Redirect http to https

Traefik Traefik v2 (latest)
1

Hi,

I've been struggling with creating the redirect from http to https. At this moment in access log I get
"GET / HTTP/1.1" 404 19 "-" "-" 99 "-" "-" 0ms when I visit http, when I visit https i get
"GET / HTTP/2.0" 200 93343 "-" "-" 137 "app-fe@docker" "http://172.25.0.3:3000" 134ms

I've tried following numerous guides for creating the middleware and router for this, I've tried to establish secure dashboard access, but no luck.

This is my current compose file. I would really need some pointers on what I'm doing wrong.

You can only have one .rule= per Traefik router (with the same name).

Usually apps don’t like to be places under a PathPrefix, they expect to be in root (/). They will redirect, link and load images and scripts with absolute paths. To make it work, they would need some kind of base-path setting to adjust. That’s why usage of sub-domains is best practice.

Some images (declare to) expose multiple ports in Dockerfile, choose which one to use.

Don’t expose the ports of services/containers other that Traefik, as that might circumvent security middlewares and might disable TLS. This is not necessary when using a Docker network, Traefik will reach the ports internally.

Check and compare to simple Traefik example. To make it clean when using Traefik v2, add .entrypoints=websecure to each router.
