切记：以下顺序千万不能颠倒！否则不生效！

1. 查看需要修改的容器，记住container id
docker ps -a
2. 停止容器
docker stop xxx
3. 修改容器的端口映射配置文件
vim /var/lib/docker/containers/{container_id}/hostconfig.json

"PortBindings": {
      "80/tcp": [
              {
              "HostIp": "",
              "HostPort": "8080"//宿主机ip
              }
          ]
      },
4. 重启docker服务
service docker restart
5.启动容器
docker start xxx
