【docker】搭建本地私有镜像库（转）

转自：https://www.cnblogs.com/mathprice/p/9024606.html

实验：本地仓库

1、拉取registry

docker pull registry

2、修改json文件，增加本地无认证仓库地址

vi /etc/docker/daemon.json

{

"insecure-registries":["本地ip:5000"]

}

3、重启docker服务

[root@localhost ~]# systemctl daemon-reload

[root@localhost ~]# systemctl restart docker

4、开启registry容器

docker run -idt -v /root/opt:/var/lib/registry -p 5000:5000 --restart=always --name=myregistry --privileged=true registry

开启终端和输入并且后台运行

映射本地/root/opt到容器内的/var/lib/registry

映射本机5000端口到容器5000端口

重启容器，总是

名称myregistry。开启特权模式

镜像为 registry

5、验证端口开启，验证仓库

ss -nlt 查看5000端口是否打开

主机访问网址 http://ip:5000/v2/_catalog

显示{"repositories":[]} 说明开启了

6、给镜像打私有tag

先下载一个busybox

docker pull busybox

打tag

docker tag busybox 192.168.102.131:5000/mybusybox

docker images

192.168.102.131:5000/mybusybox latest 8ac48589692a 4 weeks ago 1.15 MB

docker.io/busybox latest 8ac48589692a 4 weeks ago 1.15 MB

7、推送到本地私有仓库

docker push 192.168.102.131:5000/mybusybox

8、验证

主机访问网址 http://192.168.102.131:5000/v2/_catalog

显示{"repositories":["mybusybox"]}

说明mybusybox已经上传到仓库

[root@localhost ~]# docker exec -it registy sh

/ # ls /var/lib/registry/docker/registry/v2/repositories

mybusybox

/ # ls /var/lib/registry/docker/registry/v2/repositories/mybusybox/

_layers _manifests _uploads

 

9、从私有仓库下载

为了看到效果，先删掉原来的镜像

docker rmi 192.168.102.131:5000/mybusybox

docker images

[root@localhost ~]# docker pull 192.168.102.131:5000/mybusybox

Using default tag: latest
