Jenkins 管道中的 Git 使用错误的 SSH 私钥推回 Git 存储库

Question

我正在拉取一个公共 git 存储库，并尝试使用 denpal（SSH 私钥）凭据将我的更改推回到存储库中。

stages {
  stage('Git clone') {
    steps {
      git branch: 'feature/Jenkinsfile',
        credentialsId: 'denpal',
        url: 'git@github.com: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，这会产生以下错误：

 > git --version # timeout=10
using GIT_SSH to set credentials denpal
 > git fetch --tags --force --progress git@github.com:test/denpal.git +refs/heads/*:refs/remotes/origin/*

[Pipeline] // withCredentials  

我也尝试过这个，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

andwithCredentials()行将sshUserPrivateKey私钥写入临时文件并将位置分配给，但未使用它，因为之后$SSH_KEY没有引用。$SSH_KEY

$GIT_SSH_COMMAND您可以使用（文档）告诉 ssh 和 git 有关私钥文件的信息。

代替：

git push origin feature/Jenkinsfile

和：

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

Answer 2

对上面 Rob 的答案进行了更全面的描述，让 git checkout 使用 Jenkins 声明性管道语法的子模块。

#!/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'
                }
            }
        }
    ...
    }
}
