@oliver-goetz10m👨🏻‍🌾 gardener-operator Deploys Extension Resources#10518

No Demo, But Still Worth Celebrating 🎉 ​

  • 🐛 [OPERATOR] When checking whether a Deployment rollout is complete, stale Pods are now ignored and no longer counted. #10548
  • ✨ [OPERATOR] gardenlet now performs garbage collection of stale Pods in all namespaces (except kube-system) in the seed cluster. #10548
  • ✨ [OPERATOR] The TopologySpreadConstraint calculation was improved for workload spread across multiple zones. This especially leads to a more balanced distribution of kube-apiserver and istio replicas in seed clusters. #10608

No Demo, But Still Worth Celebrating 🎉 ​

  • ✨ [OPERATOR] kube-proxy now has a readiness probe so that a Node will only become ready for workloads after kube-proxy was ready at least once. #10407
  • ✨ [OPERATOR] Host spread for shoots with failure tolerance node (.spec.controlPlane.highAvailability.failureTolerance.type) is now accomplished via minDomains. Earlier, this happened at a best effort basis only. If a seed was having less than 3 nodes at the time the control-plane pods were scheduled, the desired pod distribution was not possible. #10400

No Demo, But Still Worth Celebrating 🎉 ​

  • 🪓 [OPERATOR] When the NewWorkerPoolHash feature gate is enabled, the calculation now also rolls worker nodes of Shoots when changing systemReserved in the kubelet configuration. Worker pools are not rolled if the sum of kubeReserved and systemReserved does not change. [...] #10290
  • 🐛 [USER] Fixes a bug preventing shoot clusters with annotation shoot.gardener.cloud/skip-readiness: "true" to be created. #10317
  • ✨ [OPERATOR] The .spec.deployment.vpa field in the seedmanagement.gardener.cloud/v1alpha1.{Gardenlet,ManagedSeed} APIs is deprecated and has no effect anymore. It will be removed in a future version. Now, gardenlet deploys its own VPA as part of the Seed reconciliation (after it ensured the VPA CRD exists). #10299

  • 🪓 [DEPENDENCY] The extensions/pkg/webhook/controlplane/genericmutator.Ensurer#EnsureKubeAPIServerService func is removed. This func was used before the introduction of ManagedIstio/APIServerSNI (when the kube-apiserver Service was of type LoadBalancer) to set cloud provider specific annotations to the Service. [...] #9770
  • ✨ [OPERATOR] A new core.gardener.cloud/v1 API version is introduced which only includes the ControllerDeployment resource for now. The new version of the ControllerDeployment drops the type and providerConfig fields in favor of a well-structured section for helm-based ControllerDeployments. #9771

  • ✨ [OPERATOR] gardener-node-agent no longer watches all Nodes in the cluster but restricts to only the Node it is responsible for (with the help of label/field selectors). This should lead to a significant reduction of network I/O, especially for shoot clusters with many nodes. #9672

  • 🪓 [OPERATOR] The docker CRI is no longer supported for machine images in the CloudProfile. Docker CRI was already not supported for Shoots with Kubernetes versions >= v1.23, so adding this CRI is a no-op currently. Please remove all the usages of docker CRI from your CloudProfiles before upgrading to this version. #9135
  • 🐛 [OPERATOR] A bug has been fixed which was preventing valitail systemd services on shoot workers from starting when the UseGardenerNodeAgent feature gate is enabled. #9149
  • 🐛 [USER] The kube-apiserver deployment is annotated to mark the completion of labeling the resources for encrytion so that this step is not repeated in case the "label removal" step fails and resources are partially without the label. #9147
  • ✨ [OPERATOR] BackupEntrys and Shoots are now labelled with seed.gardener.cloud/<seed-name>=true where <seed-name> is the value of .spec.seedName or .status.seedName. This allows for server-side filtering when watching these resources by leveraging a label selector. #9089
