Custom behavior for the situation when the service has no healthy instances

[VladyslavLishchyna]

Hello everyone, please forgive me right away if my question is stupid or the answer has already been written before (I can’t find it, but I was looking for it). Is it possible in fabio to set a route to which the request will be redirected if there are no available services?

I mean the situation when services are registered for a certain path, but they have the status "unhealthy". In such a situation, I would like to redirect requests to a static page with information like "technical work is in progress, try again later".

Is there a way to do this with consul+fabio ?

You can do this using the weight feature ...
Implementation discussion here: #42
Docs here: https://fabiolb.net/cfg/

TLDR: Set w=100 on your consul services and register a fallback with w=0 the 0 service will only get traffic if the others are down.
