自定义私有仓库流程

1. 下载registry镜像

[root@test ~]# docker pull registry
Using default tag: latest
latest: Pulling from library/registry
c87736221ed0: Pull complete 
1cc8e0bb44df: Pull complete 
54d33bcb37f5: Pull complete 
e8afc091c171: Pull complete 
b4541f6d3db6: Pull complete 
Digest: sha256:8004747f1e8cd820a148fb7499d71a76d45ff66bac6a29129bfdbfdc0154d146
Status: Downloaded newer image for registry:latest

2. 修改配置文件daemon.json，并重启docker服务

默认是没有该文件的，需要自己创建
    vim /etc/docker/daemon.json
    {"insecure-registries":["172.24.40.174:5000"]}
重启服务
    systemctl restart docker

3. 启动私有仓库

[root@test ~]# docker run -d -p 5000:5000 registry    //5000:5000 第一个5000是物理机5000端口，第二个5000是容器的5000端口
236cde0f69f9d17a7a23e7762e369174eb50dd82fb65c21aec9526b930b11b5f

4. 打标记，上传镜像

[root@test ~]# docker tag my_centos:latest 172.24.40.174:5000/my_centos:latest  //打标记
[root@test ~]# docker tag nginx:latest 172.24.40.174:5000/nginx:latest    //打标记
[root@test ~]# docker images   //查看镜像

[root@test ~]# docker push 172.24.40.174:5000/my_centos    //上传镜像
The push refers to a repository [172.24.40.174:5000/my_centos]
c41ed9d79ef4: Pushed 
9e607bb861a7: Pushed 
latest: digest: sha256:d5bbeb3f91e6abfdda2e9de886e33807961055fb6024ee7a48c1503560c146f3 size: 741

5. 客户端使用私有镜像源

也是需要配置daemon.json,内容和服务端一样
然后重启docker服务
docker run -it 172.24.40.174:5000/my_centos

小技巧
172.24.40.174:5000/v2/_catalog
//再浏览器上输入这个就可以查看私有仓库有哪些镜像
172.24.40.174:5000/v2/查出来的镜像名/tags/list
//可以查看该镜像下有哪些标签
