Definition of Done Checklist

Note

Not all of these items are applicable to all PRs, the author should update this template to only leave the boxes in that are relevant.

Please make sure all these things are done and tick the boxes

• Changes are OpenShift compatible
• All added packages (via microdnf or otherwise) have a comment on why they are added
• Things not downloaded from Red Hat repositories should be mirrored in the Stackable repository and downloaded from there
• All packages should have (if available) signatures/hashes verified
• Add an entry to the CHANGELOG.md file
• Integration tests ran successfully

TIP: Running integration tests with a new product image

The image can be built and uploaded to the kind cluster with the following commands:

boil build <IMAGE> --image-version <RELEASE_VERSION> --strip-architecture --load
kind load docker-image <MANIFEST_URI> --name=<name-of-your-test-cluster>

See the output of boil to retrieve the image manifest URI for <MANIFEST_URI>.

[NickLarsenNZ]

The image builds, but I haven't tested it yet. Feel free to approve though, and I will merge after testing.

Rerunning the failed test hangs on namespace deletion (twice). A bunch of stateful sets seem to get stuck. Worth looking at.

[NickLarsenNZ]

The test does pass, but kuttl deletes the namespace, causing the vector-aggregator to shutdown/delete, and then the vector sidecars hang whiel trying to export remaining logs...

Something for bbq to resolve ;)
See: stackabletech/issues#810

[NickLarsenNZ]

Looks like it happens before this change too, so I will merge.
