ssh登录docker容器1、启动一个docker容器
# docker run -t -i ubuntu/ruby:v1 /bin/bash
2、然后在容器里，安装openssh-server openssh-client
# apt-get install openssh-server openssh-client
3、完成之后，修改root密码
# passwd
4、退出容器，并保存以上修改
# docker commit 3ea7a99a0025 ubuntu/ruby:v2
5、停止，并删除刚才的容器
# docker stop [container-id]
# docker rm [container-id]
查看容器id
# docker ps -a
查看镜像列表
# docker images
6、用刚保存的镜像，后台启动一个新的容器
docker run --name [image-name] -i -t -p 50001:22 [image-id]
例： # docker run -d -p 50001:22 ubuntu/ruby:v2 /usr/sbin/sshd -D
7、ssh远程登录该容器
# ssh [email protected] -p 50001
如果想要通过ssh密钥登录，则在第2步，修改 /etc/ssh/sshd_config 文件，将RSAAuthentication 和 PubkeyAuthentication 后面的值都改成yes ，保存。
将本地.ssh下的id_rsa.pub上传到容器中的 id_rsa.pub，并 # mv /root/.ssh/id_rsa.pub/root/.ssh/authorized_keys，然后 # chmod 600 /root/.ssh/authorized_keys 即可.
