声明式Jenkins管道使用现有的Kubernetes Pod模板 [英] Declarative Jenkins Pipeline use existing Kubernetes Pod Template

问题描述

我正在OpenShift集群中使用OpenShift Jenkins图像.默认的Jenkins映像将导致Jenkins容器被预先配置为指向我的Kubernetes集群.此外，该容器还定义了两个Kubernetes Pod模板，一个用于maven，一个用于nodejs.

I am using the OpenShift Jenkins image within an OpenShift Cluster. This default Jenkins image results in a Jenkins container that is preconfigured to point to my Kubernetes cluster. Additionally, the container has two Kubernetes pod templates defined, one for maven and one for nodejs.

我现在想做的是使用声明性管道并引用这些容器.我尝试了以下

What I would now like to do is use a declarative pipeline and reference these pods. I tried the following

  agent {
     kubernetes {
     //cloud 'kubernetes'
     label 'maven'
     }
  }

但这给出了一个错误提示

But that gives an error stating

org.codehaus.groovy.control.MultipleCompilationErrorsException: 启动失败:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:

WorkflowScript:4:代理类型缺少必需的参数 "kubernetes":containerTemplate @第4行，第10列.

WorkflowScript: 4: Missing required parameter for agent type "kubernetes": containerTemplate @ line 4, column 10.

        kubernetes {

        ^

所有(

All of the (examples) that I can find for declarative pipelines show the pod templates being defined when the agent is specified.

是否可以在声明管道中重用已经定义的模板?

Is it possible to reuse already defined templates in a declarative pipeline?

推荐答案

以下是使用预定义的pod模板的示例.

Here is an example using a pre-defined pod template.

pipeline {
  agent {
      label "maven"
  }
  stages {
    stage('Run maven') {
      steps {
        sh 'mvn -version'
      }
    }
  }
}

您原来的管道定义实际上是在定义一个全新的pod模板，因此该错误强制执行containerTeamplates参数的要求.使用现有模板时，只需在agent块中指定标签.

Your original pipeline definition was in effect defining a brand new pod template and hence the error enforcing the requirement for containerTeamplates parameter. When using an existing template, you can simply specify the label in the agent block.
