How can you rename a Docker container?

Renaming a Docker container can be accomplished using the command docker rename [old_name] [new_name]. This command directly modifies the name of an existing container without the need to stop or restart it.

The command syntax follows a straightforward pattern where the first argument is the current name of the container, and the second argument is the new name you wish to assign. This makes it a simple and effective method for managing container names, especially when you want to clarify the container's purpose or organization.

While other options might imply alternative methods for renaming containers, they do not accurately reflect the correct approach provided in the command. For instance, modifying the Dockerfile primarily pertains to building images rather than renaming running containers, and using the Docker Desktop interface may allow for some graphical management of containers, but it is not the direct method that the command line provides. The option suggesting docker change name is inaccurate since it does not represent a valid Docker command. Therefore, the command docker rename stands out as the correct means to achieve the desired outcome.
