Bind for 0.0.0.0:8181 failed: port is already allocated

Docker 错误 “port is already allocated” 解决方法
Docker 在启动容器时，报出了下面的错误：

docker: Error response from daemon: driver failed programming external connectivity on endpoint … (…): Bind for 0.0.0.0:8080 failed: port is already allocated.

查看进程，发现相关的容器并没有在运行，而 docker-proxy 却依然绑定着端口：

$ docker ps
$ ps -aux | grep -v grep | grep docker-proxy

ps -aux | grep -v grep | grep gitlab-gitlab-1

停止 doker 进程，删除所有容器，然后删除 local-kv.db 这个文件，再启动 docker 就可以了。

$ sudo service docker stop
$ docker rm $(docker ps -aq)
$ sudo rm /var/lib/docker/network/files/local-kv.db
$ sudo systemctl restart docker
