By making containerized purposes dramatically simpler to handle at scale, Kubernetes has turn out to be a key a part of the container revolution. Here’s the newest.
Kubernetes 1.22, launched August 5, 2022, comprises the next new and up to date options:
- Server-side Apply is now usually accessible. This beforehand beta-only function permits objects on Kubernetes servers to be created and modified declaratively, by having the developer describe their intent. Changes to an object are tracked on a field-by-field foundation, in order that any makes an attempt to alter a discipline modified and “owned” by another person can be rejected. Server-side Apply is meant ultimately to exchange the unique

- Better help for growing and working on Microsoft Windows. Some Kubernetes options for Windows are nonetheless alpha—e.g., privileged containers—but it surely’s now attainable to run extra of the early-support Kubernetes options on Windows by manually constructing the Windows kubelet and kube-proxy binaries.
Other adjustments in Kubernetes 1.22:
- Nodes can now run on techniques the place swap reminiscence is activated if wanted. Kubernetes admins used to should disable swap area earlier than organising Kubernetes. (Alpha function.)
- Support for default, cluster-wide seccomp profiles is now accessible. (Alpha.)
kubeadmcan now be run as non-root if wanted, by working the management airplane with decrease privileges. (Alpha.) All different Kubernetes node parts may be run experimentally as a non-root person as properly.- Some APIs have been deprecated and adjusted, specifically the API for Ephemeral Containers (which was an alpha function to start with and didn’t have a secure API).
Kubernetes 1.20, launched in December 2020, launched these main adjustments:
