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

问题描述

我有一个使用 Git 执行各种有趣内容的应用程序(例如运行 git clone 和 git push)，我正在尝试对其进行 docker-ize.

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.

我遇到了一个问题，我需要能够将 SSH 密钥添加到容器以供容器用户"使用.

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.

我尝试将它复制到 /root/.ssh/，更改 $HOME，创建一个 git ssh 包装器，但仍然没有运气.

I tried copying it into /root/.ssh/, changing $HOME, creating a git ssh wrapper, and still no luck.

这里是 Dockerfile 供参考:

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 运行像 git pull

推荐答案

原来在使用 Ubuntu 时，ssh_config 不正确.您需要添加

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

到您的 Dockerfile 以使其识别您的 ssh 密钥.

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