jenkins - GitHub Action 触发无法连接 jenkins

Question

我正在尝试使用以下工作流文件通过 GitHub Action 触发 jenkins 构建

name: Trigger Jenkins Build [ Backend ]
on:
  pull_request:
    branches: [ master ]
    types: [ closed ]
env:
  JENKINS_HOST: "http://jenkins.example.net:8080/"
  JENKINS_JOB: "job/Backend/"
  JENKINS_SECURITY_GROUP_ID: "sg-#####"
jobs:
  trigger:
    name: Triggering Jenkins Build
    runs-on: ubuntu-latest
    steps:
    - name: Add public IP to AWS security group
      uses: sohelamin/aws-security-group-add-ip-action@master
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: 'us-west-2'
        aws-security-group-id: ${{ env.JENKINS_SECURITY_GROUP_ID }}
        port: '8080'
        to-port: ''
        protocol: 'tcp'
        description: 'GitHub Action'
    - name: Triggering Jenkins Build [ Backend ]
      if: github.event.pull_request.merged == true
      uses: GoldenspearLLC/build-jenkins-job@master
      with:
        jenkins-url: ${{ env.JENKINS_HOST }}
        user: ${{ secrets.JENKINS_USER }}
        jenkins-token: ${{ secrets.JENKINS_USER_TOKEN }}
        job-path: ${{ env.JENKINS_JOB }}
        job-params: "{'FRESH_BUILD':'True', 'BUILD_BRANCH':'master', 'DEPLOY_DEV':'True', 'DEPLOY_QA':'False, 'DEPLOY_STAGING':'False, 'DEPLOY_PRODUCTION':'False'}"

但是 Github Action 因 Triggering Jenkins Build [Backend] 失败并出现以下错误

Run GoldenspearLLC/build-jenkins-job@master

在构建运行期间，我可以看到步骤 sohelamin/aws-security-group-add-ip-action@master 将 IP 添加到安全组并在最后删除。

为什么它尝试连接 port=80 而不是 port=8080

我在这里缺少什么？

Answer 1

报错说明你在Jenkin域中错误:http://jenkins.example.net:8080/将其替换为您正确的域

错误消息:“socket.gaierror: [Errno -2] Name or service not known” 表示您的程序无法连接到此域，因为它不存在或 DNS 无法解析
