我有一个应用程序，执行各种有趣的东西与Git(像运行Git克隆& Git推送)，我试图docker-ize它。
我遇到了一个问题，虽然我需要能够添加一个SSH密钥到容器的容器“用户”使用。
我试着把它复制到/root/。ssh/，更改$HOME，创建一个git ssh包装器，仍然没有运气。
以下是Dockerfile供参考:
#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git命令，比如git pull
在我的情况下，我有一个问题与nodejs和'npm I '从一个远程存储库。我修复了添加'node'用户到nodejs容器和700到~/。容器中的SSH。
Dockerfile：
USER node #added the part
COPY run.sh /usr/local/bin/
CMD ["run.sh"]
run.sh:
#!/bin/bash
chmod 700 -R ~/.ssh/; #added the part
docker-compose.yml:
nodejs:
build: ./nodejs/10/
container_name: nodejs
restart: always
ports:
- "3000:3000"
volumes:
- ../www/:/var/www/html/:delegated
- ./ssh:/home/node/.ssh #added the part
links:
- mailhog
networks:
- work-network
在那之后，它开始工作
从docker API 1.39+(检查API版本和docker版本)开始，docker构建允许——ssh选项与代理套接字或键一起允许docker引擎转发ssh代理连接。
建造的命令
export DOCKER_BUILDKIT=1
docker build --ssh default=~/.ssh/id_rsa .
Dockerfile
# syntax=docker/dockerfile:experimental
FROM python:3.7
# Install ssh client (if required)
RUN apt-get update -qq
RUN apt-get install openssh-client -y
# Download public key for github.com
RUN --mount=type=ssh mkdir -p -m 0600 ~/.ssh && ssh-keyscan github.com >> ~/.ssh/known_hosts
# Clone private repository
RUN --mount=type=ssh git clone git@github.com:myorg/myproject.git myproject

一个简单而安全的方法来实现这一点，而不需要将密钥保存在Docker镜像层中，或通过ssh_agent体操:
As one of the steps in your Dockerfile, create a .ssh directory by adding:
RUN mkdir -p /root/.ssh
Below that indicate that you would like to mount the ssh directory as a volume:
VOLUME [ "/root/.ssh" ]
Ensure that your container's ssh_config knows where to find the public keys by adding this line:
RUN echo " IdentityFile /root/.ssh/id_rsa" >> /etc/ssh/ssh_config
Expose you local user's .ssh directory to the container at runtime:
docker run -v ~/.ssh:/root/.ssh -it image_name
Or in your dockerCompose.yml add this under the service's volume key:
- "~/.ssh:/root/.ssh"
你最终的Dockerfile应该包含如下内容:
FROM node:6.9.1
RUN mkdir -p /root/.ssh
RUN echo " IdentityFile /root/.ssh/id_rsa" >> /etc/ssh/ssh_config
VOLUME [ "/root/.ssh" ]
EXPOSE 3000
CMD [ "launch" ]
这一行是个问题:
ADD ../../home/ubuntu/.ssh/id_rsa /root/.ssh/id_rsa
当指定要复制到映像中的文件时，只能使用相对路径——相对于Dockerfile所在的目录。所以你应该用:
ADD id_rsa /root/.ssh/id_rsa
将id_rsa文件放到Dockerfile所在的目录中。
