查看镜像库

[[email protected]_32_161_centos ~]# docker images

镜像标记

标记一个本地镜像为私有仓库版本
此处将docker.io/redis标记为localhost:5000/redis

docker tag docker.io/redis localhost:5000/redis

推送至私有仓库

[[email protected]_32_161_centos ~]# docker push localhost:5000/redis
The push refers to a repository [localhost:5000/redis]
f02e80b7746e: Pushed

从私有仓库拉取镜像

拉取本地私有仓库镜像

docker pull localhost:5000/redis

拉取远程私有仓库镜像

这里选择另外一台装有docker的服务器
首先更改配置文件/etc/docker/daemon.json

{ "insecure-registries":["xxx.xxx.xxx.xxx:5000"] }

xxx.xxx.xxx.xxx替换为远程私有仓库ip

重启docker

systemctl restart docker

拉取镜像

[[email protected]_32_15_centos ~]# docker pull xxx.xxx.xxx.xxx:5000/redis
Using default tag: latest
Trying to pull repository xxx.xxx.xxx.xxx:5000/redis ...
