Docker镜像 配置ssh

安装

1.安装ssh
2.设置root密码

RUN echo 'root:123456' | chpasswd 

3.设置sshd config

RUN echo 'Port 22' >> /etc/ssh/sshd_config 
RUN echo 'PermitRootLogin yes' >>  /etc/ssh/sshd_config

4.设置开机启动

RUN mkdir /var/run/sshd #没有这个目录，ssh会挂掉
CMD ["/usr/sbin/sshd","-D"]

或者

RUN echo 'service ssh start' >>  /root/.bashrc

Dockerfile

• docker容器SSH服务自启动
• Dockerfile部署带有ssh的Ubuntu
