在使用docker过程中，往往会用到镜像仓库，方便管理的同时也方便在其他环境下快速下载镜像，本文讲解如何将镜像传入docker官方仓库。操作系统以CentOS 8 为例讲解如何将自己的镜像上传到docker hub。
一、Docker 官网注册一个账号，新建仓库
二、制作镜像，保存修改后的容器镜像为例# 本次不以docker build 为例# docker ps -aEmulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES236cd97f7854 docker.io/oddrationale/docker-shadowsocks:latest -s 0.0.0.0 -p 123... 4 seconds ago Up 3 seconds ago 0.0.0.0:12345->12345/tcp unruffled_hamilton # 拷贝宿主的文件进容器/tmp目录# docker cp /data/shadowsock/config.json 236cd97f7854:/tmp# docker commit 236cd97f7854 shadowsock-feb# docker imagesEmulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.REPOSITORY TAG IMAGE ID CREATED SIZElocalhost/shadowsock-feb latest 55c10922d371 18 hours ago 438 MBdocker.io/oddrationale/docker-shadowsocks latest 4cbc49994ade 3 years ago 438 MB
三、镜像上传# 重新打标签，镜像重命名使之与Docker Hub账号仓库匹配，格式： 用户名/仓库名# docker tag 55c10922d371 skypipi/shadowsockEmulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg. # docker imagesEmulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.REPOSITORY TAG IMAGE ID CREATED SIZElocalhost/shadowsock-feb latest 55c10922d371 18 hours ago 438 MBlocalhost/skypipi/shadowsock latest 55c10922d371 18 hours ago 438 MBdocker.io/oddrationale/docker-shadowsocks latest 4cbc49994ade 3 years ago 438 MB # 指定 docker.io 地址，否则就登录到redhat官网了# docker login docker.ioEmulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.Username: skypipiPassword: Login Succeeded! # docker push skypipi/shadowsockEmulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.Getting image source signatures.......Copying config 55c10922d3 done Writing manifest to image destinationStoring signatures
四、镜像下载 通过官网下载 
通过命令下载 # docker pull skypipi/shadowsock:latest
