Epic Goal

• Keep MicroShift codebase up to date with upstream OpenShift components (that includes etcd and topolvm)
• Regularly produce RPMs: 4.12 rc, 4.13 nightly, 4.13 engineering candidate

Acceptance Criteria

• Update of OpenShift components matches branching strategy
  • release-4.12 branch should be regularly updated using 4.12 nightlies
  • main branch should be regularly updated using 4.13 nightlies until FF
  • release-4.13 branch will be kept in sync with main automatically until FF, after FF a job for 4.13 branch must be mirrored (from job for main branch)
• Engineering Candidates (EC) based RPM builds are produced
• Nightly and RC RPMs are created for 4.12 and 4.13
• TopoLVM is updated by CI job on a regular interval
• MicroShift's kubernetes components version is 1.26
• Set up a pre-submit job that will verify PRs changing assets, rebase or other scripts with a dry-run (as in no PR will be created) rebase
• Enhance "rebase PR creation"
  • Test the changes upon PR creation - no need to apply "ok-to-test" label
  • If the rebase fails, a PR will be created with relevant information in the description so missing rebases don't go for extended time but are caught early
  • Clean up rebase branches that were closed/merged
  • Post a comment on the PR if the branch is force pushed (newer ushift main branch is rebased using the same nightly build)

Dependencies (internal and external)

• ART
• DPTP (if we have problems/questions related to the CI)

Previous Work:

• USHIFT-4 Define, document and automate MicroShift rebase procedure for nightly images
• USHIFT-137 OCP 4.12 & k8s 1.25 rebase epic
