Sustainable deployment based on Docker and Jenkins

Solution Process
Install Docker, and initialize the Docker Swarm Management Server cluster to install Jenkins, and deploy it with mananger nodes in Swarm, and install the Docker private mirror server without Docker installation for multiple environments to compile. Because of the problem of file transfer size, it is not recommended to use a reverse proxy, for security reasons, the private mirror server is not allowed to access the extranet. After Jenkins compiles the image, pushes it to the Docker private mirror server, and then creates a Docker service "deleted with the same name" and the invalid image is removed for storage capacity consideration.
