Charts Checklist (built for v0.5.2 charts-build-scripts)

Checkpoint 0: Validate release.yaml

Validation steps:

• Each chart version in release.yaml DOES NOT modify an already released chart. If so, stop and modify the versions so that it releases a net-new chart.
• Each chart version in release.yaml IS exactly 1 more patch version than the last released chart version. If not, stop and modify the versions so that it releases a net-new chart.

Checkpoint 1: Compare contents of assets/ to charts/

Validation steps:

• Running make unzip to regenerate the charts/ from scratch, then git diff to check differences between assets/ and charts/ yields NO differences or innocuous differences.

IMPORTANT: Do not undo these changes for future steps since we want to keep the charts/ that match the current contents of assets!

Checkpoint 2: Compare assets against index.yaml

Validation steps:

• Each chart has ALL required annotations
  • kube-version annotation
  • rancher-version annotation
  • permits-os annotation (indicates Windows and/or Linux)

[github-actions]

Validation steps

• Ensure all container images have repository and tag on the same level to ensure that all container images are included in rancher-images.txt which are used by airgap customers.

  Ex:-
    longhorn-controller:
      repository: rancher/hardened-sriov-cni
      tag: v2.6.3-build20230913
