What command is used to list all Docker images on the local machine?

The command to list all Docker images on the local machine is "docker images." This command retrieves and presents a detailed list of the images currently stored on your Docker host. The output includes important information such as the repository name, tag, image ID, and the size of the images.

Understanding how to use this command is crucial for managing your Docker environment, as it allows you to quickly see what images you have available for running containers. This is a foundational aspect of working with Docker, as images serve as the blueprints for creating containers. The other command options presented do not correspond to valid Docker CLI commands for listing images, which reinforces the importance of knowing the correct syntax and available commands within Docker.
