I'm trying out deployments on Kubernetes via Jenkins with the Docker Voting App. I use the Azure Container registry as a repository for the docker images. On first try all is deployed ok:

When I re-run the pipeline without changing something I get the following error:

Redis service definition:

apiVersion: v1
kind: Service
metadata:
  creationTimestamp: null
  labels:
    app: redis
    version: alpine
  name: redis

spec:

  ports:

  selector:

    version: alpine
  sessionAffinity: None
  type: ClusterIP

The docker images are build with "latest" tag.

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'
}
