五、Docker构建私有registry

1.启动registry

docker run -d -p 5000:5000 --restart=always --name registry -v /opt/registry:/var/lib/registry  registry

2.修改配置文件

vim /etc/docker/daemon.json
{
  "registry-mirrors": ["https://68rmyzg7.mirror.aliyuncs.com"],
   "insecure-registries": ["10.0.0.100:5000"]
}

[root@docker docker]# systemctl  restart docker

3.制作本地镜像并push

[root@docker ~]# docker tag nginx 10.0.0.100:5000/maxzhu/nginx:v1
[root@docker ~]# docker images
[root@docker ~]# docker push 10.0.0.100:5000/maxzhu/nginx:v1

4. 异地进行pull镜像

[root@docker ~]# docker pull  10.0.0.100:5000/maxzhu/nginx:v1

5.本地仓库加安全认证并重新启动

生成密码:
yum install httpd-tools -y
mkdir /opt/registry-auth/ -p
htpasswd  -Bbn oldguo 123 > /opt/registry-auth/htpasswd
docker rm -f `docker ps -aq`
docker run -d -p 5000:5000 -v /opt/registry-auth/:/auth/ -v /opt/registry:/var/lib/registry  --name register-auth -e "REGISTRY_AUTH=htpasswd" -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" -e "REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd" registry
