Promtail Loki Grafana Using Docker Compose | Grafana Loki Demo

In this video we are going to learn about how to setup Promtail Loki Grafana Using Docker Compose. In previous videos on Grafana Loki, we have seen setting up Grafana Loki Promtail using CentOs and normal docker containers. In this Loki tutorial we learn about loki and promtail config files and how to write the docker compose file for running Promtail, Loki and Grafana services.

is there a way to do alerts with logs like this? e.g. if any log has the "ERROR" words it will fire up an alert and notify.

Could the same configuration be done in Windows? And how do you send logs to loki? Thanks a lot!

Hi there, thanks for the video. Been using Grafana for a while and got Promtail/Loki working in Docker tonight. With this current config though, help me wrap my head around WHERE these logs are coming from. Are these logs coming from the Loki or the Promtail container....or is the the Docker host? If I wanted to monitor other logs in other containers on the same Docker network what are we looking at adding?

Thanks so much!

Followed your video and yaml files, but cannot figure out why I am getting this error. I even made the /usr/local/promtailloki permissions recursive 777. On docker-compose up I get this and loki does not come up.
