Directus

Convert any SQL database into a powerful API and CMS platform

Redis

The internal hostname of the Redis server on Railway's private network. This is automatically set by Railway and uses the `.railway.internal` domain for secure, private communication.

An alias for `REDIS_PASSWORD`. This references the auto-generated Redis password.

The port number on which the Redis server listens. Standard Redis port is 6379.

The username for connecting to Redis. Railway typically sets this to `default` if Redis ACLs (Access Control Lists) are enabled.

The password for authenticating with the Redis server. This is automatically generated by Railway using a secure random generator.

Connection string for connecting to redis externally

Connection string for connecting to redis using the private network

Postgres

Public URL to connect to Postgres database, used by the Data panel.

Location where the database will be initialized

Default database created when image is started.

directus/directus

The email address for the initial admin user account. This user has full access to the Directus admin panel.

The password for the initial admin user account. Change this immediately after first login.

Automatically clears cache when data is modified. Ensures users always see the latest data after updates.

Enables or disables caching in Directus. When enabled, Directus caches frequently accessed data to improve performance.

Specifies which caching backend to use. Set to `redis` for Redis, or `memory` for in-memory (not recommended for production).

The database client library to use. Set to `pg` for PostgreSQL.

Complete PostgreSQL connection string. Alternative to setting individual DB_* variables. Uses Railway's private network for secure, free communication.

Maximum number of database connections in the connection pool. Higher values allow more concurrent database operations but use more resources.

[Don't change] Enables Railway's private networking feature for Alpine-based containers. Allows services to communicate over Railway's internal network.

Port number that Directus listens on. Used in PRIVATE_URL template strings. Directus defaults to 8055 if not set.

Internal URL used by Directus for server-to-server communication. Important for multi-instance deployments and internal API calls.

The public-facing URL where your Directus instance is accessible. Used to generate absolute URLs for API responses, file URLs, and email links.

[Don't change] User ID that Railway runs the container as. Set to `0` (root) for Railway's Alpine-based containers.

Complete Redis connection URL. Uses Railway's private network for secure, free communication.

A secure random string (32+ characters) used by Directus for encrypting sensitive data, session tokens, and API keys. This must be unique and kept secret.

Directory path where local storage files are saved. Only needed if `STORAGE_LOCATIONS=local`.

Comma-separated list of storage locations to use. Set to `local` for local storage, or `s3` for S3-compatible storage.

Storage backend for coordinating actions across multiple Directus instances. Set to `redis` for multi-instance deployments, or `memory` for single-instance.

Enables WebSocket support for real-time features (live updates, collaboration). Requires Redis.
