Kubernetes Version 1.19 Now Available in IBM Cloud Kubernetes Service

1 min read

We are excited to announce the availability of Kubernetes version 1.19 for your clusters that are running in IBM Cloud Kubernetes Service.

With the Kubernetes service, you can easily upgrade your clusters without the need for deep Kubernetes knowledge. When you deploy new clusters, the default Kubernetes version remains 1.18; you can also choose to immediately deploy version 1.19. Learn more about deploying clusters here.

Kubernetes version 1.19

In addition to all the great Kubernetes features provided in this release, IBM Cloud Kubernetes Service version 1.19 also includes updates to Calico, containerd, CoreDNS, and OLM, several improvements to the key management service (KMS) provider, and enhancements to the cloud provider load balancers. See the IBM Cloud Kubernetes Service version 1.19 changelog for details.

Kubernetes support and updates

IBM Cloud Kubernetes Service now supports the latest three versions of Kubernetes: 1.17, 1.18, and 1.19. Clusters that are running Kubernetes versions 1.15 and earlier are unsupported. Clusters running 1.16 are now deprecated with end of support tentatively scheduled for January 29

It is important to note clusters that run deprecated or unsupported Kubernetes versions may not receive fixes for security vulnerabilities until they are updated to a supported version. Review the potential impact of each Kubernetes version update, and update your clusters today.
