docker daemon.json肯多多_daemon.json daemon.conf

修改了harbor，想传个镜像到Registry，结果改了daemon就出错了

异常如下：

[root@localhost docker]# systemctl status docker.service
● docker.service - Docker Application Container Engine

后来再看看异常信息，是docker启动服务报错了

[root@localhost docker]# systemctl start docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

修改了daemon文件，然后出现这个问题

[root@localhost docker]# systemctl daemon-reload;service docker restart
Redirecting to /bin/systemctl restart docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

最后定位到原因，需要改后缀，把daemon.json，改daemon.conf

[root@localhost docker]# mv daemon.json daemon.conf
[root@localhost docker]# systemctl daemon-reload;service docker restart
Redirecting to /bin/systemctl restart docker.service
