声明式詹金斯管道完成阶段后如何保持流程运行

问题描述

pipeline {
  agent none
  stages {
   stage('Server') {
      agent{
          node {
            label "xxx"
            customWorkspace "/home/xxx/server"
          }
        }
      
      steps {
        sh 'node server.js &'
        //start server
      }
    }
   stage('RunCase') {
      agent{
          node {
            label 'clientServer'
            customWorkspace "/home/xxx/CITest"
          }
        }

      steps{
        sh 'start test'
        sh  'run case here'
      }
    }
  }

}

我在Jenkins管道上方创建.我想做的是:
1.在服务器节点上启动服务器.
2.在测试节点上开始测试.

I create above Jenkins pipeline. What I want to do is:
1. start server at server node.
2. start test at test node.

但是，我发现第二阶段启动时服务器进程将关闭.因此，如何在第二阶段测试工作完成之前保持服务器启动.我尝试使用&，但仍然无法正常工作.看来这将扼杀我在第一阶段开始的所有过程.

However, I found the server process will be closed when second stage start.So how to keep server start until my second stage testing work is finished. I try to use &, still not working. It seems it will kill all process I started at first stage.

推荐答案

一种解决方案是尝试以并行"模式启动两个阶段.有关更多信息，请参见以下两个文件: parallel-declarative-blog jenkins-pipeline-syntax .但是要小心，因为不能保证第一阶段要在第二阶段开始之前开始.也许您需要等待时间才能进行测试.这是一个Jenkinsfile示例:

One solution is to try to start the two stages in "parallel"-mode. For more informations see this two files: parallel-declarative-blog jenkins-pipeline-syntax. But be carefull, because it is not ensured, that the first stage starts before the second one starts. Maybe you need a waiting time for your tests. Here is an example Jenkinsfile:

pipeline {
agent none
stages {
    stage('Run Tests') {
        parallel {
            stage('Start Server') {
                steps {
                    sh 'node server.js &'
                }
            }
            stage('Run Tests) {
                steps {
                    sh  'run case here'
                }
            }
        }
    }
}
}

另一种解决方案是在后台启动节点服务器.为此，您可以尝试其他工具，例如 nohup 或 pm2 .

Another solution would be to start the node server in the background. For this you can try different tools, like nohup or pm2.
