Redirect to HTTPS on custom entrypoint

Hi everyone,

I am trying to serve a http service on port 8080. but It only works when I go to https://localhost:8080 but doesn't work when I go to http://localhost:8080. What I want is to forward the http traffic that comes in to 8080 to https protocol.
So that when I visit http://localhost:8080, It would still get a response.

Here's a minimal code of what I'm trying to do -

services:
  traefik:
    command:
      - "--providers.docker"
      - "--entrypoints.customweb.address=:8080"
      - "--log.level=DEBUG"
    depends_on:
      - whoami
    image: traefik:v2.11
    ports:
      - mode: host
        published: 8080
        target: 8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  whoami:
    image: traefik/whoami
    labels:
      - traefik.http.routers.whoami.entrypoints=customweb
      - traefik.http.routers.whoami.rule=Host(`localhost`)
      - traefik.http.routers.whoami.tls=true
      - traefik.http.routers.whoami.service=whoami
      - traefik.http.services.whoami.loadbalancer.server.port=80

That should simply work with RedirectScheme midleware (doc).

Redirect middleware seem not to work.

It's redirecting https://localhost:8080 to https://localhost:443

services:
  traefik:
    command:
      - --providers.docker
      - --entrypoints.customweb.address=:8080
      - --log.level=DEBUG
    depends_on:
      - whoami
    image: traefik:v2.11
    ports:
      - mode: host
        published: 8080
        target: 8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  whoami:
    image: traefik/whoami
    labels:
      - traefik.http.routers.whoami.entrypoints=customweb
      - traefik.http.routers.whoami.rule=Host(`localhost`)
      - traefik.http.routers.whoami.tls=true
      - traefik.http.routers.whoami.service=whoami
      - traefik.http.services.whoami.loadbalancer.server.port=80
      - traefik.http.middlewares.redirect-mw.redirectscheme.scheme=https
      - traefik.http.middlewares.redirect-mw.redirectscheme.permanent=true
      - traefik.http.routers.whoami.middlewares=redirect-mw

The documentation is your friend:

port
The port option defines the port of the new URL.

I added the port but that didn't work either.

I still get -

curl -Lk http://localhost:8080
404 page not found

services:
  traefik:
    command:
      - --providers.docker
      - --entrypoints.customweb.address=:8080
      - --log.level=DEBUG
    depends_on:
      - whoami
    image: traefik:v2.11
    ports:
      - mode: host
        published: 8080
        target: 8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
  whoami:
    image: traefik/whoami
    labels:
      - traefik.http.routers.whoami.entrypoints=customweb
      - traefik.http.routers.whoami.rule=Host(`localhost`)
      - traefik.http.routers.whoami.tls=true
      - traefik.http.routers.whoami.service=whoami
      - traefik.http.services.whoami.loadbalancer.server.port=80
      - traefik.http.middlewares.redirect-mw.redirectscheme.scheme=https
      - traefik.http.middlewares.redirect-mw.redirectscheme.permanent=true
      - traefik.http.middlewares.redirect-mw.redirectscheme.port=8080
      - traefik.http.routers.whoami.middlewares=redirect-mw

Ok, maybe it doesn't work anymore. It works with http when you remove tls. I know that people where complaining that you could do a http connection even though tls was enabled.

Here we go (doc):

When a TLS section is specified, it instructs Traefik that the current router is dedicated to HTTPS requests only (and that the router should ignore HTTP (non TLS) requests).

Yes, I also reached similar conclusion, maybe it doesn't work.

I tried a lot and finally ended up in forum as last resort! :slight_smile:

Thank you!
