python - 尝试在 DockerFile 中 pip 安装私有(private)存储库

Question

我正在尝试安装自定义 Python 包以在 Flask 服务器中运行。服务器将位于 Docker 镜像中。因此，我试图对 RUN pip install git+ssh://git@bitbucket.org:teamName/reponame.git@dev#egg=packageName 进行操作但是，我尝试过的方法都不起作用。

我尝试了找到的两种格式:

1) git+ssh://git@bitbucket.org:teamName/reponame.git@dev#egg=packageName

2) git+ssh://bitbucket.org/team/reponame.git@dev#egg=packageName

这两种技术都会给出类似的错误:

fatal: Could not read from remote repository.

  Please make sure you have the correct access rights
  and the repository exists.

或

ssh: Could not resolve hostname bitbucket.org:TeamName: Name does not resolve
  fatal: Could not read from remote repository. 

或

root@bitbucket.org: Permission denied (publickey).
  fatal: Could not read from remote repository.

即使我的公钥设置在 BitBucket 中

这是 Dockerfile:

 Use an official Python runtime as a parent image
FROM python:3.6-alpine

#Preparation to pull from Github
ARG SSH_PRIVATE_KEY

RUN echo "Oh dang look at that ${SSH_PRIVATE_KEY}"

RUN apk update
RUN apk add --no-cache openssh \
    git

RUN mkdir /root/.ssh/
RUN echo "${SSH_PRIVATE_KEY}" > /root/.ssh/id_rsa

RUN chmod 600 /root/.ssh/id_rsa


RUN touch /root/.ssh/known_hosts
RUN ssh-keyscan bitbucket.org >> /root/.ssh/known_hosts

#install dependencies
RUN apk add --no-cache gcc \
    bash \
    tzdata \
    g++ \
    tiff-dev \
    openssl \
    poppler \
    poppler-dev \
    poppler-utils \
    && pip install --trusted-host pypi.python.org <THE_URL>
    && cp /usr/share/zoneinfo/America/that_place /etc/localtime \
    && echo "America/that_place" >  /etc/timezone \
    && date

# Set the working directory to /app
WORKDIR ./my_dir

# Make port 5000 available to the world outside this container
EXPOSE 5000

#Remove SSH
RUN rm /root/.ssh/id_rsa

# Define environment variable
ENV NAME __main__
ENV FLASK_APP app/app.py
ENV FLASK_RUN_HOST 0.0.0.0
ENV GOOGLE_APPLICATION_CREDENTIALS ./resources/google/credentials.json
ENV GOOGLE_CLOUD_BUCKET_NAME bucket_name

# Run app.py when the container launches
CMD ["flask", "run"]

SSH key 作为参数传递给构建 $(cat ./ssh/id_rsa)

Answer 1

您不想以这种方式传递 SSH key :它最终会出现在生成的镜像中，因此有权访问该镜像的任何人都可以访问您的 SSH key 。

选项:

1. 使用 BuildKit，它具有内置 SSH 代理转发 ( https://docs.docker.com/develop/develop-images/build_enhancements/#using-ssh-to-access-private-data-in-builds )。
2. 我在这里描述的技术太复杂，无法在简短的答案范围内涵盖:https://pythonspeed.com/articles/docker-build-secrets/
3. 如果您不担心泄露您的 SSH 私钥，请修复此设置。我的猜测是您还需要 chmod 700/root/.ssh。
