🐛 Bug Fixes

[gardener/gardener]

⚠️ Breaking Changes

• [DEVELOPER] The util function pkg/utils/gardener.ComputeShootProjectSecretName has been renamed to pkg/utils/gardener.ComputeShootProjectResourceName. by @​petersutter #9123
• [DEPENDENCY] There are several breaking changes in the github.com/gardener/gardener/extensions/pkg/webhook package:
  • EnsureNoStringWithPrefix, EnsureNoStringWithPrefixContains, EnsureNoEnvVarWithName, EnsureNoVolumeMountWithName, EnsureNoVolumeWithName, EnsureNoContainerWithName, EnsureNoPVCWithName now delete all matching entries. Previously they were deleting only the first occurrence.
  • EnsureStringWithPrefix, EnsureStringWithPrefixContains now act on all prefix matches.
  • StringIndex is removed. instead, use slices.Index. by @​Kostov6 #9007
• [OPERATOR] The UseGardenerNodeAgent feature gate has been promoted to beta and is now turned on by default. by @​rfranzke #9161

📰 Noteworthy

• [USER] The shoot cluster CA bundle is now stored in a ConfigMap in the project namespace of the garden cluster, in addition to storing it in a Secret. This ConfigMap shares the same name as the pre-existing Secret, which is <shoot-name>.ca-cluster. The Secret will be removed in a future Gardener release. Therefore, if your tooling relies on this Secret, you should update it to fetch the ConfigMap instead. by @​petersutter #9123
• [USER] It is now possible to skip a minor Kubernetes version for worker pool Kubernetes version upgrades as long as the version remains equal to or less than the control plane version. by @​shafeeqes #9185
• [OPERATOR] A new field .spec.runtimeCluster.ingress.domains was added to the Garden API. This field allows to use multiple ingress domains for components of the runtime cluster. All domains are assumed to be wildcard domains. Earlier, the API only accepted one domain name via .spec.runtimeCluster.ingress.domain.
  ⚠️ With this change .spec.runtimeCluster.ingress.domain is deprecated and will be removed in the next release. Please update your Garden resource to the new .spec.runtimeCluster.ingress.domains field by removing the existing domain configuration from ingress.domain and add it as the first entry of ingress.domains. by @​ScheererJ #9038

✨ New Features

• [OPERATOR] gardener-resource-manager now considers the health and the progressing status for Prometheus and Alertmanager resources managed via ManagedResources. by @​rfranzke #9163
• [DEVELOPER] It is now possible to provide configuration for the cache Prometheus running in seed clusters' garden namespaces. Read all about it here. by @​rfranzke #9128
• [DEVELOPER] It is now possible to provide configuration for the seed Prometheus running in seed clusters' garden namespaces. Read all about it here. by @​rfranzke #9180
• [DEVELOPER] The WaitUntilObjectReadyWithHealthFunction function was enhanced to log the object's kind. by @​timuthy #9177

🏃 Others

• [OPERATOR] Add Prometheus alert for unhealthy seed node. by @​adenitiu #9127
