在docker容器中開啟ssh服務 (未成功有時間再驗證)

一、

利用ubuntu:14.04鏡像創建一個容器：

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

更新apt緩存：

root@161f67ccad50:/# apt-get update

2.安裝和配置SSH服務

　　選擇主流的openssh-server作為服務端：

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:/# 

#啟動服務

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