container application is more and more widely used, the advantages of container technology is the development of operation and maintenance integration. By encapsulating the application and its dependent packages, operating system files and so on in the container image, the application has the same operating environment in the development, testing and publishing process, which brings great convenience. As you can see from the classic

A container is an instance of mirroring, a prelude mirror, and then a container, so the container can have more than one.Although DockerHub provides a large number of mirrors, not every application can find a corresponding image to use in DockerHub due to the diversity of the enterprise environment.

build an enterprise-private mirrored warehouse that meets push and pull mirroring from the development environment . When we use k8s to orchestrate and dispatch containers, the basic unit of the operation is mirroring, so we need to pull the mirror from the repository to the current working node.
