ambassador configuration for jupyterlab

Question

I'm trying to replace nginx as proxy with ambassador which is the implementation of the envoyproxy on kubernetes. I did exactly as shown in here

But nothing seems to really works, is there a way someone can help with the appropriated configuration ?

I have a solution.

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: deploy-lab
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: lab
    spec:
      containers:
      - name: ipython-container
        image: <your image>
        imagePullPolicy: "Always"
        ports:
        - containerPort: 8888
        env <if you have one>:
         - name: BASEURL
           value: jupyter
         - name: PASSWORD
           value: jupyter
