I recently encountered a problem where my Kubernetes resources weren’t showing the same outage page as my regular EC2 resources. I realized this was because of ingress-nginx.

There are a few solutions out there suggesting deploying a docker container to show the error page required, but that was overkill for me.

I’ve found that the easiest way to create a custom error page, is by adding something similar to the below to your ingress object:

apiVersion: extensions/v1beta1
kind: Ingress
    nginx.ingress.kubernetes.io/server-snippet: |
      location @custom_503 {
        return 503 "<html> <head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8'> <style>...</style> </head> <body> <div class='container'> <div class='content'> <div class='title'> We apologise for the inconvenience. </div><div class='title'> Please try again in 10 minutes. </div><div> <p> We work hard to make xx the world's best xx software. Occasionally, downtime is required to deliver new features and improvements to you. </p></div></div></div></body></html>";
      error_page 503 @custom_503;
