Detailed explanation of the construction and interface management of Docker private warehouse

docker search registry # It is recommended to search first, you can look at the related images, maybe there will be better images someday docker pull registry # You don’t need to add a tag, because the latest one is v2

docker run -d \ # Run in the background --name registry-srv \ # Specify the container name --restart=always \ # Set automatic startup -p 5000:5000 \ # Port mapping host, access through the host address -v /opt/zwx-registry:/var/lib/registry \ # Mount the image storage directory locally for easy management and persistence -v /opt/zwx-registry/srv-config.yml:/etc/docker/registry/config.yml \ # Mount the configuration file locally to facilitate modification and saving of registry
