To remove a Docker container, you can use the docker rm command followed by the container ID or name:
docker rm <container_id_or_name>
If the container is currently running, you will need to stop it first using the docker stop command.
Additionally, you can use the following command to remove all Docker containers at once:
docker rm $(docker ps -aq)
This will remove all containers, whether they are running or not.
Note that removing a container will also remove any data or state associated with that container unless you have specifically created data-only containers or volumes for that purpose.
Please keep in mind that removing containers irreversibly removes the container and any data within it.
