Attention

• This branch use a new okeanos project called 23ke-ci.

• For testing, please create a new serviceaccount and replace hack/ci/secrets/gardener-kubeconfig.yaml

• Rebase scripts:

  • 00-env should pre-spawn shoots if necessary
  • 01-shoot should choose a shoot and wait for it (both shoot 100% and all hr from main-ks)
  • 02-23ke-bucket
  • 03-23ke-config-bucket
  • 04-23ke -> Refine timings from hr's (eg. cpfl could be installed earlier), find a way to reconcile hr after parent succeded
  • 05-gardenlet
  • 06-microservice -> possibility for matrix build

• Matrix-Build:

  • 3 different k8s versions for gardener installation
  • on the new gardener: 3x2 Shoots with k8s-version x provider
  • pre-spawning?

• Test: Upgrade Gardener

  • If base-install/gardener.yaml has changed -> build old gardener -> test upgrade

The last testrun was unsuccessful, but only due to a timeout in the ordering of nodes in the microservice shoots, some pods where already running and the frontend was reachable(loadbalancer works) willl still merge this PR now :)
