当我们向私有仓库推送镜像,如下:
$ docker push 10.255.67.131:5000/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自从1.3.X之后docker registry交互默认使用的是HTTPS,但是搭建私有镜像默认使用的是HTTP服务导致。
处理办法如下:
# 修改启动文件第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"] }
重启docker服务
$ systemctl daemon-reload $ systemctl restart docker
如出现如下报错:
$ 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.
这个可能是/etc/docker/daemon.json内容配置有误,需要认真检查;
或者/etc/sysconfig/docker里面已经配置了insecure-registries内容,重复配置导致的问题,删掉重复的insecure-registries内容即可。
结束!
