Docker registry私有镜像仓库服务部署案例演示

#拉去 registry 镜像
	[root@docker-server ~]# docker pull registry
#运行 registry 容器
	[root@docker-server ~]# docker run -itd -p 5000:5000 --name="myregistry" -v /registry:/var/lib/registry --restart=always registry:latest

#以 tomcat 镜像为例，给这个镜像添加一个带有私有仓库IP的TAG
	[root@docker-client ~]# docker tag tomcat:latest 192.168.117.131:5000/tomcat:latest
#修改daemon文件并重启docker
	[root@docker-client ~]# vim /etc/docker/daemon.json
	{
	  "registry-mirrors": ["https://3290299n.mirror.aliyuncs.com"],
	  #注：上下两行用 “,” 分割
	  #添加下面的参数即可，docker-server 端IP和端口
	  "insecure-registries": ["192.168.117.131:5000"]
	}
#重启 docker 服务
	[root@docker-client ~]# systemctl restart docker
#推送镜像至私有镜像仓库
	[root@docker-client ~]# docker push 192.168.117.131:5000/tomcat:latest
#验证：查看私有镜像仓库中是否有 192.168.117.131:5000/tomcat:latest 镜像
	[root@docker-client ~]# curl http://192.168.117.131:5000/v2/_catalog 
	{"repositories":["tomcat"]}
#删除 192.168.117.131:5000/tomcat:latest 镜像

#docker-client 删除本地的 192.168.117.131:5000/tomcat:latest 镜像
	[root@docker-client ~]# docker rmi 192.168.117.131:5000/tomcat
#docker-client 查看本机只有一个 tomcat 镜像
	[root@docker-client ~]# docker images

#docker-client 下载192.168.117.131:5000/tomcat 镜像
