Deploy and Host KrakenD on Railway

About Hosting KrakenD

KrakenD Community Edition is a high-performance stateless API gateway. This template deploys stable version 3.0.2 with a working private echo backend so the gateway path can be tested immediately and then replaced with your own APIs.

Common Use Cases

Route a public API to private Railway services
Aggregate and transform backend responses
Apply gateway rate limits and transport policies
Maintain API gateway configuration in Git

Dependencies for KrakenD Hosting

Deployment Dependencies

Public KrakenD gateway
Private Caddy echo backend used as a replaceable example
No database or persistent volume

Implementation Details

Railway HTTPS routes to KrakenD on port 8080. BACKEND_URL references the private echo service on port 8081. The adapter renders a runtime configuration, validates it with krakend check, and starts only when the full file is valid. /api/demo proves end-to-end private routing; /__health supplies readiness.

The included rate limits and demo route are a starter, not a complete production security policy. Fork the repository and update gateway/krakend.template.json for your real APIs.

Why Deploy KrakenD on Railway?

Railway provides managed HTTPS, private DNS, health checks, Git-based configuration deployment, and repeatable gateway rollouts without exposing backend services publicly.
