Docker-based mirror image distribution method, system and device in cluster environment

[0039] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0040] Such as figure 1 A method of image distribution in a docker-based cluster environment is shown, including:

[0041] Use docker to build containers in a cluster environment and package them as images. First, start the container on the development host, and then use the Dockerfile to build the container; package the container as a mirror and perform data persistence. A mirror is a static representation of container content, and a container is a dynamic representation of a static mirror at runtime.

[0042] Identify a docker mirror warehouse in the cluster. In the cluster, it is decided to use a host as the host of the mirror warehouse, and run a container on the host as the Docker mirror warehouse. This allows images to be stored in the mirror repository.

[0043] Share images through docker. If the host in the cluster needs to build a container
