Use defaultbackend docker image feature in Kong Ingress like Nginx


We would like to use a Docker Image (stored in an Azure Container Registry) that contains a custom maintenance page, which will be redirected from the Kong Ingress, if the application k8s Pods (upstream service) are not running, so no endpoints can be found.

Nginx has this configuration as per this code block → ingress-nginx/values.yaml , which we use currently in some AKS clusters.

We are using Helm Release of Kong Ingress version “2.30.0”.

Is there is something similar configuration to Kong Ingress, (e.g. a plugin) ? I haven’t found anything similar to this nginx configuration either with a plugin, or on Kong Helm Values.
