We used traefik for hosting multiple web sites on a single VPS with docker and docker compose and as ingress controller for kubernetes. We used Let's Encrypt option, and SSL termination feature. For Ingress Controller we found traefik better supported and more stable than more wide-spread nginx-based ingress controller.

We are using Traefik as a reverse proxy to our backend.

The software is great, a little confusing at first but it is useful in configuration and debugging purposes.

I have been using Traefik for several years.

We use Traefik in both Dev and Production environments, allowing us to prevent unattended bugs between the different environments.
