docker 创建本地镜像服务器

1.docker pull registry //下载registry 镜像,registry 为docker 官方提供的一个镜像,

我们可以用它来创建本地的docker私有仓库。

docker:/root# docker images | grep registry
registry                latest              07d93e41c370        7 weeks ago         422.8 MB

2.docker run -d -p 5000:5000 registry //以registry 镜像启动容器,监听5000端口

-p 左边是宿主机的端口 右边是容器端口  做映射

curl 127.0.0.1:5000

docker:/root# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS                    NAMES

传入私有仓库:

$exec -d --insecure-registry 172.17.42.1:5000 $other_args &>> $logfile &

docker:/root# docker push 172.17.42.1:5000/zjzc-test01
The push refers to a repository [172.17.42.1:5000/zjzc-test01] (len: 1)

查看仓库镜像:
