What does the 'docker ps' command do?

The docker ps command is used to list the running Docker containers on your system. It provides information about each container, including:

• CONTAINER ID: A unique identifier for the container.
• IMAGE: The name of the image from which the container was created.
• COMMAND: The command that is being executed in the container.
• CREATED: The time when the container was created.
• STATUS: The current status of the container (e.g., running, exited).
• PORTS: The ports that are exposed by the container.
• NAMES: The name assigned to the container.

Example:

docker ps

This command will display a table with details of all currently running containers. If you want to see all containers, including those that are stopped, you can use:

docker ps -a
