Deploy and Host Celery Flower (w/ Auth) on Railway

Celery Flower is a real-time web-based monitor for Celery task queues. It provides visibility into task progress, worker status, and queue metrics. This template includes caddy-zero-trust for Basic Auth protection, ensuring your monitoring dashboard is not publicly accessible.

About Hosting Celery Flower (w/ Auth)

This deployment consists of two services: Flower and caddy-zero-trust. Flower connects to your Redis broker and exposes a dashboard on port 5555 via Railway's private network. caddy-zero-trust sits in front as the public entry point, requiring authentication before proxying requests to Flower. Railway handles TLS termination, while the internal communication between services stays on the private network.

Common Use Cases

Monitor Celery worker health and task throughput in production
Debug failed tasks and inspect task arguments/results
Track queue lengths and worker resource usage
