the next release (#1004, #1070)

• 🚨First step in changing ${} syntax to $() 🚨
  Adds support for $() syntax in addition to ${}; in #1170 we will remove support for ${}. Please migrate to $()! (#1172)

• 🚨 Outputs must be placed into the /workspace/outputs directory and Tekton will no longer copy them from the input directory automatically.🚨
  We now warn when the same resource is used as an input and an output of the same Task. This will still be a supported case, but the behavior on where files are expected to be will change in a future release (#1119)

Fixes

• Fix flaky unit tests (#1072)
• Fix Pipeline Spec validation by actually calling the Validate function (#1074)
• ClusterTasks are not validated by the webhook just like any other resource (#1082)
• Unknown fields in resource YAML/JSON will now be rejected when running "kubectl apply" (#1081)
• Fix controller panic on when a TaskRun's Timeout is nil (#1085)
• Validate TaskSpec's that are embedded in a TaskRun (#1084)
• Faster integration tests by switching to Kaniko Dockerfile for image digest exporter tests (#1141)
• Fixes a bug that allowed Tekton Tasks to run steps with a stale entrypoint (#1158)
• PR filenames are URL-escaped before being written to disk (#1195).

Misc

• Reduce the number of imageDigestExporter step to one per Task instead of one for each steps in a Task (#1126)
• Propagate Pipeline labels to Pipeline as soon as possible, so that they are applied even if there is early validation error during reconcile (#1168)
• Changes the type of the Steps field to a type that embeds Container, instead of using the Container type directly (#1060)
