Question

如何在docker容器中运行一个程序

Answer 1

交互式运行docker容器
[root@gage ~]#docker run -t -i ubuntu:14.04 /bin/bash
root@89471dce598b:/# ls
bin dev home lib64 mnt proc run srv tmp var
boot etc lib media opt root sbin sys usr
root@89471dce598b:/# pwd
/
root@89471dce598b:/# exit
exit
后台运行一个容器让其输出hello world
[root@gage ~]# docker run -d ubuntu:14.04 /bin/sh -c "while true; do echo hello world; sleep 1; done"

显示正在运行的docker容器
[root@gage ~]# docker ps
Container ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4bc1b2f2257e ubuntu:14.04 "/bin/sh -c 'while tr" 27 seconds ago Up 26 seconds insane_bhabha
使用docker logs命令查看容器标准输出
[root@gage ~]# docker logs insane_bhabha
hello world
hello world
hello world
hello world
使用docker stop 停止容器
[root@gage ~]# docker stop insane_bhabha
insane_bhabha
[root@gage ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
