crictl:tldr:adb23

The command "crictl ps --all" is used to list all the containers, including both running and stopped containers, in a Kubernetes cluster using the CRI (Container Runtime Interface) tool called "crictl".

Here's a breakdown of the command:

• "crictl" is a command-line interface tool that interacts with the container runtime on a Kubernetes node using the CRI.
• "ps" is the command within crictl used to list the containers. It stands for "Process Status" and is similar to the "ps" command in Linux.
• "--all" is a flag that includes all containers in the listing, regardless of their status (running or stopped). By default, crictl only shows running containers, but using the "--all" flag, it includes all containers in the output.

So, running "crictl ps --all" would list all containers, both running and stopped, present in the Kubernetes cluster.
