Traefik and local serving with TLS

An unrelated thing I really like about Traefik is its flexible service autodiscovery. At a previous job, I set it up running in Docker Compose, with a specific network it listened for; all other services, in local dev mode, would join that network and had labels attached that let Traefik know about them and route to them the same way a real API gateway would, which meant it was possible to orchestrate multiple local services in a production-style setup and not have them all fighting over the same port for HTTP, etc.
