在docker容器中开启ssh服务 (未成功有时间再验证)

一、

利用ubuntu:14.04镜像创建一个容器：

[root@docker ~]# docker run -it ubuntu:14.04 /bin/bash
root@161f67ccad50:/# 

更新apt缓存：

root@161f67ccad50:/# apt-get update

2.安装和配置SSH服务

　　选择主流的openssh-server作为服务端：

root@161f67ccad50:/# apt-get install openssh-server net-tools passwd -y

openssh-server is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.
root@161f67ccad50:/# 

#启动服务

root@1b7d84e1e8ea:/# /usr/sbin/sshd -D &
[1] 9489
root@1b7d84e1e8ea:/# netstat -lntup|grep 22
