Question

当Build试图克隆私人仓库时，我遇到了这个错误：

克隆到“。” ...主机密钥验证失败。致命：无法从远程存储库读取。请确保您具有正确的访问权限，并且存储库存在。

这是构建命令：

docker build --tag myimage --build-arg ssh_prv_key =“ $（cat 〜/ .ssh / id_rsa）“ --build-arg ssh_pub_key =” $（cat〜/ .ssh / id_rsa.pub）“

这是Dockerfile：

FROM tarampampam/node:13-alpine

ARG ssh_prv_key
ARG ssh_pub_key

RUN mkdir /root/.ssh/

RUN adduser "container" -D -h "/home/container"

RUN echo "$ssh_prv_key" > /root/.ssh/id_rsa && \
    echo "$ssh_pub_key" > /root/.ssh/id_rsa.pub && \
    chmod 600 /root/.ssh/id_rsa && \
    chmod 600 /root/.ssh/id_rsa.pub

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

RUN touch /root/.ssh/known_hosts
RUN echo -e "Host github.com\n\tStrictHostKeyChecking no\n" >> ~/.ssh/config
RUN ssh-keyscan -H github.com >> ~/.ssh/known_hosts

USER container
ENV  USER container
ENV  HOME /home/container

RUN cd /home/container && git clone git@github.com:myPrivateRepo .

RUN curl -sL https://deb.nodesource.com/setup_14.x | bash -    && apt update     && apt -y upgrade     && apt -y install nodejs node-gyp     && apt -y install ffmpeg     && npm install discord.js node-opus opusscript     && npm install >


WORKDIR /home/container

我已经检查过，/root/.ssh/id_rsa和/root/.ssh/id_rsa.pub都具有良好的密钥。

我尝试了很多选项，例如ssh-keygen -R github.com

问题是您为root用户设置了ssh环境，然后切换到用户容器（其中不存在ssh配置），然后尝试访问github。在〜container / .ssh中生成ssh配置。

Dockerfile-“主机密钥验证失败...”错误
