Update gardener-controlplane to 1.69.0

[gardener]

⚠️ Breaking Changes​

  • [OPERATOR] Seed and ManagedSeed API validation has been enhanced by the following checks: (gardener/gardener#7695, @timuthy)
    • (a) New ManagedSeeds can only use the very same zone(s) (managedSeed.spec.gardenlet.config.seedConfig.spec.provider.zones) that are available in the referenced Shoot (shoot.spec.provider.workers[].zones).
    • (b) Existing ManagedSeeds can only add additional zones that are available in the referenced shoot.
    • (c) Removing elements in seed.spec.provider.zones is denied if shoots are still scheduled to the affected seed.
    • These restrictions were removed in Gardener v1.60 to compensate a zone mismatch issue in Azure that is in the meantime fixed by the Azure provider extension v1.34.
    • ⚠️ Before upgrading to this Gardener version, please make sure to check existing ManagedSeed objects. They should configure as many as zone as there are available in the referenced shoot - see check (c).
  • [OPERATOR] gardenlet now cleans up VolumeSnapshot and VolumeSnapshotContent resources from the v1 API of the snapshot.storage.k8s.io group. v1 is served starting external-snapshotter@v4. Before upgrading to this version of Gardener make sure that provider extension install at least external-snapshotter@v4 and do not install any lower version. (gardener/gardener#7759, @ialidzhikov)

✨ New Features​

  • [OPERATOR] Annotations in GardenletConfiguration.seedConfig.metadata.annotations are added to the Seed object during registration. If an annotation is removed from seedConfig, it is not removed from the Seed object. (gardener/gardener#7753, @timebertt)
  • [OPERATOR] It is now possible to perform control plane migration for HA shoot clusters. (gardener/gardener#7626, @plkokanov)
  • [DEVELOPER] Gardener's local setup now supports bootstrapping a Seed with IPv6 single-stack networking using make gardener-up IPFAMILY=ipv6. See the documentation for more detailed steps. (gardener/gardener#7561, @breuerfelix)
  • [DEVELOPER] Developers can now use make gardener-debug to start a skaffold-based debugging loop which allows remote debugging of Gardener Core pods using Delve. See the documentation for more details. (gardener/gardener#7755, @oliver-goetz)
  • [DEVELOPER] generate-controller-registration.sh now supports extension charts with fully-qualified image values instead of the usual image stanza with values for repository and tag. With this, skaffold can be configured (using resourceSelector) to inject a freshly-built image reference into the generated ControllerDeployment. (gardener/gardener#7757, @timebertt)

🐛 Bug Fixes​

  • [OPERATOR] An issue causing the garden/grafana Pod to fail to reach to the garden/loki Pod on cilium Seed clusters is now mitigated. (gardener/gardener#7766, @Kristian-ZH)
  • [OPERATOR] An issue causing state-metrics-seed status to show down falsely has been fixed. (gardener/gardener#7771, @acumino)
  • [OPERATOR] An issue causing the "cache" Prometheus in the (managed) seed's garden namespace to fail when scraping the node-exporter-s in the kube-system namespace has been fixed. (gardener/gardener#7772, @istvanballok)
  • [OPERATOR] A bug in grafana dashboards checking kube-apiserver job for kube-controller-manager up status is now fixed. (gardener/gardener#7773, @shafeeqes)
  • [OPERATOR] Fixed potential leaks of ShootStates that could happen when a Shoot cluster is deleted. This is achieved by no longer exiting early from the deletion flow if the shoot's seed Namespace has been deleted. The same logic has been applied to the migration flow for consistency. (gardener/gardener#7789, @plkokanov)
  • [OPERATOR] A bug causing kube-controller-manager to fail to clean up ShootState resources is now fixed. (gardener/gardener#7793, @shafeeqes)

🏃 Others​

  • [OPERATOR] The .spec.settings.ownerChecks field of the Seed configuration is deprecated. The "bad-case" control plane migration is being removed in favor of the HA Shoot control planes (see https://github.com/gardener/gardener/issues/6302). The field will be locked to false in a future version of Gardener. In this way gardenlet will clean up all owner DNSRecords. Finally, the field will be removed from the API. Set this field to false to be prepared for the above-mentioned locking. (gardener/gardener#7748, @dimitar-kostadinov)
  • [OPERATOR] The SeedChange and CopyEtcdBackupsDuringControlPlaneMigration feature gates have been promoted to GA and are now locked to true. (gardener/gardener#7763, @plkokanov)
  • [OPERATOR] The nested kubelet in the Gardener e2e tests (in prow/kind) now work on hosts using cgroupsv2 (gardener/gardener#7780, @danielfoehrKn)
  • [OPERATOR] The following images are updated: (gardener/gardener#7787, @elankath)
    • eu.gcr.io/gardener-project/gardener/autoscaler/cluster-autoscaler: v1.21.4 -> v1.21.5 (for Kubernetes 1.21)
    • eu.gcr.io/gardener-project/gardener/autoscaler/cluster-autoscaler: v1.22.4 -> v1.22.5 (for Kubernetes 1.22)
    • eu.gcr.io/gardener-project/gardener/autoscaler/cluster-autoscaler: v1.23.2 -> v1.22.3 (for Kubernetes 1.23)

  • [DEVELOPER] The logging integration test is now switched from the loki Service to logging Service. (gardener/gardener#7778, @vlvasilev)
  • [DEVELOPER] Set cgroupDriver of provider-local to systemd. (gardener/gardener#7797, @oliver-goetz)
