What is the function of the command 'docker network ls'?

The command 'docker network ls' serves the purpose of listing all Docker networks that exist on your system. When executed, it provides a detailed view of the networks available for use, including their names, IDs, and driver types. This command is essential for understanding the networking setup in your Docker environment, allowing users to see which networks are available for connecting containers.

In contrast, creating a new Docker network would be accomplished using a different command, such as 'docker network create.' Similarly, listing all Docker images is achieved with 'docker image ls,' and removing a Docker network is done using 'docker network rm.' The focus of 'docker network ls' specifically relates to the visibility and management of networking resources within Docker.
