I was using stable/prometheus-operator helm chart to deploy prometheus along with Thanos sidecar to AKS. I am working on deploying other Thanos components Querier and Store.

Querier and Store pods are up and running on AKS. However, I do not see Store from Querier interface. Any advice?

thanos-querier-69cdbd5bc6-dtj7c 1/1 Running 0 36m

thanos-store-0 1/1 Running 0 2s

Below is my config files for Querier and Store:
