Listing Containers

In this step, we will learn how to execute the docker ps command to list all the running containers on the Docker daemon. The command docker ps is used to list the containers that are currently running on the system.

First, let's execute the following command in the terminal:

docker ps

This command should display a list of running containers.

Listing All Containers

In this step, we will extend our knowledge by using the docker ps -a command to list all containers - running and stopped. The docker ps -a command provides a complete view of all containers on the Docker daemon.

Let's execute the following command in the terminal:

docker ps -a

This command should display a list of all containers, both running and stopped.

Summary

In this lab, we have delved into the fundamental Docker skill of listing containers using the docker ps and docker ps -a commands. By mastering these skills, the dragon warrior is now equipped to efficiently manage and monitor the containers within the kingdom's infrastructure. This foundational knowledge will pave the way for further exploration into the realm of Docker container management.
