I was able to build a cloudformation config for Fargate communicating gRPC without the need for an HTTP proxy. It does health checks on gRPC as well. currently, only API is exposed to the outside - port

. Should not be too difficult within reason to add mappings for 8080 and 9090, as well. Happy to share my findings, if this might help someone, as a reference for their ECS clusters. In my experience, often, it is easier to throw containers on Fargate and not having to worry about managing a full K8s cluster.
