OpenShift Serverless Functions

This repository holds the OpenShift Serverless fork of knative-sandbox/kn-plugin-func with modifications needed only for OpenShift.

The upstream CLI uses built in "language packs" that use paketo builders and buildpacks. This midstream repository replaces the manifest.yaml files in each of these language pack templates with one containing the Red Hat builder images. These can be found in ./templates.

Mirroring upstream

The upstream repo, knative-sandbox/kn-plugin-func is mirrored on the release-next and release-next-ci branches, as well as all of the existing release branches.

In order for mirroring to work correctly, you'll need to have two git remotes for this repository.

  • upstream pointing to knative-sandbox/kn-plugin-func
  • openshift pointing to openshift-knative/kn-plugin-func

When we are preparing to release a new version of OpenShift Serverless functions we need to mirror the upstream repository and apply the template modifications. This is done using the openshift/release/update-to-head.sh script. When it runs, the following steps are taken.

  • The upstream is fetched and checked out as the release-next branch
  • The openshift remote main branch is pulled and openshift specific files from that branch are applied to the release-next branch
  • The release-next branch is force pushed to the openshift remote
  • The release-next branch is duplicated to release-next-ci
  • A timestamp file is added to release-next-ci branch
  • The release-next-ci branch is force pushed to the openshift remote
  • A pull request is created (if it does not already exist) for this change, in order to trigger a CI run
