What command would you use to list all running Docker containers?

Using the command "docker ps" provides a clear and concise way to view all currently running Docker containers. This command queries the Docker daemon and returns a list that includes essential information about each running container, such as the container ID, image name, command, creation time, status, ports, and container name.

The simplicity and directness of "docker ps" make it the standard command for monitoring active containers in a Docker environment. It's noteworthy that this command shows only those containers that are currently operational, as opposed to all containers, which can be viewed using "docker ps -a" to include stopped containers as well. This function is crucial for effective container management, allowing users to identify, monitor, and troubleshoot active environments quickly.

Other options do not exist as valid commands within Docker's interface. For instance, "docker list," "docker status," and "docker running" do not provide the required functionality to list running containers and thus would not yield the desired results in a terminal. This reinforces the importance of using the correct command, as Docker operates with a focused set of commands to maintain clarity and efficiency.
