Theia on Kubernetes. Help with nginx reverse proxying

[rishi1111]

Hello, I am trying to setup theia on k8s

My k8s ingress looks like this

---

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: code-server
namespace: default
annotations:
'kubernetes.io/ingress.class': 'nginx'
'nginx.ingress.kubernetes.io/configuration-snippet': |
rewrite ^/theia/(.*)$ /$1 break;
proxy_set_header Host $host;
spec:
rules:

• host: example.com
  http:
  paths:
  • path: /theia
    backend:
    serviceName: theia-svc
    servicePort: 80

example.com/theia -> should redirect to the pod which has theia running on localhost:3000

With the above configuration it opens up the page but websocket connections do not work.

Does anyone have any experience with this.
