Hi,

The session was not recorded, but we had a very brief discussion about command line interfaces for container runtimes, highlighting crictl - a CLI tool for CRI-compatible runtimes such as CRI-O, containerd, and Docker.

After switching the container runtime on a Kubernetes cluster from Docker to containerd, the obvious concern is the user's capability to interact with the runtime for troubleshooting purposes. Crictl is a powerful tool that allows users to interface with high-level container runtimes such as CRI-O and containerd, and even with Docker in addition to the already popular docker CLI.

The crictl documentation presents installation, configuration, and usage instructions:
