You can make this accessible via ngrok with the following manifest:
--------------------------------------------------------------------------------
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: test-app-1
  namespace: default
spec:
  ingressClassName: ngrok
  rules:
  - host: test-app-1-s3gmyzci.ngrok.app
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: test-app-1
            port:
              number: 80
--------------------------------------------------------------------------------
Applying this manifest will make the service "test-app-1"
available on the public internet at "https://test-app-1-s3gmyzci.ngrok.app/".
