Infrastructure
Infrastructure overview
How the Lok Panchang stack is run: Docker, Meta/WhatsApp, AWS, Caddy, and Ngrok
The application runs on a mix of Docker Compose (all app services), Meta WhatsApp Business API (webhooks and messaging), and AWS (EC2 for hosting; optional S3 for log backups). Caddy provides the public entrypoint and TLS in production; Ngrok is used in development to expose the webhook locally.
