The first Kubernetes release for 2019 is here! Version 1.14 offers a huge list of new features including major Kubectl updates, Persistent Local Volumes going GA, and much more. Let’s take a look.

Kubernetes’ first release for 2019 brings a lot of goodies!

With 10 features moving to stable, 12 in beta, and 7 brand new, Kubernetes 1.14 is the release with the most enhancements that graduated to stable.

Let’s have a closer look at some of the most interesting highlights of this release.

Extensibility is the goal

Production-level support for Windows nodes – Kubernetes now officially supports adding Windows nodes as worker nodes and scheduling Windows containers, enabling a vast ecosystem of Windows applications to leverage the power of our platform. Here are some of the key features of enabling Windows containers in Kubernetes include:

  • Support for Windows Server 2019 for worker nodes and containers
  • Support for out of tree networking with Azure-CNI, OVN-Kubernetes, and Flannel
  • Improved support for pods, service types, workload controllers, and metrics/quotas to closely match the capabilities offered for Linux containers

Kubectl updates – There are several notable updates for Kubectl including:

  • New Kubectl docs and logo: The documentation for kubectl has been rewritten from the ground up with a focus on managing Resources using declarative Resource Config.
  • Kustomize integration: The declarative Resource Config authoring capabilities of kustomize are now available in kubectl through the -k flag (e.g. for commands like apply, get) and the kustomize subcommand.
  • Kubectl plugin mechanism graduating to stable: Allows developers to publish their own custom kubectl subcommands in the form of standalone binaries.

Persistent local volumes GA – Makes locally attached storage available as a persistent volume source.

PID limiting is moving to beta – Administrators are able to provide pod-to-pod PID isolation by defaulting the number of PIDs per pod as a beta feature. In addition, administrators can enable node-to-pod PID isolation as an alpha feature by reserving a number of allocatable PIDs to user pods via node allocatable.

There are also some more notable updates we should mention:

  • Pod priority and preemption
  • Pod Readiness Gates
  • Harden the default RBAC discovery clusterrolebindings

Head over to the official changelog for the extensive list of new features and updates.
