阿里云搭建docker私有仓库

云主机操作

启动docker本地镜像服务

推送镜像到本地镜像服务的仓库

云主机安全组

内网主机操作

阿里云主机是99元/年，连续了2年，顺手搭建docker私有仓库，如果docker.io无法下载通过公有云在阿里云私有仓库中转镜像下载；

云主机操作

启动docker本地镜像服务

bash 复制代码

# 拉取registry镜像
[root@iZ2zedkjb5705wlv5ipiqgZ docker-files]# docker pull registry

推送镜像到本地镜像服务的仓库

bash 复制代码

# 本地首先有redis，然后重新tag到本地镜像服务的仓库中
[root@iZ2zedkjb5705wlv5ipiqgZ registry]# docker tag redis:5 127.0.0.1:5000/redis:5

# 推送到本地镜像仓库
[root@iZ2zedkjb5705wlv5ipiqgZ registry]# docker push 127.0.0.1:5000/redis:5

# 如果不重新tag直接推会报错
[root@iZ2zedkjb5705wlv5ipiqgZ registry]# docker push docker.io/mysql:8
Error response from daemon: You cannot push a "root" repository. Please rename your repository to docker.io/<user>/<repo> (ex: docker.io/<user>/mysql)

[root@iZ2zedkjb5705wlv5ipiqgZ registry]# docker push mysql:8
Error response from daemon: You cannot push a "root" repository. Please rename your repository to docker.io/<user>/<repo> (ex: docker.io/<user>/mysql)

云主机安全组

内网主机只要放开跟阿里云的端口服务即可，确保阿里云主机的安全组规则开放了 5000 端口（Docker 镜像仓库默认使用的端口），以便其他物理机能够访问；

内网主机操作

内网主机只要放开跟阿里云的端口服务即可，telnet ip:5000测试ok；

bash 复制代码

以上就完成了使用阿里云主机简单搭建私有仓库镜像仓库，可以先把需要的镜像下载到阿里云后中转下载；
