docker修改已经运行的容器的端口
一定要主机操作顺序，我操作了很久没成功 主要就是因为操作顺序问题1.停止容器
$ docker stop containerId
2.停止docker服务
$ service docker stop
3.修改文件
#/var/lib/docker/containers/[name]/hostconfig.json
#修改里面的端口设置（也需要修改config.v2.json文件）
hostconfig.json（主要要修改PortBindings HostIp为宿主机ip即可）

4.启动docker服务 启动容器
$ service docker stop
$ docker stop containerId
