Which command helps you see active containers?

• A. docker container status
• B. docker ps
• C. docker list containers
• D. docker active

Answer: (B)

The command that helps you see active containers is "docker ps." This command is essential in Docker as it lists all currently running containers, providing important information such as the container ID, image name, command, creation time, status, ports, and the names of the containers. Understanding the output of "docker ps" is useful for monitoring and managing containers effectively. This command allows users to quickly verify which containers are operational, helping with maintenance, troubleshooting, or ensuring that the right services are running as intended. Other options given do not exist as official Docker commands. For example, "docker container status" is not a recognized command and would not return any results. Similarly, "docker list containers" and "docker active" do not correspond to valid Docker commands, which further affirms that "docker ps" is indeed the correct option for viewing active containers.
