To remove all Docker containers, you can use the docker rm command with appropriate flags. Here's how you can do it:

docker rm $(docker ps -aq)

This command will remove all Docker containers regardless of their state.

Explanation:

• docker ps -aq: This command lists all containers (running and stopped) and outputs only their IDs in a quiet mode.

• docker rm $(docker ps -aq): This command removes all containers listed by docker ps -aq.

Make sure you understand that this command will remove all containers on your system, so use it with caution. If you only want to remove stopped containers, you can use docker container prune:

docker container prune

This command will interactively remove all stopped containers. You will be prompted to confirm the removal.

Additionally, if you want to remove all Docker resources including containers, networks, volumes, and images not associated with a container, you can use:

docker system prune

Again, exercise caution while using this command as it will remove all unused Docker resources.
