Container registry

Container registry is a repository for prebuilt images. Windows Server 2016 maintains a local repository as well. Every time a user tries to install an image it first searches for a local repository and then the public repository. Images can also be stored in a public repository (Docker Hub) or private repository. Base OS images have to be installed first before using any prebuilt images such as MySQL, nginx, and so on. Use docker search to search the repository.
