Hi again folks, I've setup a k8s deployment with gb & mongo containers and a service which with a public IP that will forward requests to ports withihn those containers. Attaching the yaml --
deployment_yaml.yaml
Here's the service that provides a public IP and fwds requests to the container ports 3100 and 3000
service.yaml
But when I connect to the service I get the following error --
Copy code
Error connecting to the GrowthBook API
I've even tried setting the host header to "Host: localhost" but to no avail
anyone know how to resolve this?

I see you're wanting to run the API on port 2100
Copy code
name: API_HOST
          value: <http://localhost:2100>
but that error shows the API host is set to 3100
can you open up localhost:2100? does it work if you visit it directly (if its working, it will show you a json obj)

checking now
the other thing that happens is
the API service stops working as soon as I load the site on port 2000

Copy code
-- % kubectl get pods -o wide                                   
NAME                           READY   STATUS    RESTARTS   AGE   IP          NODE                                                  NOMINATED NODE   READINESS GATES

Forwarding from 127.0.0.1:2100 -> 3100

I see this output and then after I refresh a few times
it stops working

the api host in the url is not consistent with the api_host variable the API is getting from the env variable - but this should never cause it to just stop working...

is there a better way to deploy to a k8s cluster?

sounds like you're very close, just the env variables aren't quite right - but can you use a Helm chart? https://github.com/growthbook/growthbook/pull/103/
