Brief introduction

Docker-registry is an official tool that can be used to build a private image repository, which is created under the / var/lib/registry directory (the directory in the container) by default.

Registry case demonstration environment prepares hostname service IPdocker-client client (for uploading images) 192.168.117.130docker-server server (for storing images) 192.168.117.131 service deployment

Docker-server runs the registry container

# pull registry Image [root@docker-server ~] # docker pull registry# run registry Container [root@docker-server] # docker run-itd-p 5000Groupe 5000-- name= "myregistry"-v / registry:/var/lib/registry-- restart=always registry:latest be25cf74af26f017ea2e6398c9265db584e952211460b9582f54c79f5fdd1938# View Container [root@docker-server ~] # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES be25cf74af26 registry:latest "/ entrypoint.sh / etc..." 37 seconds ago Up 37 seconds 0.0.0.0 5000/tcp myregistry 5000->

Docker-client pushes images to docker-server image repository

# take tomcat image as an example Add a TAG with private repository IP to this image [root@docker-client ~] # docker tag tomcat:latest 192.168.117.131:5000/tomcat:latest# modify the daemon file and restart docker [root@docker-client ~] # vim / etc/docker/daemon.json {"registry-mirrors": ["https://3290299n.mirror.aliyuncs.com"], # Note: use the upper and lower lines" "Segmentation # just add the following parameters Docker-server IP and port "insecure-registries": ["192.168.117.131 docker 5000"]} # restart docker service [root@docker-client ~] # systemctl restart docker# push image to private image repository [root@docker-client ~] # docker push 192.168.117.131:5000/tomcat:latest# verification: check whether there is 192.168 in the private image repository. 117.131:5000/tomcat:latest image [root@docker-client ~] # curl http://192.168.117.131:5000/v2/_catalog {"repositories": ["tomcat"]} # Delete 192.168.117.131:5000/tomcat:latest image

Docker-client downloads image 192.168.117.131:5000/tomcat:latest from private image repository
