Self-hosted infrastructure on Railway, deployed via GitOps.

Architecture

All services run on Railway in a single project. Each service has its own directory under services/. Existing services use railway.json; the messaging, eBay, gateway, identity services and private admin router use the mcp partial in .railway/railway.ts. See each service's directory for service-specific details.

Inter-service communication is over Railway's private network (*.railway.internal).

Native clients authenticate through Keycloak at mcp.janejeon.dev/auth and use /telegram, /whatsapp, /keycloak, or /ebay on the gateway. Permanent Jane username/password authentication serves the native clients. The Mac messaging launchers are disabled; preserve their data for rollback.

Deployment

All deploys go through git push. Existing services use railway.json watch patterns. The new MCP services are represented by the named mcp partial in .railway/railway.ts, which leaves the existing services outside its ownership.

Environment variables

Railway injects service variables at both build time (as Docker ARGs) and runtime (as ENV):

• Build-time ARGs: Used by mysql and hoyolab-auto for envsubst template rendering during docker build
• Runtime ENV: Used by ghost, uptime-kuma, mysql-backup at container start

Local Development

Prerequisites

• nvm — nvm use && npm install (installs git hooks)
• direnv — loads .envrc secrets automatically; service directories inherit RAILWAY_API_TOKEN from the root .envrc via source_up
• Gitleaks — brew install gitleaks (pre-commit secrets scan)
