1. 无认证私有仓库

1. 拉取镜像， sudo docker pull registry
2. 运行registry容器， sudo docker run -dit --restart always --name registry.me -p 8000:5000 -v /registry.me/registry:/var/lib/registry registry
3. 查看， curl 127.0.0.1:8000/v2/_catalog
4. 修改tag： sudo docker tag redis 192.168.188.131:8000/redis
5. 上传镜像： sudo docker push 192.168.188.131:8000/redis
6. 下载镜像：sudo docker pull 192.168.188.131:8000/redis

问题1： error pulling image configuration: download failed after attempts=6: read tcp 192.168.188.131:40944->104.16.98.215:443: read: connection reset by peer
解决1：
1. vi /etc/docker/daemon.json
2. { "registry-mirrors":[ "https://i1el1i0w.mirror.aliyuncs.com", "https://hub-mirror.c.163.com", "https://registry.aliyuncs.com", "https://registry.docker-cn.com", "https://docker.mirrors.ustc.edu.cn" ] }
3. 重启docker
systemctl daemon-reload
systemctl restart docker
问题2： The push refers to repository [192.168.188.131:8000/redis] Get "https://192.168.188.131:8000/v2/": http: server gave HTTP response to HTTPS client
解决2：

1. vim /etc/docker/daemon.json
2. 加入insecure-registries 如 { "registry-mirrors":[ "https://i1el1i0w.mirror.aliyuncs.com", "https://hub-mirror.c.163.com", "https://registry.aliyuncs.com", "https://registry.docker-cn.com", "https://docker.mirrors.ustc.edu.cn" ], "insecure-registries":["192.168.188.131:8000"] }
3. systemctl daemon-reload
4. systemctl restart docker
