Question

我正在运行jenkins作业来构建我们的Maven应用程序并将其部署到kubernetes集群中。我已按顺序创建了pod容器模板来部署模块。

当我要构建我的詹金斯工作时，构建失败并出现以下错误，

Still waiting to schedule task
‘Jenkins’ doesn’t have label ‘Angular_71-bt2f0’

同时，当我检查kubernetes master时，我能够看到pod正在尝试调度，并且几秒钟后它又回到了终止状态。

root@poc:/var/run# kubectl get pods
NAME                           READY   STATUS              RESTARTS   AGE
angular-71-bt2f0-ns772-4rmrq   0/3     ContainerCreating   0          1s

root@poc:/var/run# kubectl get pods
NAME                           READY   STATUS        RESTARTS   AGE
angular-71-bt2f0-ns772-4rmrq   2/3     Terminating   0          28s
angular-71-bt2f0-ns772-mcv9z   2/3     Error         0          8s

管道脚本

def label = "worker-${UUID.randomUUID().toString()}"

podTemplate(containers: [
    containerTemplate(name: 'maven', image: 'maven:3.3.9-jdk-8-alpine', ttyEnabled: true, command: 'cat'),
    containerTemplate(name: 'golang', image: 'golang:1.8.0', ttyEnabled: true, command: 'cat')
  ]) {

    node(POD_LABEL) {
        stage('Get a Maven project') {
            git 'https://github.com/jenkinsci/kubernetes-plugin.git'
            container('maven') {
                stage('Build a Maven project') {
                    sh 'mvn -B clean install'
                }
            }
        }
    }
  }

请找到以下主机配置

root@poc:~# kubectl get svc
NAME         TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)          AGE
kubernetes   ClusterIP   10.96.0.1     <none>        443/TCP          2d

kubectl错误日志

kubectl logs angular-71-bt2f0-ns772-4rmrq 

error: a container name must be specified for pod angular-77-l32fr-sfxqk-qhdgf, choose one of: [maven golang jnlp]

Below is the kubectl logs while running jenkins job

root@poc:~# kubectl logs angular103f578nkcrnfx69fk c maven
Error from server (NotFound): pods "angular103f578nkcrnfx69fk" not found

root@poc:~# kubectl logs angular103f578nkcrnfx69fk c golang

root@poc:~# kubectl logs angular103f578nkcrnfx69fk c jnlp
Error from server (NotFound): pods "angular103f578nkcrnfx69fk" not found

请问有人可以帮助我解决此问题，我不确定我在哪里做错了。

Answer 1

因为kubectl -n jenkins-namespace get services显示为：

NAME                 TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)     AGE
cicd-jenkins         ClusterIP   172.20.120.227   <none>        8080/TCP    128d
cicd-jenkins-agent   ClusterIP   172.20.105.189   <none>        50000/TCP   128d

您必须转到Jenkins>管理Jenkins>配置系统（http://jenkins:8080/configure）。然后，相应地配置 Jenkins URL 和 jenkins隧道（请参见下面的屏幕截图）

如果您使用的是Jenkins代码配置（JCasC）插件，则可以通过jenkinsUrl和jenkinsTunnel键进行配置：

jenkins:
  clouds:
  - kubernetes:
      name: cluster
      serverUrl: https://kubernetes.default
      # ....
      jenkinsUrl: http://cicd-jenkins:8080/
      jenkinsTunnel:  cicd-jenkins-agent:50000
      # ....

Answer 2

也许您缺少一些东西？

下面的containerTemplates是真正的管道任务，您的jenkins从属代理（JNLP）容器在哪里？

private fun moveToFront(mainAppPackage: String) {
    val activityManager = getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
    val recentTasks = activityManager.getRunningTasks(Int.MAX_VALUE)//activityManager.appTasks.map { it.taskInfo }
    for (i in recentTasks.indices) {
        log("PUSH Application executed : "
                + recentTasks[i].baseActivity.toShortString()
                + "\t\t ID: " + recentTasks[i].id + "")
        if (recentTasks[i].baseActivity.toShortString().indexOf(mainAppPackage) > -1) {
            log("PUSH TO FRONT : "
                    + recentTasks[i].baseActivity.toShortString()
                    + "\t\t ID: " + recentTasks[i].id + "")
            activityManager.moveTaskToFront(recentTasks[i].id, ActivityManager.MOVE_TASK_WITH_HOME)
        }
    }
}

Jenkins无法创建kubernetes POD
