A collection of docker-compose files designed to start cortex and loki locally

grafana-local

These docker-compose and associated config files can be used to start Grafana applications up easily. Simply navigate to the desired folder and run docker-compose up and you're ready to go.

There are two stacks at present. Each stack starts up the listed applications on the ports shown below.

• Cortex
  • Grafana: http://localhost:3000
  • Cortex: http://localhost:9009
  • Jaeger: http://localhost:16686
  • Prometheus: http://localhost:9090
• Loki
  • Grafana: http://localhost:3000
  • Loki: http://localhost:3100
  • Jaeger: http://localhost:16686
  • Promtail: http://localhost:9080

After running docker-compose up navigate to http://localhost:3000 and use Grafana to visualize the metrics/logs that are being stored. This is your primary way to see the data that Loki or Cortex are storing. Username/password is admin/admin. I'd recommend navigating to the Explore tab and checking out available metrics/log streams.

It's also fun to check Jaeger at http://localhost:16686 to see traces.

extra_hosts

You'll notice some commented out extra_hosts blocks in the docker-compose. I use these if I want to run Cortex or Loki on my machine in a debugger and connect the dependent services to it. In this scenario:

1. Comment out Cortex/Loki block so docker-compose doesn't start it.
2. Uncomment all extra_hosts blocks and add your machine's ip
3. Run Cortex/Loki locally on your host machine.
4. docker-compose up

One day I'll write a script to do this.
