Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

當我們向私有倉庫推送鏡像，如下：

$ docker push *.*.*.*:5000/pod-infrastructure:latest
The push refers to a repository [*.*.*.*:5000/pod-infrastructure]
Get https://*.*.*.*:5000/v1/_ping: http: server gave HTTP response to HTTPS client

原因是：Docker自從1.3.X之后docker registry交互默認使用的是HTTPS，但是搭建私有鏡像默認使用的是HTTP服務導致。

處理辦法如下：

# 修改啟動文件第12行 
$ vim /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd --insecure-registry *.*.*.*:5000

或者

$ vim /etc/docker/daemon.json
{
"insecure-registries":["*.*.*.*:5000"]
}

重啟docker服務

$ systemctl daemon-reload
$ systemctl restart docker

如出現如下報錯：

$ systemctl restart docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

 這個可能是/etc/docker/daemon.json內容配置有誤，需要認真檢查；

或者/etc/sysconfig/docker里面已經配置了insecure-registries內容，重復配置導致的問題，刪掉重復的insecure-registries內容即可。

結束！
