Uptrace
Uptrace is an open-source APM platform for traces, metrics, and logs using OpenTelemetry, with ClickHouse storage and PostgreSQL metadata. This template follows the official example/docker compose stack (Uptrace, ClickHouse, Postgres, Redis, OTel Collector, Vector, Grafana, Prometheus, Alertmanager, Mailpit). The Vector image uses timberio/vector:0.28.X-alpine to match that upstream example (legacy Docker Hub namespace); migrate to distroless/vector only when you intentionally diverge from upstream.
