I’m trying to achieve zone awareness configuration (to avoid inter az costs).
- each worker has metadata with his AZ
- created service subset per AZ and one default service subset that contains all service az.
- route to the appropriate subset is done by HTTP POST.
That’s how I can query workers from a specific AZ/all AZs.
If all workers in the service subset are down, I want to be redirected to the default service subset instead I’m getting “no upstream available”.
Is there an option to config fallback to the default service subset?
