Enable session affinity for canary release with nginx ingress controller

Question

I'm trying to setup canary-release with Nginx ingress controller. The problem is that it doesn't keep session affinity causing every request to be served by a random service.

My canary ingress:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  namespace: canary
  name: ingress-nginx
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/canary: "true"
    nginx.ingress.kubernetes.io/canary-weight: "50"

My default ingress:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-nginx
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/affinity: cookie

Is it currently possible to enable session affinity for canary release with Nginx ingress?

Seems you are not the only who have this problem. There is an open issue on github with mostly the same problem: Session affinity doesn't work for canaries

Waiting for fix
