Running Meteor app with Nginx SSL proxy on Kubernetes
<p>I have a Meteor app deployed using Kubernetes on Google Cloud, configured with Nginx acting as SSL termination. Everything working ok.</p>

<p>However, it appears that if two different clients connect to two different SSL containers, updates don't show up on the respective apps for up to 10 seconds, which makes it seem that Websockets isn't working, but polling is taking effect. I have confirmed that all clients are connected with Websockets, but since updates do not propagate immediately, perhaps Nginx isn't configured to correctly talk with the Meteor app.</p>

<p>Here's my SSL/Nginx service:</p>

<p><code>apiVersion: v1
kind: Service
metadata:
  name: frontend-ssl
  labels:
    name: frontend-ssl
spec:
  ports:
  - name: http
    port: 80
    targetPort: 80
  - name: https
    port: 443 
    targetPort: 443 
  selector:
    name: frontend-ssl
  type: LoadBalancer
  loadBalancerIP: 123.456.123.456
  sessionAffinity: ClientIP
</code></p>

<p>And here is the Meteor service:</p>

<p><code>apiVersion: v1
kind: Service
metadata:
  name: frontend
  labels:
    name: frontend
spec:
  ports:
  - port: 3000
    targetPort: 3000
  selector:
    name: flow-frontend
  type: LoadBalancer
  loadBalancerIP: 123.456.123.456
  sessionAffinity: ClientIP
</code></p>

<p>For SSL termination, I'm using the Kubernetes suggested SSL setup forked with Websockets additions <a href="https://github.com/markoshust/nginx-ssl-proxy" rel="nofollow noreferrer">https://github.com/markoshust/nginx-ssl-proxy</a></p>
