Loki docker-compose

Loki log aggregation system with docker-compose.

Whith this project you can test out loki with :

• Cassandra as index db
• Minio as chunks db
• Promtail
• Prometheus and cadvisor
• Traefik reverse-proxy for ssl

We recommand to use helm chart or check out the doc for production use. This repository will kickstart a loki instance to check out capabilities and configurations tweaks.

Running

Copy .env.dist to .env and /config/loki-config.yaml.dist to /config/loki-config.yaml and edit the two files.

You need to set minio access_key and secret in /config/loki-config.yaml.

To get a fully running stack, run docker-service-traefik with this docker-compose.

1. Copy configurations files

   # Copy env.dist
   cp .env.dist .env && cp config/loki-config.yaml.dist config/loki-config.yaml
   # Edit .env with your editor
   vim .env config/loki-config.yaml

2. Check configuration

   docker-compose -f docker-compose.yml -f compose/cassandra.yml -f compose/minio.yml -f compose/prometheus.yaml -f compose/traefik.yml config

3. Run the stack

   docker-compose -f docker-compose.yml -f compose/cassandra.yml -f compose/minio.yml -f compose/prometheus.yaml -f compose/traefik.yml up -d

4. Access grafana
   1. Add sources :
      • loki : https://$LOKI_DOMAIN with header X-Scope-OrgI: loki-internal.
      • prometheus: http://prometheus:9090
   2. Go to explorer and have fun !
