1.关闭防火墙

[root@registry ~]# systemctl stop firewalld
[root@registry ~]# systemctl disable firewalld

2.关闭selinux

[root@registry ~]# vi /etc/selinux/config

将 SELINUX=enforcing 修改为 SELINUX=disabled

3.安装docker

二、部署registry

1.下载registry镜像

[root@registry ~]# docker pull registry

2.配置registry信息

[root@master1 v2]# vi /etc/docker/daemon.json

{
"insecure-registries":["192.168.5.128:5000"]
}

重启docker服务

[root@master1 ~]# systemctl restart docker

3.启动registry容器

[root@registry ~]# docker run ‐d ‐p 5000:5000 ‐v /home/registry:/var/lib/registry ‐‐
restart=always ‐‐privileged=true ‐‐name=registry registry:latest

查看registry容器

[root@master1 ~]# docker ps
fb611b773430   registry:latest                                     "/entrypoint.sh /etc…"   About an hour ago   Up About an hour   0.0.0.0:5000->5000/tcp, :::5000->5000/tcp   registry

三、测试验证

1.本地镜像push到私有仓库

[root@master1 ~]# docker images
REPOSITORY                                                        TAG             IMAGE ID       CREATED        SIZE
nginx                                                             latest          d1a364dc548d   3 weeks ago    133MB

2.修改镜像tag

[root@master1 ~]# docker tag nginx:latest 192.168.5.128:5000/nginx:test

3.把修改了tag镜像上传到私有仓库

[root@master1 ~]# docker push 192.168.5.128:5000/nginx:test 
The push refers to repository [192.168.5.128:5000/nginx]

4.查询仓库镜像

[root@master1 ~]# curl http://192.168.5.128:5000/v2/_catalog
{"repositories":["nginx"]}

5.查询仓库里nginx镜像的tag

[root@master1 ~]# curl http://192.168.5.128:5000/v2/nginx/tags/list
{"name":"nginx","tags":["test"]}
