数据源： [root@host-10-0-101-156 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 056ee68c3788 rayosx:2.0.1 "/bin/bash" 29 hours ago Up 28 hours 0.0.0.0:5901->5900/tcp stupefied_murdock f21025fccdd9 rayosx:2.0.1 "/bin/bash" 2 weeks ago Up 44 hours 0.0.0.0:5906->5900/tcp romantic_bell ff2dacef1188 rayosx:2.0.1 "/bin/bash" 2 weeks ago Up 44 hours 0.0.0.0:5907->5900/tcp vibrant_hawking f0831061479f rayosx:2.0.1 "/bin/bash" 2 weeks ago Up 44 hours 0.0.0.0:5908->5900/tcp
用法：
1、查找端口
[root@host-10-0-101-156 ~]# docker inspect -f='{{range $conf := .NetworkSettings.Ports}}{{(index $conf 0).HostPort}} {{end}}' 056ee68c3788
5901
2、查找端口映射
[root@host-10-0-101-156 ~]# docker inspect -f='{{range $p, $conf := .NetworkSettings.Ports}}{{$p}} -> {{(index $conf 0).HostPort}} {{end}}' 056ee68c3788
5900/tcp -> 5901
3、启带端口映射的docker
[root@docker docker]# docker run -it -p 5907:5900 -v /opt:/gxycloud -v /sys/fs/cgroup:/sys/fs/cgroup --privileged --shm-size=1g fedora:25 /bin/bash
4、停止docker
[root@docker test]# docker stop 5219ceb7e061
5219ceb7e061
5、删除docker前要先停止
[root@docker test]# docker rm 5219ceb7e061
5219ceb7e061
6、docker帮助
[root@docker test]# docker --help
