I'm trying to run a container that will expose a golang service from a package that I have on a private GitHub repo.

Since I am working with GCE, my starter image is google/debian:wheezy.

After installing all the required dependancies and tools, I am running 

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

where the package is a private repo.

I have added my GitHub SSH keys to allow the cloning from the private repo to the docker file:

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

Still, I am getting an error during the go get process when go tried to clone the repo:

# 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

To debug the problem, from the Dockerfile, I am running:

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

And this tells me there are some problems. It looks like validating the private key is OK but something weird is going on the the public key. This is the complete ssh-keyscan result:

I have tried chmod 600 and chmod 700 on the priv/public keys, this did not help.

Any clues? Has anyone succeeding in running go get that fetches from private repos on debian from docker?

经过一番折腾，我弄清楚了这一点。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。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

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

详细说明 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 .

这两个ARG指令映射--build-args 以便 docker 可以在 Dockerfile 中使用它们。

RUN创建和删除的第一行和最后一行~/.netrc。

在 Jenkins 中，我在构建命令中使用来自 git pull 的相同凭据。

在此策略中，密码不会在 docker 构建过程中回显，也不会保存在 docker 映像的任何层上。另请注意，在构建过程中，银杏测试结果会打印到控制台。

在最新版本的 golang (v1.11) 中，现在有modules。

引用来源：

模块是相关 Go 包的集合，它们作为一个单元一起进行版本控制。大多数情况下，单个版本控制存储库完全对应于单个模块。

使用最新版本的 golang 将允许您拥有位于私有存储库中的依赖项。本质上，通过运行该 命令将为所有外部依赖项在本地$ go mod vendor创建一个目录。vendor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 . ./

我在 Github 中遇到了这个问题，我使用以下方法修复它personal access token：

首先，请ARG用于您的 Dockerfile vars(inputs)：

之后使用 github 个人访问令牌配置您的 git

GITHUB_PAT -> github 个人访问令牌

FROM golang:1.17 as builder

ARG GITHUB_PAT

WORKDIR /your-app
COPY go.mod .
COPY go.sum .
RUN git config --global url."https://${GITHUB_TOKEN}:x-oauth-basic@github.com/".insteadOf "https://github.com/"
RUN go mod download
COPY . .
RUN go build -ldflags '-w -s' -o ./out ./main.go


FROM golang:1.17

WORKDIR /app

COPY --from=builder /your-app/out ./
WORKDIR /app/

ENTRYPOINT [ "./out" ]
