How does the 'docker inspect' command provide detailed information about a container or image?

The docker inspect command returns detailed information about a container or image in JSON format. It retrieves metadata such as configuration, network settings, volumes, environment variables, and status. This is achieved by querying Docker's internal API, which stores all information about containers and images.

Example usage:

docker inspect <container_id_or_image_name>

As a result, you will get a structured output with details such as:

• Container ID
• Startup command
• Ports
• Mountable volumes
• Network settings
• Status and start time

This helps in diagnosing and managing containers.
