来自 Jenkins 管道的 Git 使用错误的 SSH 私钥推送回 Git 存储库

Question

我正在拉取一个公共 git 存储库，我正在尝试使用 denpal(SSH 私钥)凭据将我的更改推送回存储库。

stages {
stage('Git clone') {
steps {
git branch: 'feature/Jenkinsfile',
credentialsId: 'denpal',
url: '[e-mail]:test/denpal.git'
}
}
stage('Test Git') {
steps {
withCredentials([sshUserPrivateKey(credentialsId: 'denpal', keyFileVariable: 'SSH_KEY')]) {
sh '''
git commit --allow-empty -m "test withCredentials"
git push origin feature/Jenkinsfile
'''
}
}
}

不幸的是，这给出了以下错误：

> git --version # timeout=10
using GIT_SSH to set credentials denpal
> git fetch --tags --force --progress [e-mail]:test/denpal.git +refs/heads/*:refs/remotes/origin/*
> git rev-parse refs/remotes/origin/feature/Jenkinsfile^{commit} # timeout=10
> git rev-parse refs/remotes/origin/origin/feature/Jenkinsfile^{commit} # timeout=10

[Pipeline] // withCredentials  

我也试过这个，但这也失败了：

withCredentials([sshUserPrivateKey(credentialsId: 'denpal', keyFileVariable: 'private_key', passphraseVariable: '', usernameVariable: 'git')]){ 

知道我做错了什么吗？

Answer 1

withCredentials()和sshUserPrivateKey行将私钥写入临时文件并将位置分配给$SSH_KEY，但它没有被使用，因为之后没有引用$SSH_KEY。

您可以使用$GIT_SSH_COMMAND(docs) 告诉 ssh 和 git 私钥文件。

取代：

git push origin feature/Jenkinsfile

跟：

GIT_SSH_COMMAND="ssh -i $SSH_KEY" git push origin feature/Jenkinsfile

Answer 2

上面对Rob 答案的更全面的描述，让 git checkout 在 Jenkins 声明式管道语法上使用子模块。

#!/usr/bin/env groovy
pipeline {
agent any
stages {
stage ('Clone') {
steps {
checkout scm
withCredentials([sshUserPrivateKey(credentialsId: 'bitbucket_ssh', keyFileVariable: 'SSH_KEY')]) {
sh 'GIT_SSH_COMMAND="ssh -i $SSH_KEY" git submodule update --init'
}
}
}
...
}
}

这是 https://issues.jenkins.io/browse/JENKINS-20941 的解决方法
