centos7上搭建docker私有仓库

来源：互联网发布：release 变量被优化编辑：程序博客网时间：2024/06/06 00:58

私有仓库主机(centos7)：10.60.34.46
客户机(centos7)：client

私有仓库主机上：

下载registry镜像
```
docker pull registry
```
运行registry容器，为了在容器关闭时不删除仓库目录，需要把仓库目录挂载到宿主机目录
```
docker run -d -p 5000:5000 -v /opt/data/registry:/tmp/registry registry
```

客户机上：

获取一个小的镜像busybox用于测试
```
docker pull busybox
```
修改busybox的标签，用于上传到私有仓库
```
docker tag busybox 10.60.34.46:5000/busybox
```

上传

docker push 10.60.34.46:5000/busybox

这里会出现错误：

Error response from daemon: unable to ping registry endpoint https://10.60.34.46:5000/v0/v2 ping attempt failed with error: Get https://10.60.34.46:5000/v2/: EOF v1 ping attempt failed with error: Get https://10.60.34.46:5000/v1/_ping: EOF

原因是与私有仓库的默认交互方式是https，而私有仓库主机只提供http服务。可以在客户端docker的启动配置文件中加入参数：-–insecure-registry=10.60.34.46:5000来规避这个问题。

vi /usr/lib/systemd/system/docker.service

[Service]Type=notifyExecStart=/usr/bin/docker daemon -H fd:// --insecure-registry=10.60.34.46:5000

重启docker：

systemctl daemon-reloadservice docker restart

再次上传：

[root@bogon ~]# docker push 10.60.34.46:5000/busyboxThe push refers to a repository [10.60.34.46:5000/busybox] (len: 1)Sending image listPushing repository 10.60.34.46:5000/busybox (1 tags)Image cfa753dfea5e already pushed, skippingImage d7057cb02084 already pushed, skippingPushing tag for rev [d7057cb02084] on {http://10.60.34.46:5000/v1/repositories/busybox/tags/latest}

查看私有仓库：

[root@bogon ~]# curl http://10.60.34.46:5000/v1/search{"num_results": 2, "query": "", "results": [{"description": "", "name": "library/centos"}, {"description": "", "name": "library/busybox"}]}

查询镜像：

[root@bogon ~]# curl http://10.60.34.46:5000/v1/search?q=busybox{"num_results": 1, "query": "busybox", "results": [{"description": "", "name": "library/busybox"}]}

获取镜像：

docker pull 10.60.34.46:5000/busybox
