What is the primary use of the docker inspect command?

The docker inspect command is primarily used to retrieve detailed information about Docker containers, images, networks, and volumes in a structured format, usually in JSON. This command provides insights into various properties and configurations, such as CPU limits, memory constraints, environment variables, network settings, and the current state of the container or image.

For example, when executed on a container, docker inspect will return comprehensive details that can help users understand the configuration and operational parameters of that container. This is valuable for troubleshooting, auditing, and when managing containers and images.

The other choices present functionalities that do not accurately describe the role of the docker inspect command. While retrieving the status of a running container is a related task that can be accomplished with other Docker commands, it does not encompass the breadth of insights provided by docker inspect. Removing unused images is performed using a different command, and listing available commands does not relate to obtaining details about existing containers or images.
