Docker建立私有仓库

Posted 2020-12-29

Docker（五）建立私有仓库

随着创建的镜像日益增多，就需要一个保存镜像的地方，这就是仓库。

仓库目前有两张：

1：公有仓库

2：私有仓库

私有仓库建立

[[email protected] ~] docker pull registry
Using default tag: latest
latest: Pulling from library/registry
4064ffdc82fe: Pull complete 
c12c92d1c5a2: Pull complete 
4fbc9b6835cc: Pull complete 
765973b0f65f: Pull complete 
3968771a7c3a: Pull complete 
Digest: sha256:51bb55f23ef7e25ac9b8313b139a8dd45baa832943c8ad8f7da2ddad6355b3c8
Status: Downloaded newer image for registry:latest

之后需要在/etc/docker/目录底下创建json文件，否则就会报错

[[email protected] ~] vim /etc/docker/daemon.json
{"insecure-registries":["192.168.179.152:5000"]}

重启服务：上传时候回报错

[[email protected] ~]# systemctl restart docker.service

本地启动的私有仓库监听地址为5000

docker create -it registry /bin/bash
docker ps -a

//宿主机的/data/registry自动创建挂载容器中的/tmp/registry
docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry

//更改标记为192.168.179.152:5000/cobbler
docker tag jasonlix/docker-cobbler 192.168.175.145:5000/cobbler

//上传
docker push 192.168.179.152:5000/cobbler
