Question

我试图运行一个容器，该容器将从我在私有GitHub存储库上的包中公开golang服务。

由于我正在与GCE合作，我的初学者形象是google / debian：wheezy。

安装完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。

我添加了我的GitHub SSH密钥，允许从私有仓库克隆到docker文件：

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

但是，当我试图克隆回购时，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

要调试问题，我从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。看起来验证私钥是否正常，但公钥上有些奇怪。这是完整的ssh-keyscan结果：

我在priv / public键上尝试了chmod 600和chmod 700，这没有用。

任何线索？有没有人成功运行从docker的debian私人回购获取？

go get正在尝试使用https，完全忽略ssh。

您必须设置~/.netrc：

ADD priv/.netrc /root/.netrc

netrc的样子：

machine github.com login github-username password github-password

我在经过一番黑客攻击后想出了这个。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。此示例基于官方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

阐述OneOfOne的~/.netrc答案，这就是我在Linux上使用Jenkins所做的事情：

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，因此docker可以在Dockerfile中使用它们。

RUN的第一行和最后一行创建并删除~/.netrc。

在Jenkins中，我在构建命令中使用git pull中相同的信用。

在此策略中，密码不会在泊坞窗构建过程中回显，也不会保存在泊坞窗图像的任何图层上。另请注意，在构建期间，银杏测试结果将打印到控制台。

Answer 4

最新版本的golang（v1.11）中现在有modules。

引用来源：

模块是一组相关的Go软件包的集合，这些版本一起作为一个单元进行了版本控制。通常，单个版本控制存储库恰好对应于单个模块。

使用最新版本的golang将使您拥有私有存储库中的依赖项。本质上，通过运行$ go mod vendor命令将在本地为所有外部依赖项创建一个vendor目录。现在，确保您的Docker映像具有Golang v1.11，您将使用以下内容更新Dockerfile：

WORKDIR /<your repostiory>

COPY . ./
