这是我的声明性 Jenkinsfile 的一个子集：

pipeline {
    agent {
      kubernetes {
        yamlFile 'pod.yml'
        defaultContainer 'tools'
      }
    }
    stages {
        stage('Init') { // <- this stage executes in Kubernetes and works very well
            steps {
                sh "echo init"
            }
        }
        stage('Build') {
            agent { label 'B202981' } // <- This wont work; B202981 is computer on my network
            steps {
                sh "echo build"
            }
        }
    }
}

当此管道运行时，它会因异常而失败，您可以在此处看到该异常，而谷歌搜索此异常对我没有帮助。
