Custom errors, at least per this example described in the docs here https://kubernetes.github.io/ingress-nginx/examples/customization/custom-errors/

shows a yaml for the desployment to be used as custom-backend https://github.com/kubernetes/ingress-nginx/blob/main/docs/examples/customization/custom-errors/custom-default-backend.yaml

Which uses this image https://github.com/kubernetes/ingress-nginx/blob/c8722b225d06bdeb8385114886549e021c453edd/docs/examples/customization/custom-errors/custom-default-backend.yaml#L39C14-L39C99

and the source code of that image is here https://github.com/kubernetes/ingress-nginx/blob/main/images/custom-error-pages/rootfs/Dockerfile

This info above opens up all available info for someone to analyze for that example custom-error use case.

The info you have provided is too short & succint for anyone to analyze what problem you faced or what is the environment. Does not help much unless you can provide detailed data so that other people do not need to do the homework

Thank You

I wanted to configure custom response headers for my backend ( error pages )

I have configured this using

ingress-nginx/charts/ingress-nginx/values.yaml

Line 56 in 8ca27e7

addHeaders: {}

parameter from values.yaml
