Defining a fallback service for Kubernetes ingress

0 votes

How do I present a “website down” message to the visitors if all the pods are crashed?

Right now a page appears with the error message “default backend-404”

I’ve tried a few things but nothing is working.

I’ve tried something like this

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: example-ingress
spec:
  backend:
    serviceName: website-down-service
    servicePort: 80
  rules:
    - host: example.com
      http:
        paths:
          - path: /
            backend:
              serviceName: example-service
              servicePort: 80

What am I supposed to do?

For the Nginx Ingress Controller there is a flag --default-backend-service, which currently points to the service showing the "default backend - 404" message. Just replace it with the service you want.
