docker搭建本地仓库

操作概览：

• 1, 拉取启动仓库服务的：image文件
• 2, 运行仓库image, 创建容器（能提供服务的仓库）
• 3, 往本地仓库里： pull /push 镜像

1，拉取registry镜像

root@boot2docker:/home/docker# docker pull registry

Using default tag: latest
latest: Pulling from library/registry

046e2d030894: Pull complete

Status: Downloaded newer image for registry:latest

2, 启动本地仓库

root@boot2docker:/home/docker# docker volume create registry
root@boot2docker:/home/docker# docker run -d -p 5000:5000 --name registry -v registry:/var/lib/registry registry

root@boot2docker:/home/docker# docker ps

root@boot2docker:/home/docker# netstat -nltp |grep 5000
tcp        0      0 :::5000                 :::*                    LISTEN      3954/docker-proxy

3, 在本地仓库里： push镜像

root@boot2docker:/home/docker# docker tag  sath89/oracle-11g  localhost:5000/oracle-11g
root@boot2docker:/home/docker# docker push  localhost:5000/oracle-11g

The push refers to repository [localhost:5000/oracle-11g]

#查看仓库里的镜像
root@boot2docker:/home/docker# curl -X GET localhost:5000/v2/_catalog
{"repositories":["oracle-11g"]}

4, 在别的机器上： 拉取本地仓库的镜像

# 1，添加仓库地址
[root@centos7 ~]# echo '{ "insecure-registries":["192.168.226.138:5000"] }' > /etc/docker/daemon.json
[root@centos7 ~]# systemctl restart docker

#2，拉取本地仓库的镜像
[root@centos7 ~]#  docker pull 192.168.226.138:5000/oracle-11g                                             Using default tag: latest
latest: Pulling from oracle-11g

Status: Downloaded newer image for 192.168.226.138:5000/oracle-11g:latest

# 3， 查看结果
[root@centos7 ~]# docker images
