Docker:从私人GitHub仓库获取

奋斗中DU_536 发布于 2022-12-18 17:01

容器

我正在尝试运行一个容器,它将从我在私有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.

安装所有必需的依赖项和工具后,我正在运行

RUN go get github.com//

包裹是私人回购的地方.

我添加了我的GitHub SSH密钥以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

在尝试克隆回购时,我在go get过程中遇到错误:

# cd .; git clone https://github.com// /gopath/src/github.com//
Cloning into '/gopath/src/github.com//'...
fatal: could not read Username for 'https://github.com': No such device or address
package github.com//: exit status 128

要调试问题,从Dockerfile,我正在运行:

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.

有线索吗？有没有人成功运行从docker的debian私人回购获取？

经过一番黑客攻击后,我想出了这个.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.这个例子基于官方的Docker golang图像(Debian Wheezy):

与您的示例的主要区别在于您需要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

爱是种承诺ml

go get 正试图使用https,完全忽略ssh.

你必须设置~/.netrc:
```
ADD priv/.netrc /root/.netrc
```
netrc看起来像:
```
machine github.com login github-username password github-password
```

详细阐述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命令为：

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，因此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build命令中使用了git pull中的相同凭据。

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。还要注意，在构建过程中将银杏测试结果打印到控制台。
