Not able to connect to weaviate instance from vectordbBench

Hi!

Here is how I do to connect to a minikube cluster with 3 nodes:

>> minikube start --nodes 3

>> kubectl get nodes
NAME           STATUS   ROLES           AGE     VERSION
minikube       Ready    control-plane   4m17s   v1.31.0
minikube-m02   Ready    <none>          4m7s    v1.31.0
minikube-m03   Ready    <none>          3m59s   v1.31.0

>> helm repo add weaviate https://weaviate.github.io/weaviate-helm

>> helm show values weaviate/weaviate > values.yaml

edit the values.yaml and enable the openai and set the replicas to 3

create the namespace:

>> kubectl create namespace weaviate

deploy the helm chart:

>> helm upgrade --install \
  "weaviate" \
  weaviate/weaviate \
  --namespace "weaviate" \
  --values ./values.yaml

watch your cluster starting, and wait all pods to be ready

>> kubectl -n weaviate get pods -w

those are the services we have:

>> kubectl -n weaviate get services
NAME                TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)           AGE
weaviate            LoadBalancer   10.107.66.168   <pending>     80:32443/TCP      106s
weaviate-grpc       LoadBalancer   10.97.59.100    <pending>     50051:30758/TCP   106s
weaviate-headless   ClusterIP      None            <none>        80/TCP            106s

we need to forward both http and grpc ports
note that the service for http is on port 80 and grpc 50051

kubectl port-forward service/weaviate 8080:80 -n weaviate
kubectl port-forward service/weaviate-grpc 50051:50051 -n weaviate

In order to test the GRPC endpoint, you can use grpcurl. Here is how to test without any auth or ssl

>> wget https://raw.githubusercontent.com/grpc/grpc/master/src/proto/grpc/health/v1/health.proto
>> grpcurl -plaintext -d '{"service": "Weaviate"}' -proto health.proto localhost:50051 grpc.health.v1.Health/Check
{
  "status": "SERVING"
}

Let me know if this helps!
