1,首先,需要从Docker官网获得centos或Ubuntu镜像
2,当本地已有Ubuntu镜像后(大概200M左右大小),使用如下命令
- docker run -t -i ubuntu /bin/bash
3,更新源, apt-get update
接着就可以使用 apt-get install openssh-client openssh-server 来安装openssh服务了
需要把此镜像保存一下:
- docker commit [container-id] [image-id]
- docker stop [container-id]
- docker rm [container-id]
最后,加载刚刚保存到的最新的image,放入到新的容器中去:
- docker run --name [image-name] -i -t -p 50001:22 [image-id]
4,启动openssh服务
- /etc/init.d/ssh start
5,此时可以从其他机器登陆到这个docker容器里了
6,可能出现一些错误使得一登陆进去就直接关闭连接了:
- [root@Wshare84 start_docker_sh]# ssh root@10.10.2.84 -p 50001
- The authenticity of host '[10.10.2.84]:50001 ([10.10.2.84]:50001)' can't be established.
- RSA key fingerprint is aa:05:84:4c:f2:15:f3:04:89:9c:04:33:0d:15:14:1f.
- Are you sure you want to continue connecting (yes/no)? yes
- Warning: Permanently added '[10.10.2.84]:50001' (RSA) to the list of known hosts.
- root@10.10.2.84's password:
- Welcome to Ubuntu 14.04.1 LTS (GNU/Linux 2.6.32-431.el6.x86_64 x86_64)
- * Documentation: https://help.ubuntu.com/
- Last login: Wed Jan 21 01:25:17 2015 from 172.17.42.1
- Connection to 10.10.2.84 closed.
此时解决方案:
- ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
- ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
- echo 'root:yourpasswd' | chpasswd //设置root密码
- vi /etc/ssh/sshd_config
重启服务:
- /etc/init.d/ssh restart
