We have been building an ingress Nginx compatibility layer in Traefik that supports the most used ingress Nginx annotations. You should definitely give it a try as it makes Traefik a drop-in replacement to ingress Nginx, without touching your existing ingress resources. Your feedback will be super useful to make it better

This is pretty funny. The main reason I dislike Traefik is because you can get away with broken ingress objects (i.e. you put elements into the `tls` array that only have a cert or only have a hostname and traefik will do some fuzzy matching) and it was a huge pain to get our manifest rendering pipeline back to spec.

This whole discussion needs way more input - this has been posted three times (I was the last and it got flagged as "dupe") - the moderators are not allowing fair discussion here.

As an industry this has a huge impact.

Good to know re: Traefik - I wonder if K3s will continue to ship Traefik v2?
