容器布置好的情况下：
docker pull registry （一般没啥问题）
修改容器的镜像仓库配置【可配置多个】
vim /etc/docker/daemon.json
一般配置：
{
"insecure-registries":["192.168.0.58:5000"]
}
多个镜像库：
{
"registry-mirrors":["https://fy707np5.mirror.aliyuncs.com"],"insecure-registries":["192.168.0.58:5000"]
}
https://fy707np5.mirror.aliyuncs.com 借用别人的阿里加速镜像库
启动：
docker run -d -p 5000:5000 --name rancher-registry docker.io/registry 【rancher-registry随便定义的rancher库】
修改配置后重启
systemctl daemon-reload
自测
curl http://127.0.0.1:5000/v2/_catalog
[root@mayi-3 ~]# curl http://127.0.0.1:5000/v2/_catalog
{"repositories":[]} (空镜像仓库)
功能测试：
拉取：
docker pull hello-world
[root@mayi-3 ~]# docker image ls (查看镜像)
REPOSITORY TAG IMAGE ID CREATED SIZE
rancher/rancher latest ec97968cb7d3 7 days ago 1.12GB
hello-world latest feb5d9fea6a5 4 weeks ago 13.3kB
registry latest b2cb11db9d3d 8 weeks ago 26.2MB
-----------------------------------------------------------------------------------------------------------------------
镜像打标记：（创建镜像不能有大写）
docker tag hello-world:latest 127.0.0.1:5000/hello-world:latest
[root@mayi-3 ~]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
rancher/rancher latest ec97968cb7d3 7 days ago 1.12GB
127.0.0.1:5000/hello-world latest feb5d9fea6a5 （ID相同） 4 weeks ago 13.3kB (打标记的镜像)
hello-world latest feb5d9fea6a5 4 weeks ago 13.3kB
registry latest b2cb11db9d3d 8 weeks ago 26.2MB
-----------------------------------------------------------------------------------------------------------------------
推送到私有镜像仓库：
docker push 127.0.0.1:5000/hello-world:latest
[root@mayi-3 ~]# curl http://127.0.0.1:5000/v2/_catalog
{"repositories":["hello-world"]}
本地打标记一份镜像
[root@mayi-3 registry_auth]# docker tag registry:latest 127.0.0.1:5000/registry:test
[root@mayi-3 registry_auth]# docker image ls
