I created a Kubernetes-cluster with a deployment + service (LoadBalancer) for a SpringBoot-Java-App. If I want to access the Web-App via the external IP, I get a timeout error. Does anybody now how to fix this?
LoadBalancerService.yml:
apiVersion: v1
kind: Service

creationTimestamp: null
labels:
app: webapp
name: webapp
spec:
ports:
- name: 8080-8080

targetPort: 8080

Deployment.yml
apiVersion: apps/v1
kind: Deployment

Solution: disable the Firewall ;)
