We have Loki and Tempo running in a Kubernetes cluster and Grafana on a separate one. We want to use that Grafana to access the Tempo traces as well as Loki logs. We are also using Istio as a service mesh. Loki has a gateway for basic authentication that you can use during setup. As Loki and Tempo have similarities I wonder if Tempo also has a Gateway that can be used for that purpose. I haven’t been able to find much in the documentation.
