描述：gitlab CI时，docker-compose部署服务时，报错端口被占用，且端口不能改变

方法：

1.使用docker-compose down server

netstat-anput | grep 5002

在启动看看是否可用

2.删除镜像/网络/容器/挂在目录

 docker network rm serverID

 docker container rm  serverID

 docker volume rm   serverID

 docker image rm serverID

重启server

3.重启docker

systemctlrestart docker

4.没测试（慎用，有可能将所有服务的network删除）

sudo cp/var/lib/docker/network/files/local-kv.db /var/lib/docker/network/files/local-kv.db_bk

sudo rm/var/lib/docker/network/files/local-kv.db

sudodocker-compose up -d
