Mapping from dockercli to crictl (Life after docker is 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.
Note: The output format of crictl
is similar to docker
CLI, despite some missing columns for some CLI. Make sure to check output for the specific command if your command output is being parsed programmatically.
