Loading system logs into Loki

Our first step is to download and launch the Loki pipeline services with Docker Compose. We will use a sample docker-compose.yml file, which can be downloaded from the Loki GitHub repository (found at https://github.com/grafana/loki). By now, the docker-compose.yml file should seem familiar and pretty straightforward. In our initial deployment, we will set up three services: loki, promtail, and grafana. Let's have a quick look at the configuration for each service:
