Databases

Postgres and Redis-compatible databases from official images, each with its own volume and generated credentials.

Supported engines

The Redis option runs Valkey, the BSD-licensed fork of Redis. It speaks the same protocol, so existing Redis clients work unchanged.

Connecting from an app

Databases publish variables that apps in the same project can reference:

DATABASE_URL=${{db.DATABASE_URL}}
REDIS_URL=${{cache.REDIS_URL}}

References resolve on every deploy, so rotating a password only needs a redeploy of the apps that use it.

Private by default

Dockyrd never publishes a database port. Databases are reachable only from services in the same project. Docker-published ports bypass ufw, so this default matters.
