How can you list all running Docker containers?

To list all running Docker containers, the correct command is "docker ps." This command is specifically designed to show active containers along with their details such as container ID, image name, command running inside the container, creation time, status, ports exposed, and the names assigned to the containers.

The command "docker ps" can also be modified with options to list all containers (including those that are stopped) or to filter the output, but by default, it only shows the containers that are currently running. This utility makes it crucial for monitoring and managing containerized applications effectively.

The other options do not correspond to valid Docker commands for listing running containers. For instance, "docker list," "docker containers," and "docker show" do not exist as standard Docker commands in the command-line interface. Understanding the specific command associated with Docker's functionality is essential for working effectively within Docker's ecosystem.
