We use Traefik as the web server.

The reasons for choosing Traefik over Nginx are as follows:

  • Traefik built-in Let’s Encrypt and supports automatic renewal
  • Traefik automatically enables HTTP/2
  • Prometheus can be supported through simple Traefik configuration
  • cookiecutter django integrates Traefik's configuration by default

We switched to Traefik so we can use the REST API to dynamically configure subdomains and have the ability to redirect between multiple servers.

We still use nginx with a docker-compose to expose the traffic from our APIs and TCP microservices, but for managing routing to the internet Traefik does a much better job
