Deploy and Host HashiCorp Vault on Railway

HashiCorp Vault is a secrets management tool that provides secure storage, dynamic credentials, encryption as a service, and fine-grained access control for sensitive data. This template deploys a production-ready Vault server on Railway with sensible defaults and an easy path to scale.

About Hosting HashiCorp Vault

Vault runs as a single service that exposes an HTTP API and an optional web UI for managing secrets, policies, and authentication methods. It can operate in development mode with in-memory storage for quick testing, or in production mode with persistent file-based storage. Railway makes it simple to deploy Vault without managing servers, while enabling vertical scaling and persistent storage for your secrets engine.

Common Use Cases

• Centralized secrets management for applications and infrastructure
• Dynamic credential generation for databases, cloud providers, and services
• Encryption as a service for sensitive data at rest and in transit
• Access control and audit logging for secret operations

Dependencies for HashiCorp Vault Hosting

The Railway template includes all required dependencies: the Vault runtime and configuration. No additional databases or services are required.

Implementation Details

Architecture Components

This template deploys one service:

• Vault Server: secrets engine exposing the HTTP API and optional web UI

Server Configuration

Vault is configured via environment variables at deploy time:

• ENV: Set to dev for development mode (in-memory storage) or production for persistent file storage
• PORT: HTTP listener port (default: 8200)
• UI_ENABLED: Enable or disable the Vault web UI
• STORAGE_PATH: File-based storage path for production mode
• DEFAULT_LEASE_TTL: Default lease duration for dynamic secrets
• MAX_LEASE_TTL: Maximum allowed lease duration
• DEV_ROOT_TOKEN_ID: Root token for development mode

Development Mode

Running in development mode (ENV=dev) uses in-memory storage. Redeploying, upgrading or restarting the Vault will erase all data.

To avoid data loss, use medusa to export your secrets before upgrading and re-import them afterward.

License Information

HashiCorp Vault is source-available under the Business Source License (BSL 1.1). See the Vault repository for full license details.
