Hi! Your guidance is greatly appreciated.
I’m running minikube version: v1.22.0 on macOS.

After creating the POD (yaml file below), It installs fine. After creating the service: kubectl create -f voting-app-service.yaml
I get the following error:

“error: error validating “voting-app-service.yaml”: error validating data: ValidationError(Service.metadata): unknown field “app” in io.k8s.apimachinery.pkg.apis.meta.v1.ObjectMeta; if you choose to ignore these errors, turn validation off with --validate=false”

Below are the yaml files used. Any idea what’s going on?

voting-app-pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: voting-app-pod
labels:
name: voting-app-pod
app: demo-voting-app
spec:
containers:

  • name: voting-app
    image: kodekloud/examplevotingapp_vote:v1
    ports:
    • containerPort: 80

voting-app-service.yaml
apiVersion: v1
kind: Service
metadata:
name: voting-service
labels:

Tej_Singh_Rana:
I formatted correctly. So above YAMLs will work.

Tej_Singh_Rana:
Space required under the service.metadata.labels
