1. ubuntu系统

#安装ssh server 和 client
    
    RUN  DEBIAN_FRONTEND=noninteractive  apt-get install -y  openssh-server openssh-client
    
    #此步骤主要目的是修改sshd_config配置文件，把配置文件中的”PermitRootLogin without-password”加一个”#”号,把它注释掉，再增加一句”PermitRootLogin yes”，参考：https://www.jianshu.com/p/adda91b7c1d2
    
    RUN mv /etc/ssh/sshd_config /etc/ssh/sshd_config_bak && cp /opt/sshd_config /etc/ssh/
    
    ## 设置root密码为123
    RUN echo root:123 | chpasswd
    
    
    RUN echo "export PATH=/usr/local/nvidia/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" >> /root/.bashrc
    RUN echo "export LD_LIBRARY_PATH=/usr/local/nvidia/lib:/usr/local/nvidia/lib64" >> /root/.bashrc
    ## ssh port 22
    EXPOSE 22
    
    
    ## ssh start cmd
    CMD service ssh restart -D

2、centos系统

FROM nvidia/cuda:9.0-cudnn7-devel-centos7
    LABEL maintainer "xxx"
    
    RUN mv /etc/yum.repos.d/cuda.repo /etc/yum.repos.d/cuda.repo.bak && \
        yum install -y vim openssh-server openssh-clients && \
        rm -rf /var/cache/yum/*
    
    COPY sshd_config /etc/ssh
    #COPY ssh_host_rsa_key /etc/ssh
    RUN echo \n\n | ssh-keygen -t rsa -b 2048 -f /etc/ssh/ssh_host_rsa_key
    ## 设置root密码
    RUN echo root:123 | chpasswd
    
    RUN echo "export PATH=/usr/local/nvidia/bin:/usr/local/cuda/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" >> /root/.bashrc
    RUN echo "export LD_LIBRARY_PATH=/usr/local/nvidia/lib:/usr/local/nvidia/lib64" >> /root/.bashrc
    ## ssh port 22
    EXPOSE 22
    
    ## ssh start cmd
    CMD /usr/sbin/sshd -D

3、镜像制作好后在机器上启动容器

以GPU机器为例子，分配10核cpu，30G内存，启动命令如下：

NV_GPU=0 nvidia-docker run --name ajk-caffe-offline-GPU -itd --cpu-period 100000 --cpu-quota 1000000 --memory 30G --shm-size 2G  -p 50011:22 -p 50012:50012 -p 50013:50013 -p 50014:50014 -v /opt/users/xxx/:/home/work/ 镜像名

4、其他机器远程 ssh 登录

ssh -p 50011 root@xxx.xxx.x.xxx
