github - Docker:从私有(private) GitHub 存储库中获取

Question

我正在尝试运行一个容器，该容器将从我在私有(private) GitHub 存储库中的包中公开 golang 服务。

由于我正在使用 GCE，因此我的起始图像是 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>

其中包是私有(private)仓库。

我已经添加了我的 GitHub SSH key 以允许从私有(private) repo 克隆到 docker 文件:

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

不过，当 go 尝试克隆 repo 时，我在 go get 过程中遇到错误:

# 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

为了调试问题，我正在运行 Dockerfile:

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

这告诉我存在一些问题。看起来验证私钥是可以的，但是公钥上发生了一些奇怪的事情。这是完整的 ssh-keyscan 结果:

我在 priv/public key 上尝试了 chmod 600 和 chmod 700，但这没有帮助。

有什么线索吗？有没有人成功运行 go get 从 docker 上的 debian 上的私有(private) repos 获取？

经过一番折腾，我明白了这一点。这不是一个理想的解决方案，因为它涉及安装 SSH，以及在容器中构建私钥。本例基于官方Docker golang image (Debian Wheezy):

与您的示例的主要区别在于您需要一个 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://git@github.com/.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
