Describes Docker mirroring

In the previous introduction, we knew that mirroring is one of Docker's three components.

Docker needs to have a corresponding mirror locally before running the container, and if the mirror does not exist locally, Docker downloads it from the mirror repository (the default is the warehouse in the Docker Hub public registration server).

This chapter will cover more about mirroring, including:

• Get the image from the warehouse;
• Manage mirrors on local hosts;
• This paper introduces the basic principles of mirror implementation.
