Docker--建立私有仓库
- 部署私有仓库
-
- 1.拉私仓镜像
- 2.修改daemon.json配置
- 3.创建registry
- 4.启动
- 5.标记镜像
- 6.将镜像推到私仓
- 7.删除并重新下载
Docker 官方提供了一个名字 registry 当地私人仓库使用的镜像。构建内部网络 Docker 私人仓库可以快速下载和上传内网人员，不受外网带宽等因素的影响。同时，不在内网的人无法下载我们的镜像，私人仓库还支持仓库认证功能的配置。接下来详细说明 registry 建设私有仓库的过程。
部署私人仓库
1.拉私仓镜像
[root@localhost ~]# docker pull registry 2.修改daemon.json配置
[root@localhost ~]# vim /etc/docker/daemon.json 添加以下内容，让 Docker 信任私人仓库地址，保存退出。
{
"insecure-registries": ["192.168.220.101:5000"], "registry-mirrors": ["https://8eueg49g.mirror.aliyuncs.com"] } 重启
[root@localhost ~]# systemctl daemon-reload [root@localhost ~]# systemctl restart docker 3.创建registry
[root@localhost ~]# docker create -it registry /bin/bash ecdc9d451b85792d2fe9a8cb5f84cb4929669030597855c02c2a2eb04adbba76 [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ecdc9d451b85 registry "/entrypoint.sh /bin…" 8 seconds ago Created lucid_einstein 4.启动
[root@localhost ~]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry e42a3392761f16feca61cdc53c757174997881466532179d7cf12aa142fc4aff [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e42a3392761f registry "/entrypoint.sh /etc…" 18 seconds ago Up 17 seconds 0.0.0.0:5000->5000/tcp, :::5000->5000/tcp priceless_banach
5.给镜像上标签
[root@localhost ~]# docker tag nginx:new 192.168.220.101:5000/nginx
6.将镜像推送至私有仓库
[root@localhost ~]# docker push 192.168.220.101:5000/nginx
Using default tag: latest
The push refers to repository [192.168.220.101:5000/nginx]

7.删除并重新下载
[root@localhost ~]# docker rmi 192.168.220.101:5000/nginx:latest
