在docker容器内使用SSH密钥 [英] Using SSH keys inside docker container

问题描述

好吧，基本上我有一个应用程序，用Git执行各种有趣的东西（如运行git clone& git push），我正在尝试对它进行docker。

我遇到一个问题，但我需要在容器中添加一个SSH密钥才能使用该容器。

有没有办法做到这一点？我尝试将它复制到/root/.ssh/中，更改$ HOME，创建一个git ssh包装器，但仍然没有运气。

以下是Docker文件供参考：

 ＃DOCKER-VERSION ubuntu中的0.3.4 
 
：$ 12 
 
运行apt-get update 
运行apt-get install python-software-properties python g ++ make git-core openssh- server -y 
 RUN add-apt-repository ppa：chris-lea / node.js 
 RUN echodeb http://archive.ubuntu.com/ubuntu precise universe>> /etc/apt/sources.list 
运行apt-get update 
运行apt-get install nodejs -y 
 
添加。 / src 
 ADD ../../home/ubuntu/.ssh/id_rsa /root/.ssh/id_rsa 
 RUN cd / src; npm安装
 
 EXPOSE 808：808 
 
 CMD [node，/src/app.js] 
  

app.js 运行git命令，如 git pull

解决方案

使用Ubuntu时，ssh_config不正确。您需要添加

 运行echoIdentityFile〜/ .ssh / id_rsa>> / etc / ssh / ssh_config 
  

到您的Docker文件，以使其识别您的ssh密钥。 / p>

Alright, so essentially I have an app that executes various fun stuff with Git (like running git clone & git push) and I'm trying to docker-ize it.

I'm running into an issue though where I need to be able to add an SSH key to the container for the container 'user' to use.

Is there a good way to do this? I tried copying it into /root/.ssh/, changing $HOME, creating a git ssh wrapper, and still no luck.

Here is the Dockerfile for reference:

#DOCKER-VERSION 0.3.4                                                           

from  ubuntu:12.04                                                              

RUN  apt-get update                                                             
RUN  apt-get install python-software-properties python g++ make git-core openssh-server -y
RUN  add-apt-repository ppa:chris-lea/node.js                                   
RUN  echo "deb http://archive.ubuntu.com/ubuntu precise universe" >> /etc/apt/sources.list
RUN  apt-get update                                                             
RUN  apt-get install nodejs -y                                                  

ADD . /src                                                                       
ADD ../../home/ubuntu/.ssh/id_rsa /root/.ssh/id_rsa                             
RUN   cd /src; npm install                                                      

EXPOSE  808:808                                                                 

CMD   [ "node", "/src/app.js"]

app.js runs the git commands like git pull

解决方案

Turns out when using Ubuntu, the ssh_config isn't correct. You need to add

RUN  echo "    IdentityFile ~/.ssh/id_rsa" >> /etc/ssh/ssh_config

to your Dockerfile in order to get it to recognize your ssh key.
