1. 拉取镜像
docker pull registry
2.启动容器
docker run -d -v /docker_registry:/var/lib/registry -p 5000:5000 --name registry --restart=always registry:latest
3.查看容器
docker ps -a
4.通过浏览器访问查看私有仓库镜像
http://127.0.0.1:5000/v2/_catalog
5.编辑私有仓库上传地址
[root@cloud ~]# hostname
aa.bb.cc
[root@cloud ~]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://vy58b67c.mirror.aliyuncs.com"],
"insecure-registries":["aa.bb.cc:5000"]
}
6.重启docker服务，重启registry服务
systemctl restart docker
docker restart registry --启动命令添加自启动了不用执行
1.验证上传镜像到私有仓库
拉取镜像
docker pull hello-world
重命名镜像
docker tag hello-world:latest aa.bb.cc:5000/test:1.0.1
上传到私有仓库
[root@cloud ~]# docker push aa.bb.cc:5000/test:1.0.1
The push refers to repository [aa.bb.cc:5000/test]
9c27e219663c: Pushed
1.0.1: digest: sha256:90659bf80b44ce6be8234e6ff90a1ac34acbeb826903b02cfa0da11c82cbc042 size: 525
4.查看私有仓库镜像
curl http://aa.bb.cc:5000/v2/_catalog
{"repositories":["test"]}
这样就表示成功了
验证从私有仓库拉取镜像
删除原有镜像
docker image rm -f aa.bb.cc:5000/test:1.0.1

查看是否拉取成功
docker images

到此私有仓库配置成功，上传、拉取镜像成功。
涉及到隐私，我把个人电脑名、域名做了修改 aa.bb.cc ，实际中可以随便修改域名。配置好hosts hostname就可以了，外网也可以访问私有仓库的话，要做好5000端口的映射就可以了。
