    数据源:
    [root@host-10-0-101-156 ~]# docker ps -a
    CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                  PORTS                    NAMES

    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
