metadata:
  name: jeffspace
---
apiVersion: v1
kind: Service
metadata:
  name: jeffnet
  namespace: jeffspace
---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/service-upstream: "true"
    nginx.ingress.kubernetes.io/upstream-vhost: jeffnet.jeffspace.svc.cluster.local
  name: jeffnet-ingress
  namespace: jeffspace
spec:
  ingressClassName: nginx-int
  rules:
  - host: api.jeff.net
    http:
      paths:
      - backend:
          service:
            name: jeffnet
            port:
              number: 80
        path: /
        pathType: Prefix
