+# TimescaleDB
+
+TimescaleDB is deployed as a PostgreSQL-compatible database on the internal `timescaledb:5432` service.
+
+Connection values:
+
+- Host: `timescaledb`
+- Port: `5432`
+- Database: `${postgres_db}`
+- Username: `${postgres_user}`
+- Password: generated by Dokploy
+
+The template creates the TimescaleDB extension during first initialization. PostgreSQL initialization variables only apply when the data volume is empty.
+
+Telemetry is disabled by default with `TIMESCALEDB_TELEMETRY=off`. The image runs `timescaledb-tune` automatically on first initialization and reads Docker cgroup limits when available.
