Class not found: io.kubernetes.client.openapi.models.V1Service

I get the following error when trying to use the YAML file from my GitRepo to deploy to kube cluster. Console errors

Here is the content of my .yaml file:

apiVersion: v1
kind: Service
metadata:
  name: ts-service
spec:
  type: NodePort
  selector:
    app: ts
  ports:
  - protocol: TCP
    port: 8080
    nodePort: 8080

---

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ts-deployment
  labels:
    app: ts
spec:
  replicas: 2
  selector:
    matchLabels:
      app: ts
  template:
    metadata:
      labels:
        app: ts
    spec:
      containers:
      - name: ts
        image: $DOCKER_IMAGE_NAME:$BUILD_NUMBER
        ports:
        - containerPort: 8080

I've already tried changing the ports, the API version to apps/v1, etc. What seems weird to me is that no matter which line goes foirst in the file, it always shows me the same issue. What can be causing this?

Solution

  • I found the root cause of this behaviour. Jackson 2 API plugin version 2.11.1 is breaking kube deployments; you can find more info by the link below:
    https://issues.jenkins-ci.org/browse/JENKINS-62995

    Downgrading the following plugins worked for me: Jackson 2 API v2.10.0,
    Kubernetes v1.21.3,
    Kubernetes Client API v4.6.3-1,
    Kubernetes Continuous Deploy v2.1.2,
    Kubernetes Credentials v0.5.0

    As those plugins are default, you would need to find the relevant version source files in https://plugins.jenkins.io/, and upload them to your Jenkins server by going
    Manage Jenkins --> Manage Plugins --> Advanced --> Upload Plugin section
