[系统运维]Docker服务启动报错:Job for docker.service failed because the control process exited with error

Docker服务启动报错:Job for docker.service failed because the control process exited with error

hrz@k8smaster:~$ sudo 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.

报错原因

我修改了/etc/docker/daemon.json文件，因为要配置docker驱动和k8s的相同，但是之前已经在该json文件写了docker镜像源，
再次添加的

{
  "exec-opts": ["native.cgroupdriver=systemd"]
}

原来json文件格式错了，两条数据之间要加逗号，然后继续重启docker解决

解决方法

解决方法就是检查这个json文件是否格式写错了

重启

# 重启docker
sudo systemctl daemon-reload
sudo systemctl restart docker
