错误的daemon.json配置,导致docker容器启动失败 Failed to start Docker Application Container Engine
docker学习-配置错误的源
问题点剖析
使用docker安装了nginx
,编写Dockerfile
,映射端口,终于跑起来了。但是,当我重启服务器,再次查看docker
容器的状态,发现报错了。
# docker ps -a
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
然后重启docker
# sudo service docker start
Redirecting to /bin/systemctl start docker.service
Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.
发现还是不行,根据提示查看docker.service
的status
# systemctl status docker.service
● docker.service - Docker Application Container Engine

分析发现原因是docker不能启动
Failed to start Docker Application Container Engine.
daemon.json
如果包含格式不正确的JSON
,Docker
将无法启动
检查了一下daemon.json
,果真,少了一个“
。
修改daemon.json
,然后重启解决了。
