Description

Following the decision in stackabletech/issues#767, this PR splits the testing tools into multiple sub images.

There now is a base testing-tools image and specialized images for Trino, Hive and NiFi. Also, Keycloak and Java were removed, since I could not find any evidence of them being used anywhere.

I ran the smoke-latest tests for Hive, Trino, NiFi and OPA plus the kerberos-hdfs test with Hive 4.0.1. Every test run used the new image (or the according sub image accordingly), all tests succeeded.

This PR also bumps the version from 0.2.0 to 0.3.0 so existing tests and demos won't break. We can bump them one by one and see if they still work (my initial tests worked fine, as mentioned before). If anything breaks we can adapt the testing-tools image.

The testing-tools image now has 366MB instead of the 1.25GB it had before. The sub image for Trino/Hive/NiFi also are around 400MB in size.

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

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>.
