[kube-prometheus-stack] Thanos Prometheus sidecar

[jholowaty]

Describe the bug a clear and concise description of what the bug is.

I have a doubt with the configuration of the thanos sidecar.

thanosService: enabled: true annotations: {} labels: {}

## Denotes if this Service desires to route external traffic to node-local or cluster-wide endpoints
##
externalTrafficPolicy: Cluster

## Service type
##
type: ClusterIP

## gRPC port config
portName: grpc
port: 10901
targetPort: "grpc"

## HTTP port config (for metrics)
httpPortName: http
httpPort: 10902
targetHttpPort: "http"

## ClusterIP to assign
# Default is to make this a headless service ("None")
clusterIP: "None"

## Port to expose on each node, if service type is NodePort
##
nodePort: 30901
httpNodePort: 30902

The theory says that if thanosService is True then 1 more container is up inside the Prometheus deploy but in my case, thats not happend!!

pod/prometheus-prometheus-kube-prometheus-prometheus-0 2/2 Running 0 4m21s

So when I enter the thanos query website, I don't see any metrics.

If i try the bitnami kube-prometheus, when prometheus pod starts, i see 3 containers and one of them is the thanos sidecar, so then in the thanos querier web, i saw the metrics.

What i'm doing wrong with the kube-prometheus-stack that i can't initialize the sidecar in prometheus pod?

Thanks a lot!!!!
