Docker:从私人GitHub存储库获取

我正在尝试运行一个容器,它将从我在私有GitHub repo上的一个包中公开一个golang服务。
由于我在使用GCE,我的启动图像是google/debian:wheezy。
在安装了所有必需的依赖项和工具之后,我正在运行

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

其中该包是私有回购。
我已经添加了我的GitHub SSH密钥,以允许从私有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

尽管如此,在go get过程中,当go试图克隆repo时,我还是收到了一个错误:


# 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

要调试问题,请从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。看起来验证私钥是可以的,但是在公钥上发生了一些奇怪的事情。这是完整的ssh-keyscan结果:

我试过在私钥/公钥上使用chmod 600和chmod 700,但没有帮助。
有什么线索吗?有没有人成功运行go get,从docker的debian上的私有repos中获取?

我在黑客攻击之后发现了这一点。这不是一个理想的解决方案,因为它涉及到安装SSH,以及在容器中构建私钥。这个例子基于官方的Docker golang image(Debian Wheezy):
与示例的主要区别在于,您需要使用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正在尝试使用https,完全忽略ssh。
您必须设置~/.netrc

ADD priv/.netrc /root/.netrc

其中netrc类似于:

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

参考:

在golang的最新版本(v1.11)中,现在有modules
引用来源:
一个模块是一组相关的Go语言包的集合,这些包作为一个单元被版本化,通常一个版本控制库对应一个模块。
使用最新版本的golang将允许您拥有私有仓库中的依赖项。实际上,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您的Docker文件:

WORKDIR /<your repostiory>

COPY . ./
fumotvh3

fumotvh34#

详细说明OneOfOne的~/.netrc答案,这是我在Linux上对Jenkins所做的:

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 的建造命令是:

docker build \
    --build-arg GITHUB_USER=xxxxx \
    --build-arg GITHUB_PASS=yyyyy \
    -t my-project .

这两个ARG指令Map--build-arg,以便Docker可以在Docker文件中使用它们。
RUN的第一行和最后一行创建和删除~/.netrc
在Jenkins中,我在build命令中使用了来自git pull的相同creds。
在这个策略中,密码在docker构建过程中不会被回显,也不会被保存在docker映像的任何层上。还要注意的是,ginkko测试结果在构建过程中会被打印到控制台。

我在Github中遇到了这个问题,我使用personal access token修复了它:
首先,请使用ARG作为您的Dockerfile变量(输入):
然后用github个人访问令牌配置你的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_PAT}: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" ]
