This is a custom default backend for nginx-ingress. The only reason for creating this project was to customize the 404 page and provide a better (and branded) user experience.
By default, the backend will listen on port 9090 and serve an HTML page with the error file at /assets/404.html. Override the default html page by mounting a config map with the html page at a different path.
Important Note
The final image is based on scratch image, so normal file system operations won't work. See the Dockerfile for more details
