We’re pleased to announce the delivery of Kubernetes 1.13, our fourth and final release of 2018! Kubernetes 1.13 has been one of the shortest releases to date at 10 weeks. This release continues to focus on stability and extensibility of Kubernetes with three major features graduating to general availability this cycle in the areas of Storage and Cluster Lifecycle.
Notable features graduating in this release include: simplified cluster management with kubeadm, Container Storage Interface (CSI), and CoreDNS as the default DNS. These stable graduations are an important milestone for users and operators in terms of setting support expectations. In addition, there’s a continual and steady stream of internal improvements and new alpha features that are made available to the community in this release.
These features are discussed in the “additional notable features” section below. Most people who have gotten hands-on with Kubernetes have at some point been hands-on with kubeadm. It’s an essential tool for managing the cluster lifecycle, from creation to configuration to upgrade; and now kubeadm is officially GA.
kubeadm handles the bootstrapping of production clusters on existing hardware and configuring the core Kubernetes components in a best-practice-manner to providing a secure yet easy joining flow for new nodes and supporting easy upgrades. What’s notable about this GA release are the now graduated advanced features, specifically around pluggability and configurability. The scope of kubeadm is to be a toolbox for both admins and automated, higher-level system and this release is a significant step in that direction.
