OpenTelemetry stack on Docker

Docker environment for running an OpenTelemetry stack locally using:

• Prometheus for metrics;
• Mimir as Prometheus long-term storage;
• Loki for logs;
• Tempo for traces;
• Grafana Agent as telemetry collector;
• Grafana for visualization;
• MinIO as storage for Mimir, Loki, Tempo.

The goal is to provide the simplest and lightest setup possible for running these components together. This means no authentication, no HA configuration, no load-balancer, no TLS.

Setup

Clone the repository with:

$ git clone git@github.com:nunchistudio/docker-opentelemetry.git

Then, start the Docker environment:

$ cd ./docker-opentelemetry
$ docker compose up -d

At this point you should have all containers running (truncated for better visibility):

$ docker ps

IMAGE                    PORTS
grafana/agent:latest     0.0.0.0:7020-7021->7020-7021/tcp
grafana/grafana:latest   0.0.0.0:3000->3000/tcp

grafana/tempo:latest     0.0.0.0:3200-3201->3200-3201/tcp, 0.0.0.0:50397->7946/tcp
grafana/loki:latest      0.0.0.0:3100->3100/tcp, 0.0.0.0:50398->7946/tcp
minio/minio:latest       0.0.0.0:9000-9001->9000-9001/tcp

You can access the Grafana dashboard at http://localhost:3000. Datasources are already configured to work with Mimir, Loki, and Tempo.

OpenTelemetry collector endpoint is exposed at localhost:7021.
