Docker VotingApp在Kubernetes上构建/发布Jenkins并不是幂等的

Question

我尝试使用Docker投票应用程序通过Jenkins在Kubernetes上进行部署。我使用Azure容器注册表作为docker镜像的存储库。在第一次尝试时，所有部署都正常：

当我重新运行管道而不更改某些内容时，我收到以下错误：

Redis服务定义：

＆＃13;

＆＃13;

---
apiVersion: v1
kind: Service
metadata:
  creationTimestamp: null
  labels:
    app: redis
    version: alpine
  name: redis
  selfLink: /api/v1/namespaces//services/redis
spec:
  clusterIP: 
  ports:
  - name: 
    port: 6379
    protocol: TCP
    targetPort: 6379
  selector:
    app: redis
    version: alpine
  sessionAffinity: None
  type: ClusterIP
status:
  loadBalancer: {}
---

＆＃13;

＆＃13;

＆＃13;

docker图像是使用＆＃34;最新版本＆＃34;标签。

＆＃13;

＆＃13;

stage 'Checkout'
node {
    git 'https://github.com/*****/example-voting-app.git' // Checks out example votiung app repository
   stage 'Docker Builds'
   docker.withRegistry('https://*****.azurecr.io', 'private-login') {
        parallel(
            "Build Worker App":{def myEnv = docker.build('*****.azurecr.io/example-voting-app-worker:latest', 'worker').push('latest')},
            "Build Result App":{def myEnv = docker.build('*****.azurecr.io/example-voting-app-result:latest', 'result').push('latest')},
            "Build Vote App":{def myEnv = docker.build('*****.azurecr.io/example-voting-app-vote:latest', 'vote').push('latest')}
            )
    }
    stage 'Kubernetes Deployment'
    sh 'kubectl apply -f kubernetes/basic-full-deployment.yml'
    sh 'kubectl delete pods -l app=vote'
    sh 'kubectl delete pods -l app=result'
    stage 'Smoke Test'
    sh 'kubectl get deployments'
}

您的定义包含由apiserver自动生成/管理的字段。其中一些是在创建对象时创建的，之后无法更新。 从文件中删除以下字段以使其满意：

metadata:
  creationTimestamp: null
  selfLink: /api/v1/namespaces//services/redis
status:
  loadBalancer: {}
