What is the project about?
The project, docker-otel-lgtm, provides a pre-configured OpenTelemetry backend packaged as a Docker image. It's designed for development, demonstration, and testing purposes.
What problem does it solve?
It simplifies setting up an observability backend for OpenTelemetry, allowing developers to quickly get started with collecting and visualizing telemetry data (logs, metrics, and traces) without complex configuration. It also allows easy data forwarding to external vendors.
What are the features of the project?
- Includes pre-configured components: OpenTelemetry Collector, Prometheus, Tempo, Loki, and Grafana.
- Easy to run with provided scripts (
run-lgtm.sh,run-lgtm). - Optional logging for troubleshooting individual components.
- Ability to forward data to external vendors (like Grafana Cloud) using
OTEL_EXPORTER_OTLP_ENDPOINTandOTEL_EXPORTER_OTLP_HEADERS. - Option to persist data across container restarts by mounting a volume to
/data. - Kubernetes deployment support.
- Works out-of-the-box with OpenTelemetry's default settings.
- Includes example applications in various languages (Java, Go, Python, .NET) to demonstrate telemetry data generation.
