一、搭建docker私有镜像仓库
1.1、运行registry容器
docker run -itd -v /data/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:latest
参数说明
-itd：在容器中打开一个伪终端进行交互操作，并在后台运行；
-v：把宿主机的/data/registry目录绑定 到 容器/var/lib/registry目录(这个目录是registry容器中存放镜像文件的目录)，来实现数据的持久化；
-p：映射端口；访问宿主机的5000端口就访问到registry容器的服务了；
--restart=always：这是重启的策略，假如这个容器异常退出会自动重启容器；
--name registry：创建容器命名为registry，你可以随便命名；
registry:latest：这个是刚才pull下来的镜像；
1.2、测试镜像仓库中所有的镜像
[root@registry ~]# curl http://127.0.0.1:5000/v2/_catalog
{"repositories":[]}
1.3、修改下镜像源并重启docker服务
[root@ansible-server Dockerfile]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"],
"insecure-registries": ["59.47.71.229:5000"]
}
#重启服务
[root@ansible-server Dockerfile]# systemctl restart docker
1.4、下载镜像，并打tag
[root@ansible-server Dockerfile]# docker images

#打tag
[root@ansible-server Dockerfile]# docker tag busybox:latest 59.47.71.229:5000/busybox:v1
#查看镜像
[root@ansible-server Dockerfile]# docker images

#推送到镜像仓库
[root@ansible-server Dockerfile]# docker push 59.47.71.229:5000/busybox:v1
The push refers to repository [59.47.71.229:5000/busybox]
