docker私有倉庫搭建過程報錯

docker私有倉庫搭建報錯：

• http與https

  [[email protected] harbor]# docker ps -a
  CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                     NAMES

  [[email protected] harbor]# docker push 172.17.0.2:5000/game2048
  The push refers to repository [172.17.0.2:5000/game2048]
  Get https://172.17.0.2:5000/v2/: http: server gave HTTP response to HTTPS client           # 報錯
             

  原因：Docker從1.3.X之後，與docker registry互動預設使用的是https，然而此處搭建的私有倉庫隻提供http服務，是以當與

  私有倉庫互動時就會報上面的錯誤。為了解決這個問題需要在啟動docker server時增加啟動參數為預設使用http通路。

  修改docker啟動配置檔案：

  [[email protected] harbor]# vim /usr/lib/systemd/system/docker.service	  
   12 ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --insecure-registry 172.17.0.2:5000
             

  重讀重新開機docker：

  [[email protected] harbor]# systemctl daemon-reload 
  [[email protected] harbor]# systemctl restart docker
             

  重新上傳該鏡像：

  [[email protected] harbor]# docker push 172.17.0.2:5000/game2048
  The push refers to repository [172.17.0.2:5000/game2048]

  /mnt/registry私有庫目錄中會存在game2048鏡像：

  [[email protected] ~]# cd /mnt/registry/docker/registry/v2/repositories/
  [[email protected] repositories]# ls
  game2048
