database

SKILL.md

Deploy PostgreSQL, Redis, MySQL, or MongoDB with pre-configured volumes, networking, and connection variables.

Supports four official database templates: PostgreSQL, Redis, MySQL, and MongoDB, each with persistent volumes and automatic connection variable setup

Always checks for existing databases before creating to avoid duplicates; queries environment config via GraphQL to detect running instances

Provides reference variables for connecting other services (e.g., ${{Postgres.DATABASE_URL}} for backends; public URLs available for frontend-to-database patterns)

Integrates with the environment skill to wire connection strings into dependent services after deployment

Database

Add official Railway database services. These are maintained templates with pre-configured volumes, networking, and connection variables.

For non-database templates, see the templates skill.
