1.26.5-gke.1200

Kubernetes OSS release notes

1.26.4-gke.2200

Kubernetes OSS release notes

• Bug Fixes

  • Fixed an issue where Kubernetes would incorrectly apply the default StorageClass to PersistentVolumeClaims which have the deprecated annotation volume.beta.kubernetes.io/storage-class.
  • Fixed an issue in which the logging agent consumed increasingly high amounts of memory.

• Security Fixes

  • Fixed CVE-2023-1872.
  • Fixed an issue affecting netfilter connection tracking (conntrack), which is responsible for monitoring network connections. The fix ensures proper insertion of new connections into the conntrack table and overcomes the limitations caused by changes made to Linux kernel versions 5.15 and higher.

1.26.2-gke.1001

Kubernetes OSS release notes

• Known Issue: Kubernetes 1.26.2 will incorrectly apply the default StorageClass to PersistentVolumeClaims which have the deprecated annotation volume.beta.kubernetes.io/storage-class.

• Feature: Updated OS image to Ubuntu 22.04. cgroupv2 is now used as the default control group configuration.

  • Ubuntu 22.04 uses cgroupv2 by default. We recommend that you check if any of your applications access the cgroup filesystem. If they do, they must be updated to use cgroupv2. Some example applications that might require updates to ensure compatibility with cgroupv2 are:
  • Third-party monitoring and security agents that depend on the cgroup filesystem.
  • If cAdvisor is being used as a stand-alone DaemonSet for monitoring Pods and containers, it should be updated to version v0.43.0 or later.
  • If you are using JDK, we recommend that you use version 11.0.16 and later, or version 15 and later. These versions fully support cgroupv2.
  • If you are using the uber-go/automaxprocs package, make sure to use version v1.5.1 or higher.
  • For more information, see the Ubuntu release notes

• Feature: Sends metrics for control plane components to Cloud Monitoring. This includes a subset of the Prometheus metrics from kube-apiserver, etcd, kube-scheduler, kube-controller-manager. Metrics names use the prefix kubernetes.io/anthos/.

• Feature: Enabled sending Kubernetes resource metadata to Google Cloud Platform, improving both the user interface and cluster metrics. For the metadata to be ingested properly, customers need to enable the Config Monitoring for Ops API. This API can be enabled either in the Google Cloud Console , or by manually enabling the opsconfigmonitoring.googleapis.com API in the gcloud CLI. Additionally, customers must follow the steps outlined in the Authorize Cloud Logging/Monitoring documentation to add the necessary IAM bindings. If applicable, add opsconfigmonitoring.googleapis.com to your Proxy Allowlist.

• Feature: Enabled kubelet graceful node shutdown. Non-system Pods are given 15 seconds to terminate, after which system Pods (with the system-cluster-critical or system-node-critical priority classes) have 15 seconds to gracefully terminate.

• Feature: Enabled Node auto repair feature in preview mode. Please contact your account team to opt into the preview.

• Bug Fixes: Newly-created clusters now use etcd v3.4.21 for improved stability. Existing clusters of previous versions were already using etcd v3.5.x and will not be downgraded to v3.4.21 during cluster upgrade; these clusters will instead use v3.5.6.

• Security Fixes:

  • Fixed CVE-2023-0461.

1.25.5-gke.1500

Kubernetes OSS release notes

• Known Issue: Some UI surfaces in Google Cloud console can't authorize to the cluster and might display the cluster as unreachable. A workaround is to manually apply RBAC permitting user impersonation. For details, see Troubleshooting.

• Security Fixes

  • Fixed CVE-2022-23471
  • Fixed CVE-2021-46848
  • Fixed CVE-2022-42898

1.25.4-gke.1300

Kubernetes OSS release notes

• Known Issue: Some UI surfaces in Google Cloud console can't authorize to the cluster and might display the cluster as unreachable. A workaround is to manually apply RBAC permitting user impersonation. For details, see Troubleshooting.

• Deprecation: Removed deprecated in-tree volume plugins flocker, quobyte and storageos.

• Feature: Uploading of workload metrics using Google Managed Service for Prometheus with managed collection to Cloud Monarch is now available in GA.

• Feature: Enhanced security by restricted static pods running on the cluster's control plane VMs to run as non-root Linux users.

• Feature: Azure AD GA. This feature allows cluster admins to configure RBAC policies based on Azure AD groups for authorization in clusters. This supports retrieval of groups information for users belonging to more than 200 groups, thus overcoming a limitation of regular OIDC configured with Azure AD as the identity provider.

• Feature: Added a new token manager (gke-token-manager) to generate tokens for control plane components, using the service account signing key. Benefits:

  1. Eliminate the dependency on kube-apiserver for control plane components to authenticate to Google services. Previously, control plane components would use the TokenRequest API and were reliant on a healthy kube-apiserver. Whereas now the gke-token-manager component mints the tokens directly using the service account signing key.
  2. Eliminate the RBAC for generating token for controlplane components.
  3. Uncouple the logging and kube-apiserver. So that the logging can be ingested before the kube-apiserver is up.
  4. Make the controlplane more resilience. When the kube-apiserver is out of service the controlplane components can still get the tokens and keep working.

• Feature: As a preview feature, ingest a variety of metrics from the control plane components to Cloud Monitoring, including kube-apiserver, etcd, kube-scheduler and kube-controller-manager.

• Feature: Users in a Google Group can access Azure clusters using Connect Gateway by granting necessary RBAC permission to the Group. More details at Set up the Connect gateway with Google Groups.

• Bug Fix: Fixed an issue which could result in outdated versions of gke-connect-agent not being removed after cluster upgrades.

1.24.3-gke.2100

Kubernetes OSS release notes

• Feature: Disable profiling endpoint (/debug/pprof) by default in kube-scheduler and kube-controller-manager.
• Feature: Update kube-apiserver and kubelet to only use Strong Cryptographic Ciphers.
• Feature: go1.18 stops accepting certificates signed with the SHA-1 hash algorithm by default. Admission/conversion webhooks or aggregated server endpoints using these insecure certificates will break by default in 1.24. The environment variable GODEBUG=x509sha1=1 is set in Anthos on-Azure clusters as a temporary workaround to let these insecure certificates continue to work. However, the go team is anticipated to remove support on this workaround in the near coming releases. Customers should check and ensure there aren't any admission/conversion webhooks or aggregated server endpoints that are using such insecure certificates before upgrading to the upcoming breaking version.
• Feature: Improve network connectivity checks during cluster and node pool creation to help troubleshooting.
• Feature: Upload Kubernetes resource metrics to Google Cloud Monitoring for Windows node pools.
• Feature: Deploy Daemonset azure-cloud-node-manager with kubelet credentials to complete node initialization.
• Feature: Update kubelet to apply external Azure cloud provider.

• Feature: Upload workload metrics using Google Managed Service for Prometheus to Cloud Monarch is available as invite only private preview.

This supports retrieval of groups information for users belonging to more than 200 groups, thus overcoming a limitation of regular OIDC configured with Azure AD as the identity provider.
