jenkins - 在 Jenkins 管道中使用 agent none 定义环境变量

Question

我有一个管道:

#!/bin/groovy

pipeline {
    agent none
    environment {
        agent any
        INSTANCE_NAME = "Jenk"
  }

  stages {
    stage("Print Debug Vars"){
        steps {
            sh 'echo "INSTANCE_NAME is $INSTANCE_NAME"'
        }
    }

    stage("Git Checkout") {
        agent { label 'docker' }
        steps  {
            // ...
            }
      }
    }

    stage("Ansible Galaxy"){
        agent { label 'ansible' }
        steps  {
            // ...
            }
    }
  }
}

问题我，如果我把

agent any

在环境部分，它说:

WorkflowScript: 6: "agent any" is not a valid environment expression. Use "key = value" pairs with valid Java/shell keys. @ line 6, column 5.
       agent any
       ^

WorkflowScript: 5: Expected name=value pairs @ line 5, column 5.
       environment {
       ^

如果我不说，我会得到:

Required context class hudson.Launcher is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node
[Pipeline] // withCredentials
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] End of Pipeline

我该怎么做？

Answer 1

您是否尝试过仅使用具有任何值的代理，例如:

#!/bin/groovy

pipeline {

  agent any

  stages {
    stage("Print Debug Vars"){
        steps {
            sh 'echo "INSTANCE_NAME is $INSTANCE_NAME"'
        }
    }

    stage("Git Checkout") {
        agent { label 'docker' }
        steps  {
            // ...
            }
      }
    }

    stage("Ansible Galaxy"){
        agent { label 'ansible' }
        steps  {
            // ...
            }
    }
  }
}
