: The official Kubernetes-incubated CLI tool designed specifically for inspecting and debugging CRI-compliant container runtimes. It provides a runtime-agnostic interface.
: A testing tool used to validate that a container runtime complies with the Kubernetes CRI implementation and handles file systems correctly.
sudo crictl config --set runtime-endpoint=unix:///run/containerd/containerd.sock # Note: If using CRI-O, the socket is usually /run/crio/crio.sock # If using Docker (via cri-dockerd), it is /run/cri-dockerd.sock

: CLI tools specific to containerd. While ctr is a bare-bones development tool for deep file system and image debugging, nerdctl provides a Docker-compatible experience for containerd. Prerequisites
Which you are using (containerd, CRI-O, or Mirantis)? Your target Linux distribution and version?
You can install either the minimal version or the full version (which includes CNI plugins and RootlessKit). For file system management, the minimal version is sufficient.
