The latest version of Kubernetes 1.20 introduces the following important changes:
- Kubernetes is transitioning to the Container Runtime Interface (CRI) standard. Instead of Docker, any implementation of the standard, such as containerd, will be used to run containers. For most users, the difference will be inconspicuous — for instance, any existing Docker images will function normally. However, issues may arise regarding resource limitations, logging, or interactions with GPUs and specialized hardware.
- Incoming requests to the kube-apiserver can now be prioritized, allowing the administrator to specify which requests should be handled first.
- The process PID limit is now publicly available. This feature ensures that modules cannot exhaust the number of process identifiers available on the Linux host or interfere with other modules by using too many processes.
