docker-otel-lgtm

Grafana's docker-otel-lgtm is a single Docker image that bundles the whole LGTM stack plus an OpenTelemetry Collector. LGTM stands for Loki (logs), Grafana (dashboards), Tempo (traces), and Mimir/Prometheus (metrics), with Pyroscope (continuous profiling) thrown in. Apache 2.0 licensed.

The point of the image is one command: `docker pull grafana/otel-lgtm && ./run-lgtm.sh`. Port 3000 is Grafana, everything else is pre-wired underneath. You point your app's OpenTelemetry exporter at the collector and you have a working observability backend in under a minute. Perfect for trying OTel pipelines, demoing a feature, or developing instrumentation locally.

Solo developers and small teams use this for local dev and CI test environments. For production, Grafana explicitly tells you to run the components separately or pay for Grafana Cloud. There is no HA, no multi-tenancy, no persistence guarantees in the bundled image.

The catch is the production warning is not optional. The image is built for convenience, not durability. Use it to learn OpenTelemetry, build instrumentation, or demo dashboards. When you go to production, plan to split Loki, Mimir, Tempo, and Grafana into separate deployments with their own storage backends. That is a different project, not a Docker run command.
