A fast time series database with SQL, a web console, the PostgreSQL wire protocol on 8812 and InfluxDB line protocol ingestion on 9009. The console and the PostgreSQL port share one generated password. Only the console is offered a domain. This page describes the Levelrail template for QuestDB (Database Tools). It deploys the services below as one Docker Compose app on your own server. Project site: https://questdb.com/docs/. Recommended memory: about 1024 MiB.

Security and requirements

Level: Standard. What this template needs:
  • Passwords and keys are generated at deploy time (questdb): QDB_HTTP_PASSWORD, QDB_PG_PASSWORD.
  • Stores data in named volumes (questdb): questdb_data.
What Levelrail adds around it:
  • Automatic HTTPS and an ingress shield in front of every domain.
  • Secrets are generated, stored encrypted and masked in logs and the UI.
  • Named volumes can be backed up and restored.
  • Deploys are gated on the health check before traffic switches.
  • One-step rollback to the previous revision.
  • Exposure report shows what is reachable from outside.
  • Host firewall rules managed for published ports.
