We have a cloud instance of GB and we want to spin up a self-hosted proxy. Since it will be created in a

k8s

cluster, the other microservices will communicate with it internally. We can (additionally) expose its endpoint externally. My question is the following: What should be the value of

GROWTHBOOK_API_HOST

env var? I assume this should be set to the one that the GB cloud (managed instance) will try to reach it or the one that the other microservices will try to contact?
