The Kubernetes container orchestrator team has announced the release of Kubernetes 1.15; the main themes of this release are "extensibility and continuous improvement". One of the focus areas was on usability and lifecycle stability for clusters: "Work on making Kubernetes installation, upgrade and configuration even more robust has been a major focus for this cycle for SIG Cluster Lifecycle (see our last Community Update). Bug fixes across bare metal tooling and production-ready user stories, such as the high availability use cases have been given priority for 1.15.
kubeadm, the cluster lifecycle building block, continues to receive features and stability work required for bootstrapping production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar kubeadm init and kubeadm join commands to configure and deploy an HA control plane. An entire new test suite has been created specifically for ensuring these features will stay stable over time." More information can be found in the release notes.
