Openshift Tektoncd Pipeline

This repository holds Openshift's fork of tektoncd/pipeline with additions and fixes needed only for the OpenShift side of things.

List of releases

How this repository works ?

The master branch holds up-to-date specific openshift files that are necessary for CI setups and maintaining it. This includes:

  • Scripts to create a new release branch from upstream
  • CI setup files
    • operator configuration (for Openshift's CI setup)
    • tests scripts
  • Operator's base configurations

Each release branch holds the upstream code for that release and our openshift's specific files.

CI Setup

For the CI setup, two repositories are of importance:

  • This repository
  • openshift/release which contains the configuration of CI jobs that are run on this repository

All of the following is based on OpenShift’s CI operator configs. General understanding of that mechanism is assumed in the following documentation.

The job manifests for the CI jobs are generated automatically. The basic configuration lives in the /ci-operator/config/openshift/tektoncd-pipeline folder of the openshift/release repository. These files include which version to build against (OCP 4.0 for our recent cases), which images to build (this includes all the images needed to run Knative and also all the images required for running e2e tests) and which command to execute for the CI jobs to run (more on this later).

Before we can create the ci-operator configs mentioned above, we need to make sure there are Dockerfiles for all images that we need (they’ll be referenced by the ci-operator config hence we need to create them first). The generate-dockerfiles.sh script takes care of creating all the Dockerfiles needed automatically. The files now need to be committed to the branch that CI is being setup for.

The basic ci-operator configs mentioned above are generated via the generate-release.sh file in the openshift/tektoncd-pipeline repository. They are generated to alleviate the burden of having to add all possible test images to the manifest manually, which is error prone.

Once the file is generated, it must be committed to the openshift/release repository, as the other manifests linked above. The naming schema is openshift-tektoncd-pipeline-BRANCH.yaml, thus the files existing already correspond to our existing releases and the master branch itself.

After the file has been added to the folder as mentioned above, the job manifests itself will need to be generated as is described in the corresponding ci-operator documentation.

Once all of this is done (Dockerfiles committed, ci-operator config created and job manifests generated) a PR must be opened against openshift/release to include all the ci-operator related files. Once this PR is merged, the CI setup for that branch is active.

Create a new release

Deliverables:

  • Tagged images on quay.io
  • An OLM manifest referencing these images
  • Install documentation

High-level steps for a release

Building upstream

Update the operator

  1. Copy the upstream release manifest to the operator’s deploy/resources directory. All files in this directory will be applied, so remove any old ones.
  2. Update the manifest[s] to replace gcr.io images with quay.io images.
  3. Build/test the operator
  4. Commit the source
  5. export VERSION="vX.Y.Z" # replace X.Y.Z as appropriate 6.. operator-sdk build --docker-build-args "--build-arg version=$VERSION" quay.io/openshift-knative/$OPERATOR_NAME:$VERSION
  6. docker push quay.io/openshift-knative/$OPERATOR_NAME:$VERSION
  7. git tag $VERSION; git push --tags

Update OLM metadata

  1. The following instructions amount to mirroring upstream changes in the OLM manifests beneath openshift/olm in our forks.
  2. Create a new *.clusterserviceversion.yaml for the upstream release. It’s easiest to copy the previous release’s CSV to a new file and update the name, version, and replaces fields, as well as the version of the operator’s image.
  3. Ensure the upstream release’s RBAC policies match what’s in the CSV. Any upstream edits should be carried over.
  4. Mirror any upstream manifest changes to CRD’s in the corresponding *.crd.yaml file.
  5. Update the currentCSV field in the *.package.yaml file.
  6. Regenerate the *.catalogsource.yaml file using the catalog.sh script. For example,
DIR=openshift/olm \
~/src/knative-operators/etc/scripts/catalog.sh \
> openshift/olm/knative-serving.catalogsource.yaml
