Docker私有仓库

私有仓库搭建

首先启动docker

• 拉取私有仓库镜像

  [root@server-a ~]# docker pull registry
  Using default tag: latest
  latest: Pulling from library/registry
  79e9f2f55bf5: Pull complete
  0d96da54f60b: Pull complete
  5b27040df4a2: Pull complete
  e2ead8259a04: Pull complete
  3790aef225b9: Pull complete
  Digest: sha256:169211e20e2f2d5d115674681eb79d21a217b296b43374b8e39f97fcf866b375
  Status: Downloaded newer image for registry:latest
  docker.io/library/registry:latest
  

• 启动私有仓库容器

  [root@server-a ~]# docker run -id --name=registry -p 5000:5000 registry
  

• 打开浏览器，输入地址http://私有仓库服务器 ip:5000/v2/_catalog

  

• 修改daemon json 追加信息

  [root@server-a ~]# vim /etc/docker/daemon.json
  [root@server-a ~]# cat /etc/docker/daemon.json
  {
   "registry-mirrors": ["https://m03eesz2.mirror.aliyuncs.com"],
  "insecure-registries":["192.168.10.128:5000"]
  }
  

• 重启服务

systemctl restart docker
docker start registry

将镜像上传至私有仓库

• 查看镜像

  [root@server-a ~]# docker images
  REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
  app          latest    d8cb1b6dcd58   30 hours ago    488MB
  nginx        latest    605c77e624dd   16 months ago   141MB
  openjdk      latest    5f94f53bbced   16 months ago   471MB
  tomcat       latest    fb5657adc892   16 months ago   680MB
  registry     latest    b8604a3fe854   18 months ago   26.2MB
  centos       7         eeb6ee3f44bd   20 months ago   204MB
  

• 将centos7传入仓库,先打上标记

  [root@server-a ~]# docker tag centos:7 192.168.10.128:5000/centos:7
  [root@server-a ~]# docker images
  REPOSITORY                   TAG       IMAGE ID       CREATED         SIZE
  app                          latest    d8cb1b6dcd58   30 hours ago    488MB
  nginx                        latest    605c77e624dd   16 months ago   141MB
  openjdk                      latest    5f94f53bbced   16 months ago   471MB
  tomcat                       latest    fb5657adc892   16 months ago   680MB
  registry                     latest    b8604a3fe854   18 months ago   26.2MB
  192.168.10.128:5000/centos   7         eeb6ee3f44bd   20 months ago   204MB
  centos                       7         eeb6ee3f44bd   20 months ago   204MB
  

• 错误

  [root@server-a ~]# docker push 192.168.10.128:5000/centos
  
  Using default tag: latest
  The push refers to repository [192.168.10.128:5000/centos]
  tag does not exist: 192.168.10.128:5000/centos:latest
  

  这段话提示没有此标签，检查了下，这里我的centos后面没有加上版本号7 ，如果你是latest就不用加

• 解决

 [root@server-a ~]# docker push 192.168.10.128:5000/centos:7
The push refers to repository [192.168.10.128:5000/centos]

• 访问http://私有仓库服务器 ip5000/v2/_catalog

从私有仓库拉取镜像

• 首先把之前的镜像删除

[root@server-a ~]# docker rmi 192.168.10.128:5000/centos:7
