Steps for Docker to build a private warehouse Harbor

[root@dockerA ~]# yum -y install yum-utils device-mapper-persistent-data lvm2
//Download the dependencies required by the docker-compose tool (you can install it when you deploy the docker environment)
[root@dockerA ~]# curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
//Download the docker-compose tool [root@dockerA ~]# chmod +x /usr/local/bin/docker-compose
[root@dockerA ~]# docker-compose -v      
docker-compose version 1.25.0, build 0a186604
//Check the docker-compose tool version information to ensure that it has been installed successfully

[root@dockerA ~]# wget https://storage.googleapis.com/harbor-releases/release-1.7.0/harbor-offline-installer-v1.7.4.tgz
//Download harbor software package [root@dockerA ~]# tar zxf harbor-offline-installer-v1.7.0.tgz -C /usr/local
[root@dockerA ~]# cd /usr/local/harbor/
[root@dockerA harbor]# vim harbor.cfg 
//Write its configuration file. Other versions end with cfg by default, but this version ends with yml. The file contents are the same hostname=192.168.45.129 //Change it to the local IP address harbor_admin_password: Harbor12345    
//This line already exists, you don't need to fill it out yourself, just remember its username and password, you can modify it if necessary [root@dockerA harbor]# ./install.sh //Execute the installation script 

[root@dockerA harbor]# vim /usr/lib/systemd/system/docker.service 
//Write the docker main configuration file ExecStart=/usr/bin/dockerd --insecure-registry 192.168.45.129
 //Similar to the registry, the port number is not filled in the harbor configuration file, so you can add it here, otherwise an error may occur [root@dockerA harbor]# systemctl daemon-reload 
[root@dockerA harbor]# systemctl restart docker //Restart the docker service [root@dockerA harbor]# pwd
/usr/local/harbor //Note the directory, it must be in this directory [root@dockerA harbor]# docker-compose start
//Use the docker-compose tool to start all containers (because when you restart docker, all containers are closed)
[root@dockerA harbor]# netstat -anpt | grep 80 //Confirm that port 80 is listening on tcp6 0 0 :::80 :::* LISTEN 22871/docker-proxy 

After the warehouse is built, upload the image on the dockerA (harbor) server!
[root@dockerA harbor]# docker login -u admin -p Harbor12345 192.168.45.129

[root@dockerA ~]# docker tag centos:7 192.168.45.129/test/centos:7
//You need to change the image name, test is the name of the warehouse you just created [root@dockerA ~]# docker push 192.168.45.129/test/centos:7
//Upload the image to the test repository of the harbor server

[root@dockerB ~]# vim /usr/lib/systemd/system/docker.service 
//Write the main configuration file of docker 13 ExecStart=/usr/bin/dockerd --insecure-registry 192.168.45.129
