Question: 1 / 400

Which of the following commands is used to view the list of images on a Docker host?

docker images

The command used to view the list of images on a Docker host is "docker images." This command provides a straightforward overview of the images that are currently stored locally on the Docker host. It displays key information including repository names, tags, image IDs, creation times, and sizes, which is essential for managing and maintaining the images used in container deployments.

The other options do not serve the purpose of listing images. The command "docker list" does not exist in Docker's command set, making it invalid. The command "docker ps -a" is designed for listing all containers, including those that are currently running and those that have stopped, not images. Lastly, "docker show images" does not correspond to any valid Docker command either. Thus, understanding the correct usage of "docker images" is critical for effectively managing Docker images on a host.
