Mapping from dockercli to crictl

crictl is a command-line interface for CRI-compatible container runtimes. You can use it to inspect and debug container runtimes and applications on a Kubernetes node. crictl and its source are hosted in the cri-tools repository.

This page provides a reference for mapping common commands for the docker command-line tool into the equivalent commands for crictl.

Mapping from docker CLI to crictl

The exact versions for the mapping table are for docker CLI v1.40 and crictl v1.19.0. This list is not exhaustive. For example, it doesn't include experimental docker CLI commands.
