Which command would you use to view current running Docker containers?

To view currently running Docker containers, the appropriate command is docker ps. This command provides a listing of all active containers on the Docker host at that moment. It displays essential information such as the container ID, image name, command, creation time, status, ports, and the container name itself.

Using docker ps is fundamental for container management, as it allows users to monitor which containers are active and check their health and status. This command can also be supplemented with various flags; for example, adding the -a flag will show all containers, including those that are stopped, whereas just docker ps lists only those that are running.

The other commands listed do not serve the purpose of listing running containers specifically. For instance, docker ls is not a valid command in Docker; there may be confusion with other tools or commands. docker run is used to create and start a new container based on a specified image, and docker containers is not a command in the Docker CLI. Therefore, the use of docker ps is the correct method for observing the current state of running containers.
