配置Docker容器ssh服务端实现远程ssh登录

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
