Jenkins无法创建kubernetes POD

Question

我正在运行 jenkins 作业来构建我们的 maven 应用程序并部署到 kubernetes 集群中。为此，我创建了 Pod 容器模板来部署我的模块。

当我运行构建我的jenkins作业时，我的构建失败，出现以下错误，

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

与此同时，当我检查kubernetes主服务器时，我可以看到pods正在尝试调度，并且在几秒钟后返回到终止状态。

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'
                }
            }
        }
    }
  }

请在下面找到主机配置

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
Error from server (NotFound): pods "angular103f578nkcrnfx69fk" not found

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

你能请有人帮我解决这个问题吗，我不确定我在这里做错了哪里。

Answer 1

也许你缺少一些？？

由于下面的容器模板是真正的管道任务，您的jenkins从属代理(JNLP)容器在哪里？

...
    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')
...
``

Answer 2

因为，< code > ku bectl-n Jenkins-namespace get services 显示:

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

你得去Jenkins

如果您使用的是Jenkins Configuration as Code（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
      # ....
