Docker：从一个私人的GitHub仓库获取
我试图运行一个容器，将暴露一个包，我有一个私人的GitHub回购一个golang服务。
由于我正在使用GCE，我的初始图像是谷歌/ debian：wheezy。
安装所有必需的依赖和工具后，我正在运行
RUN go get github.com/<my_org>/<my_package> 该包是私人回购。
我已经添加了我的GitHub SSH密钥，以允许从私人回购克隆到泊坞窗文件：
ADD priv/id_rsa /root/.ssh/id_rsa ADD priv/id_rsa.pub /root/.ssh/id_rsa.pub
不过，在尝试克隆repo时，在获取过程中出现错误：
# 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debugging这个问题，从Dockerfile中运行：
RUN ssh-keyscan -t rsa github.com 2>&1 >> /root/.ssh/known_hosts
这告诉我有一些问题。 它看起来像validation私钥是好的，但奇怪的是在公钥上。 这是完整的ssh-keyscan结果：

我已经在priv / public keys上尝试了chmod 600和chmod 700，这没有帮助。
任何线索？ 有没有人成功运行去获取从docker的debian私人回购？
在经过一些黑客攻击之后，我想到了这一点。 这不是一个理想的解决scheme，因为它涉及安装SSH，并在容器中构build私钥。 这个例子是基于官方的Docker golang镜像 （Debian Wheezy）：
你的例子的主要区别是，你需要一个git config命令来强制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
go get是试图使用https，完全忽略SSH。
你将不得不设置~/.netrc ：
ADD priv/.netrc /root/.netrc
netrc看起来像：
machine github.com login github-username password github-password
参考：
在OneOfOne的~/.netrc答案详细说明，这就是我正在做的与Jenkins在Linux上：
FROM golang:1.6 ARG GITHUB_USER=$GITHUB_USER ARG GITHUB_PASS=$GITHUB_PASS # Copy local package files to the container's workspace. ADD . /go/src/github.com/my-org/my-project WORKDIR /go/src/github.com/my-org/my-project/ # Build application inside the container. RUN echo "machine github.com\n\tlogin $GITHUB_USER\n\tpassword $GITHUB_PASS" >> ~/.netrc && \ go get github.com/tools/godep && \ go get github.com/onsi/ginkgo/ginkgo && \ godep restore && \ ginkgo -r --randomizeAllSpecs --randomizeSuites --failOnPending && \ godep go install && \ rm -f ~/.netrc ENTRYPOINT /go/bin/my-project EXPOSE 8080
docker build命令是：
docker build \ --build-arg GITHUB_USER=xxxxx \ --build-arg GITHUB_PASS=yyyyy \ -t my-project .
两个ARG指令映射--build-arg s，因此docker可以在Dockerfile中使用它们。
RUN的第一行和最后一行创build并删除~/.netrc 。
在Jenkins中，我在构build命令中使用了git pull中相同的声明。
在此策略中，docker构build过程中密码不会被回显，也不会保存在泊坞窗图像的任何图层上。 另外请注意，在构build过程中将银杏testing结果打印到控制台。
