I setup 2 Kubernetes clusters on Azure, Thanos Querier is in one cluster,
and a local prometheus+sidecar. I need to query the remote cluster Thanos
sidecar. I created ingress-nginx with support for grpc on remote cluster.
But the sidecar grpc failed in Thanos Querier so that Querier was not able
to discover the sidecar on remote cluster. I still had to use the ip and
port to discover the sidecar on remote clusters. Everytime the pod is
restarted, the ip changes and the connection is broken. Any advice?
apiVersion: extensions/v1beta1
kind: Ingress

namespace: espr-prometheus-nonprod

kubernetes.io/ingress.class: “nginx”
nginx.ingress.kubernetes.io/ssl-redirect: "false"
