We are excited to announce the availability of Kubernetes v1.14.1 for your clusters that are running in IBM Cloud Kubernetes Service
IBM Cloud Kubernetes Service continues to be the first public managed Kubernetes service to support the latest upstream versions from the community. 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 1.12; you can also choose to immediately deploy version 1.14.
In addition to all the great Kubernetes features provided in this release, the IBM Cloud Kubernetes Service version 1.14.1 also includes the following:
- Calico updated to version 3.6.1
- CoreDNS updated to version 1.3.1, including the addition of a metrics port on the cluster DNS service
- Cluster DNS provider will be migrated from KubeDNS to CoreDNS during upgrade from version 1.13 and earlier clusters
- Kubernetes DNS autoscaler updated to version 1.4.0
- IBM pod security policies updated to support the Kubernetes RunAsGroup feature
- Kubernetes configuration updated for improved stability via SupportPodPidsLimit feature and security via NodeRestriction admission controller
Kubernetes support and updates
IBM Cloud Kubernetes Service now supports the latest four versions of Kubernetes: 1.11, 1.12, 1.13, and 1.14. Clusters that are running Kubernetes versions 1.9 and earlier are unsupported. Clusters running 1.10 are deprecated with end of support scheduled for May 15. Clusters running 1.11 will soon be deprecated with end of support tentatively scheduled for June 27. 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.
