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

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)
