A MongoDB compatible database that stores documents in PostgreSQL. Runs FerretDB with a bundled PostgreSQL that has the DocumentDB extension, a persistent volume and a generated password. It is not published on the host, so reach it from other services in this project at ferretdb:27017. This page describes the Levelrail template for FerretDB (Database Tools). It deploys the services below as one Docker Compose app on your own server. Project site: https://docs.ferretdb.io/. Recommended memory: about 512 MiB.

Passwords and keys marked as generated are created for you when the app is deployed and stored as secrets. Values are not shown here.

Security and requirements

Level: Standard. What this template needs:
  • Passwords and keys are generated at deploy time (ferretdb, postgres): FERRETDB_POSTGRESQL_URL, POSTGRES_PASSWORD.
  • No health check, so a deploy is judged by the process starting (ferretdb).
  • Stores data in named volumes (postgres): pgdata.
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.
