Kubernetes 1.22 has dropped with a whole lot of enhancements (53) which makes it the single largest release to date! The momentum of the k8s project continues to be impressive. Let’s dive into what’s new!
This is the first release in 2 years! In that time etcd advanced to a graduated project and the main focus of development has been around performance, security, and monitoring. With this latest release we see etcd further establish itself as a core building block of Kubernetes and more in the cloud native ecosystem. 🎓
With new releases come new deprecations. Make sure you are prepared and aware of the changes coming down the line. While most of us don’t run the latest and greatest in production, make sure to check this guide for planning.
With PodSecurityPolicies (PSP) being deprecated as of 1.21, this is its intended replacement with a built-in admission controller that enforces the Pod Security Standards. We will be keeping our eye on this as it matures. 👀
We’ve had server-side apply since 1.14, but it’s graduating to a GA feature in 1.22! It's quite a powerful tool that allows for declarative configurations and helps enable a more collaborative k8s experience.
