How can I set rx.Config to deploy self-hosting on Kubernetes (GKE)?

[ppippi-dev]

Hi, I have some questions.

I want to deploy my app on Kubernetes using self-hosting.

But I have some problems.

My problem is this:

When I set the ingress as blah.blah.com, the pod is okay, but I can't find the backend server. I receive this error message:

Cannot connect to server: timeout. Check if server is reachable at ws://blah.blah.com:8000/_event

It's not the situation that I expected, I expected to route to http://localhost:8000/_event

However, when I set the api_url value and ingress to "http://blah-api.blah.com", it works well.

Why does it route to ws://blah.blah.com:8000/_event when I set api_url to http://localhost:8000?

I attaching my kubernetes deployment's code and python reflex rxconfig code

          env:
            - name: API_URL
              value: "http://localhost:8000"
            - name: DEPLOY_URL
              value: "http://localhost:3000"
          command: ["sh", "-c", "poetry run reflex run --env prod"]
          ports:
            - name: http
              containerPort: 3000
              protocol: TCP
            - name: api
              containerPort: 8000
              protocol: TCP

config = rx.Config(
    app_name="blahblah",
    api_url=os.getenv("API_URL", 'http://localhost:8000'),
    deploy_url=os.getenv("DEPLOY_URL", 'http://localhost:3000'),
    backend_host=os.getenv("BACKEND_HOST", '0.0.0.0'),
)
