我在我的ubuntu机器上安装了docker image - centos 7。但是找不到ssh服务。所以我不能运行这项服务。

您必须在Dockerfile上执行以下指示。

RUN yum install -y sudo wget telnet openssh-server vim git ncurses-term
RUN useradd your_account

RUN mkdir -p /home/your_account/.ssh && chown -R your_account   /home/your_account/.ssh/ 

# Create known_hosts
RUN touch /home/your_account/.ssh/known_hosts


COPY files/authorized_keys /home/your_account/.ssh/
COPY files/config          /home/your_account/.ssh/
COPY files/pam.d/sshd      /etc/pam.d/sshd
RUN touch /home/your_account/.ssh/environment
RUN chown -R your_account /home/your_account/.ssh
RUN chmod 400 -R  /home/your_account/.ssh/*
RUN chmod 700 -R  /home/your_account/.ssh/known_hosts
RUN chmod 700  /home/your_account/.ssh/environment


# Enable sshd
COPY files/sshd_config /etc/ssh/
RUN ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa 

# Add a account into sudoers and this account doesn't need to type his password
COPY files/sudoers /etc/
COPY files/start.sh /root/

我必须删除" pam_nologin.so"在文件/etc/pam.d/sshd上,因为当我将openssh-server的版本升级到openssh-server-6.6.1p1-31.el7时,pam_nologin.so将禁止任何用户的远程登录文件/ etc / nologin不存在。

start.sh

#!/bin/bash
/usr/sbin/sshd -E /tmp/sshd.log

启动centos容器

  • docker run -d -t -p $(sshPort):22 --name $(containerName)$(imageName)/ bin / bash
  • docker exec -d $(containerName)bash -c" sh /root/start.sh"

登录容器

  • ssh $(Docker ip)$(sshPort)

扩展到@puritys

您可以在Dockerfile中执行此操作

文件中的最后一行:

 ENTRYPOINT /usr/sbin/sshd -E /tmp/sshd.log && /bin/bash

然后你只需要运行:

 docker run -d -p -t $(sshPort):22 --name $(containerName) $(imageName) /bin/bash
