  • 实验:构建本地无认证docker仓库registry

    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
    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
    Trying to pull repository 192.168.102.131:5000/mybusybox ...
    latest: Pulling from 192.168.102.131:5000/mybusybox
    Digest: sha256:186694df7e479d2b8bf075d9e1b1d7a884c6de60470006d572350573bfa6dcd2
    Status: Downloaded newer image for 192.168.102.131:5000/mybusybox:latest
