Docker：从私有GitHub存储库中获取

Question

我正在尝试运行一个容器，该容器将公开私有GitHub存储库上的软件包中的golang服务。

由于我与GCE合作，因此我的入门图片是google / debian：wheezy。

安装所有必需的依赖项和工具后，我正在运行

RUN go get github.com/<my_org>/<my_package>

包裹是私人仓库。

我添加了GitHub SSH密钥以允许从私有存储库克隆到docker文件：

ADD priv/id_rsa /root/.ssh/id_rsa
ADD priv/id_rsa.pub /root/.ssh/id_rsa.pub

尽管如此，当go尝试克隆存储库时，我在go get流程中遇到了一个错误：

# cd .; git clone https://github.com/<my_org>/<my_package> /gopath/src/github.com/<my_org>/<my_package>
Cloning into '/gopath/src/github.com/<my_org>/<my_package>'...
fatal: could not read Username for 'https://github.com': No such device or address
package github.com/<my_org>/<my_package>: exit status 128

为了调试该问题，我正在从Dockerfile运行：

RUN ssh-keyscan -t rsa github.com 2>&1 >> /root/.ssh/known_hosts

这告诉我有一些问题。看起来好像验证私钥是可以的，但是在公钥上发生了奇怪的事情。这是完整的ssh-keyscan结果：

我在专用/公共密钥上尝试过chmod 600和chmod 700，这没有帮助。

有什么线索吗？有谁成功运行go从docker的debian上的私人仓库中获取go？

Answer 1

经过一番破解之后，我发现了这一点。这不是理想的解决方案，因为它涉及安装SSH，以及在容器中构建私钥。这个例子基于官方的Docker
golang镜像
（Debian Wheezy）：

您的示例的主要区别在于您需要git config命令来强制使用ssh而不是默认的https。

FROM golang

RUN apt-get update && apt-get install -y ca-certificates git-core ssh

ADD keys/my_key_rsa /root/.ssh/id_rsa
RUN chmod 700 /root/.ssh/id_rsa
RUN echo "Host github.com\n\tStrictHostKeyChecking no\n" >> /root/.ssh/config
RUN git config --global url.ssh://[e-mail]/.insteadOf https://github.com/

ADD . /go/src/github.com/myaccount/myprivaterepo

RUN go get github.com/myaccount/myprivaterepo
RUN go install github.com/myaccount/myprivaterepo
