How One Developer Uses Traefik and Docker to Automate Reverse Proxy in a Homelab

A developer shared their homelab setup using Traefik as a reverse proxy to manage multiple Docker-based services such as Pi-hole, Vaultwarden, and custom applications. Rather than manually editing Nginx configs and juggling port numbers, Traefik automatically discovers Docker containers and routes traffic using container labels. The setup handles HTTPS certificates automatically via Let's Encrypt, eliminating the need for manual SSL configuration. Traefik is configured as the sole internet-facing service, while all other containers communicate internally through a dedicated Docker network. A key design choice is disabling automatic container exposure by default, ensuring only explicitly labeled services are made publicly accessible.
