December 2025

12 December 2025

IBM Cloud Kubernetes Service master fix packs.: Master fix packs are applied automatically over the course of several days. You can choose to use the ibmcloud ks cluster master update command yourself without waiting for the update automation to apply the patch. Review the following change logs for your cluster version.; Version 1.34 change log; Version 1.33 change log; Version 1.32 change log; Version 1.31 change log

10 December 2025

New! IBM Cloud Kubernetes Service version 1.34.: You can now create or update clusters to Kubernetes version 1.34. With Kubernetes 1.34, you get the latest stable enhancements from the Kubernetes community as well as enhancements to the IBM Cloud product.
IBM Cloud Kubernetes Service version 1.34 Kubernetes certification: IBM Cloud Kubernetes Service version 1.34 is now Kubernetes certified.
CoreDNS and NodeLocal DNS cache configuration changes in version 1.34 and later: The default DNS cache time in both CoreDNS and NodeLocal DNS configurations has been increased from 30 seconds to 120 seconds. This change applies to the ConfigMap settings for DNS caching. Some users were hitting pDNS (or UDP) traffic limits due to frequent DNS lookups caused by short cache durations. A 30-second cache interval is rarely necessary except for DNS records that change very frequently, for example health-check endpoints. For most workloads, a 120-second default cache provides better performance and reduces unnecessary DNS traffic. Users who require shorter cache times for specific use cases can override this setting. For more information, see Configuring the cluster DNS provider.

IBM Cloud Kubernetes Service version 1.30 Kubernetes certification: IBM Cloud Kubernetes Service version 1.30 is now Kubernetes certified.
Important networking changes for IBM Cloud Kubernetes Service VPC clusters created at version 1.30.: For more information, see the 130 version information and Understanding Secure by Default Cluster VPC Networking.
Important changes to the default cluster provisioning behavior for new VPC clusters beginning with version 1.30.: Beginning with version 1.30, there is a new option available at cluster creation time via the UI, CLI, API, and Terraform. This new option manages outbound traffic protection for the cluster. The default behavior is to have outbound traffic protection enabled, which means new version 1.30 VPC clusters won't have access the public internet by default. If your cluster needs access to the public internet, you must specifically include the option (from the UI, CLI, API, and Terraform) to disable outbound traffic protection. Note that you can also disable outbound traffic protection after your cluster is created. You can also selectively allow outbound traffic as needed after your cluster is created. If you provision clusters via automation, make sure to adjust your automation accordingly.; For more information, see the 1.30 version information, Understanding Secure by Default Cluster VPC Networking, and Managing outbound traffic protection in VPC clusters.
Managing outbound traffic protection in new version 1.30 VPC clusters.: With the introduction of Secure by Default Cluster VPC networking in version 1.30 and later clusters, there are several scenarios where you might need to adjust the security group settings for your clusters to allow outbound traffic to certain resources. For more information, see Managing outbound traffic protection in VPC clusters.
