git - 从 Dockerfile 克隆私有(private) git 存储库

标签 git docker ssh ssh-keys

我的目标是从 Dockerfile 克隆私有(private)存储库。我复制我的私有(private) SSH key ,然后将 bitbucket.org 域添加到 known_hosts 文件中,但是当我尝试克隆存储库时,由于某种原因,我收到“权限被拒绝”错误。不过,我可以从我的主机克隆这个存储库。我错过了什么?

Dockerfile:

FROM ubuntu

RUN apt-get update
RUN apt-get install -y git ssh

ARG SSH_PRIVATE_KEY
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

RUN git clone <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6f08061b2f0d061b0d1a0c040a1b41001d08" rel="noreferrer noopener nofollow">[email protected]</a>:foo/bar.git

命令:

docker build --build-arg SSH_PRIVATE_KEY="$(cat ~/.ssh/id_rsa)" .

输出:

Warning: Permanently added the RSA host key for IP address '18.205.93.2' to the list of known hosts.

and the repository exists.

最佳答案

您需要确保 id_rsa 填写正确:

docker build --build-arg SSH_PRIVATE_KEY="$(cat ~/.ssh/id_rsa)" .

编辑 这仅适用于没有密码的 key ,否则事情会变得复杂。
