Looks good but have they finally added TLS between Promtail and Loki? If so, is there a good documentation about it?

In some environments where I need to put promtail on external probes I was surprised to learn that you couldn't establish TLS between promtail and a loki server. I had to instead setup nginx proxies between the external probe and our internal cluster. This was a year or so ago.

Original issue about it was: https://github.com/grafana/loki/issues/475 (looking at last comments, seems like people are still having issues to easily set it up)

I recently set up Loki and added NGINX to handle TLS. I noticed Loki's poor native TLS capabilities and thought "Huh, that's annoying".

Luckily, NGINX's configuration isn't too difficult to set up and I got started by working off of the example docker-compose stack referenced in https://grafana.com/docs/loki/latest/getting-started/

It seems that authentication and network security is out of scope for Loki, which is fine so long as that's stated explicitly and documentation is clear about what you need to use along with Loki to get those features. I agree that the documentation could use some serious work. The information is there, just not as clear as it could be.
