Odoo 15.0 longpolling behaviour behind GKE Ingress Load balancer

Question

I tried installing Odoo inside GKE, and expose the service via GKE Ingress Load Balancing

I keeps getting 502 from /longpolling/poll after 50s, but when i simulate live chat going in and out, the /longpolling/poll return 200, when no chat coming in/out it returns 502 again

this is my odoo.conf

my ingress yaml is :

apiVersion: networking.k8s.io/v1
kind: Ingress

  annotations:
    ingress.gcp.kubernetes.io/pre-shared-cert: ssl-odoo
    kubernetes.io/ingress.class: gce

  labels:
    app: odoo-ingress
    app.kubernetes.io/component: odoo-ingress
    app.kubernetes.io/instance: odoo-ingress
  name: odoo-ingress
  namespace: odoo

    http:
      paths:
      - path: /longpolling 
        pathType: Prefix
        backend:
          service:
            name: odoolp-cls-service # tried with dedicated or same as / 
            port:
              number: 8072
      - path: / 
        pathType: Prefix
        backend:
          service:
            name: odoo-cls-service
            port:
              number: 8069

i tried using docker instead of GKE, /longpolling/poll return 200 even when there is no live chat activity

i want to use GKE ingress so that i can integrate with the Google Managed Certificate which afaik not going to work with nginx pod

Anyone have a suggestion please

Answer 1

it turns out Odoo /longpolling/poll takes 50s to finally respond, but the default timeout on ingress on GKE is 30s, after changing the timeout on GKE LB ingress to 60s the browser get HTTP 200
