CI tooling and hacks to improve CI

Generate openshift/release config

  • Add configuration for your repository in config/<file.yaml>
    • If you're adding a new file in config/ directory, add the new file to the make generate-ci command
  • Run make generate-ci ARGS=--remote=<your_remote>
    • For example, make generate-ci [email protected]:pierDipi/release.git
    • If you are using podman, make sure to have export CONTAINER_ENGINE=podman set
  • Create a PR to https://github.com/openshift/release (to be automated)

To generate openshift/release config for a single repository, run the specific task in the Makefile or run individual commands in the Makefile, such as:

go run github.com/openshift-knative/hack/cmd/prowgen --config config/eventing-hyperfoil-benchmark.yaml --remote <your_remote>
# go run github.com/openshift-knative/hack/cmd/prowgen --config config/eventing-hyperfoil-benchmark.yaml --remote [email protected]:aliok/release.git

This generation works this way:

  • openshift/relase is cloned
  • The target repository is cloned
  • The makefile of the target repository is parsed to find the make targets that match the regex in the config/<file.yaml> files
  • For any matches, 2 tests are generated.
    • One for the presubmit (that runs on PRs on the target repository)
    • One for the periodics (that runs regularly)
  • There are also CI job config generated, which use the tests above.
  • If the matching regex is specified in onDemand field, then the presubmit is marked as optional (always_run: false).
  • Individual OpenShift versions can specify generateCustomConfigs: true. The repository configuration should then list custom configurations under customConfigs. The releaseBuildConfiguration key should include at least tests key with the list of tests to be run. For custom configurations, tests are not generated from Makefile targets but rather taken directly from the configuration. The resulting build configuration is then enriched with images, base images, and dependencies for test steps.

Limitations:

  • It is not currently possible to disable periodics per job

Apply Konflux configurations

  1. Follow the instructions to access the Konflux instance at GitLab (VPN required)
  2. Set the kubectl context to use the ocp-serverless workspace 
    kubectl config use-context konflux-ocp-serverless
  3. Run make konflux-apply

Run unit tests

make unit-tests

Updating OpenShift versions

CI configs use specific OpenShift versions. To change the version, you need to update the YAML files in the config/ directory.

When a new OpenShift version is released, wait until the cluster pool for OpenShift CI is available in https://docs.ci.openshift.org/docs/how-tos/cluster-claim/#existing-cluster-pools.

Getting SO branch associated with upstream branch

SO branch follows the product versioning, while midstream branches follows the upstream versioning.

To make the "clone associated SO branch" easier, you can run the sobranch tool as follows:

GO111MODULE=off go get -u github.com/openshift-knative/hack/cmd/sobranch

so_branch=$( $(go env GOPATH)/bin/sobranch --upstream-version "release-1.11") # or "release-v1.11" or "release-1.11" or "v1.11" or "1.11"

git clone --branch $so_branch [email protected]:openshift-knative/serverless-operator.git

Troubleshooting

Git not configured to use GPG signing

error: gpg failed to sign the data
fatal: failed to write commit object

You need to configure GPG signing in your git config. See https://docs.github.com/en/authentication/managing-commit-signature-verification/telling-git-about-your-signing-key#telling-git-about-your-ssh-key.

If you see this error, you need to update your Git to version 2.34 or later.

error: unsupported value for gpg.format: ssh
fatal: bad config variable 'gpg.format' in file '/Users/<you>/.gitconfig'
