Re: [kubernetes-users] Weighted load balancing to service/pods

2017-08-06 Thread Guang Ya Liu 
I think the istio  can help you for such case, checkout
here https://istio.io/docs/concepts/traffic-management/request-routing.html
for detail, hope this helps!

Re: [kubernetes-users] Weighted load balancing to service/pods

2017-08-05 Thread 'Tim Hockin' via Kubernetes user discussion and Q 
As far as I know, nobody has implemented this, but it should be pretty
trivial to write your own controller to manipulate labels based on your own
definition of availability.

Maybe with some other ingress back end (doubt it). Also, don't think this
can be achieved with service either :-(

So, I don't see any other way than istio, that issue I posted or deploy an
nginx with that config. But maybe I'm missing something.

I **guess** there is not:
https://github.com/kubernetes/kubernetes/issues/25485

Maybe with some other ingress back end (doubt it). Also, don't think this
can be achieved with service either :-(

So, I don't see any other way than istio, that issue I posted or deploy an
nginx with that config. But maybe I'm missing something.
