Kubernetes version 1.25 change log

Kubernetes version 1.25 change log

This version is no longer supported. Update your cluster to a supported version as soon as possible.

Overview

In clusters that run version 1.23 or earlier, the IBM Cloud provider version enables Kubernetes APIs and features that are at beta. Most new beta features are disabled by default. Kubernetes alpha features, which are subject to change, are disabled in all versions. For more information, see the Default service settings for Kubernetes components and the feature gates for each version.

For more information about major, minor, and patch versions and preparation actions between minor versions, see Kubernetes versions.

Check the Security Bulletins on IBM Cloud Status for security vulnerabilities that affect IBM Cloud Kubernetes Service. You can filter the results to view only Kubernetes Cluster security bulletins that are relevant to IBM Cloud Kubernetes Service. Change log entries that address other security vulnerabilities but don't also refer to an IBM security bulletin are for vulnerabilities that are not known to affect IBM Cloud Kubernetes Service in normal usage. If you run privileged containers, run commands on the workers, or execute untrusted code, then you might be at risk.

Some change logs are for worker node fix packs, and apply only to worker nodes. You must apply these patches to ensure security compliance for your worker nodes. These worker node fix packs can be at a higher version than the master because some build fix packs are specific to worker nodes. Other change logs are for master fix packs, and apply only to the cluster master. Master fix packs might not be automatically applied. You can choose to apply them manually. For more information about patch types, see Update types.
