Simple SSL redirect in Træfik with Docker

Often the goal is just to make the server redirect from HTTP to HTTPS, meaning from www.mydomain.com to www.mydomain.com.

Using Docker with docker-compose it is possible to change Træfik's behavior through the so called "labels". To make Træfik redirect from HTTP to HTTPS it is enough to set the following label:

"traefik.frontend.headers.SSLRedirect": true

At the same time

"traefik.default.protocol": "http"

must not be set.
