Answer 1

As @iliefa mentioned in his comment above, the below part of the definition is treated as labels in this type of cases.

ports:
    - port: 80
      name: http

In your scenario, we need to either remove 'name: http' as mentioned by @iliefa or we need to add 'name: http' under 'ports:' in the service definition as you can spot below.

apiVersion: v1
kind: Service
metadata:
  name: dummy-svc
  labels:
    app: nginx
spec:
 ports:
    - protocol: TCP
      port: 80
      targetPort: 80
      name: http
