Jenkins 中的未知阶段部分 "withKubeConfig"

Question

我将使用 jenkins CICD 将我的 docker 映像部署到 k8s 集群。

我在 Jenkins 中安装了 Kubernetes CLI 和 SSH Agent。

我使用了下面的代码。

stage('List pods') {
    withKubeConfig([credentialsId: 'kubectl-user']) {
        sh 'curl -LO "https://storage.googleapis.com/kubernetes-release/release/v1.20.5/bin/linux/amd64/kubectl"'  
        sh 'chmod u+x ./kubectl'  
        sh './kubectl get pods -n dev'
    }
  }

而且，我收到以下错误。

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 39: Unknown stage section "withKubeConfig". Starting with version 0.5, steps in a stage must be in a ‘steps’ block. @ line 39, column 2.
    stage('List pods') {
    ^

WorkflowScript: 39: Expected one of "steps", "stages", or "parallel" for stage "List pods" @ line 39, column 2.
    stage('List pods') {
    ^

2 errors

我错过了什么吗？

您似乎在声明性管道中使用 scripted pipeline syntax，因此您看到了错误。

如果您想使用声明性管道语法，则必须严格遵守 formatting guidelines，在您的情况下，您缺少 stage 指令下的 steps 指令。
您的代码应该类似于：

pipeline {
    agent any
    stages {
       stage('List Pods') {
           steps {
               withKubeConfig([credentialsId: 'kubectl-user']) {
                   sh 'curl -LO "https://storage.googleapis.com/kubernetes-release/release/v1.20.5/bin/linux/amd64/kubectl"'
                   sh 'chmod u+x ./kubectl'
                   sh './kubectl get pods -n dev'
               }
           }
       }
    }
}

如果您想使用脚本化的管道语法，它将类似于：

node {
    stage('List Pods') {
        withKubeConfig([credentialsId: 'kubectl-user']) {
            sh 'curl -LO "https://storage.googleapis.com/kubernetes-release/release/v1.20.5/bin/linux/amd64/kubectl"'
            sh 'chmod u+x ./kubectl'
            sh './kubectl get pods -n dev'
        }
    }
}
