Global redirect www to non-www with HTTPS redirection

Traefik Traefik v2

Good day,
I have applied a global HTTP -> HTTPS redirection using this this approach and it works fine. Additionally, I would like to add global www -> non-www redirection, which gets applied to any route.

This my static configuration:

# static configuration
[entryPoints]
   [entryPoints.web]
      address = ":80"

   [entryPoints.web-secure]
      address = ":443"

I have added additional router, middleware and noop service, so my configuration looks like this:

# dynamic configuration
[http.routers]
   [http.routers.redirect-to-https]
      entryPoints = ["web"]
      middlewares = ["https-redirect"]
      rule = "HostRegexp(`{host:.+}`)"
      service = "noop"

   [http.routers.redirect-to-nonwww]
      entryPoints = ["web-secure"]
      middlewares = ["nonwww-redirect"]
      rule = "HostRegexp(`{host:(www.+)}`)"
      service = "noop2"

[http.middlewares]
   [http.middlewares.https-redirect.redirectScheme]
      scheme = "https"
      permanent = true

   [http.middlewares.nonwww-redirect.redirectRegex]
      regex = "^https://www.(.*)"
      replacement = "https://$1"
      permanent = true

[http.services]
  [http.services.noop.loadBalancer]
    [[http.services.noop.loadBalancer.servers]]
      url = "http://192.168.0.1"

   [http.services.noop2.loadBalancer]
    [[http.services.noop2.loadBalancer.servers]]
      url = "http://192.168.0.2"

If I try this configuration, the the www -> non-www redirection does not work. However, if I try to apply the redirect middleware directly within a Docker service:

whoami:
    image: containous/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.whoami.entrypoints=web-secure"
      - "traefik.http.routers.whoami.rule=HostRegexp(`{host:(www.)?example.com}`)"
      - "traefik.http.routers.whoami.tls.certResolver=web"
      - "traefik.http.routers.whoami.middlewares=nonwww-redirect@file"

it does work. But still, this approach is not global.
First thing that occurred to me is the fact that the redirect-to-nonwww router gets a lower priority than any other application router because its rule is simply shorter. I tried setting the priority:

 [http.routers.redirect-to-nonwww]
      entryPoints = ["web-secure"]
      middlewares = ["nonwww-redirect"]
      rule = "HostRegexp(`{host:(www.+)}`)"
      service = "noop2"
      priority = 100

but with no success.
Is there a chance to apply both HTTPS redirection and www -> non-www redirection globally?
Thank you!

Hey @Dandry,
any news on this. Do you have a working global redirect you could share?

3

@Dan42 hi, no.
I still plug in the redirect middleware explicitly to every service I want the redirect for. Still hoping for someone from the dev team shedding some light here.

There are already quite a few threads on this. Here is one of them: A global http -> https redirection?

@ldez Is there a github issue for that, since you said, that you are aware / want to improve this?

@ldez Thank you for this, someone came up with this workaround:

        # Global http to https redirect
        traefik.http.routers.http-catchall.rule: "hostregexp(`{host:.+}`)"
        traefik.http.routers.http-catchall.entrypoints: web
        traefik.http.routers.http-catchall.middlewares: redirect-to-https

It seems to work, any downsides of this solution?

It's my solution :smile: Global http to https redirect in v2

And an awesome solution it was :grin:!

On a side note, I noticed you created a posting on GItHub regarding (or someone did) and I didn't notice the CLI version on there. Should it be on there as well to make sure if they use it they post up both version, does it not make a difference or did I just completely miss it (highly likely)?

Thanks again.

To answer to original question, a global approach can be:

🐋 With the Docker provider: 
version: '3.7'

services:
  traefik:
    image: traefik:v2.1.3
    command:
      - --entrypoints.web.address=:80

      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --log.level=INFO

      traefik.http.routers.whoami.rule: Host(`whoami.localhost`)
      traefik.http.routers.whoami.entrypoints: websecure

  address = ":443"

[providers.file]
  directory = "/dyn/"

  rule = "HostRegexp(`{host:(www\\.)?.+}`)"
  entryPoints = ["web"]
  middlewares = ["wwwtohttps"]
  service = "noop"

# middleware: http(s)://(www.) to  https://
[http.middlewares.wwwtohttps.redirectregex]

  permanent = true

# NOOP service
[http.services.noop]
  [[http.services.noop.loadBalancer.servers]]
    url = "http://192.168.0.1:666"

Results:

http://whoami.localhost -> https://whoami.localhost
http://www.whoami.localhost -> https://whoami.localhost
https://www.whoami.localhost -> https://whoami.localhost
🐋 FYI another way (less global) to do that: 
version: '3.7'

services:
  traefik:
    image: traefik:v2.1.3
    command:
      - --entrypoints.web.address=:80
      - --entrypoints.websecure.address=:443
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --log.level=INFO
    ports:
      - 80:80
      - 443:443
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
    labels:
      traefik.enable: true

      # middleware: http:// to  https://
      traefik.http.middlewares.tohttps.redirectscheme.scheme: https
      traefik.http.middlewares.tohttps.redirectscheme.permanent: true

      # middleware: https://www. to  https://
      traefik.http.middlewares.trim_www.redirectregex.regex: ^https://www\.(.+)
      traefik.http.middlewares.trim_www.redirectregex.replacement: https://$${1}
      traefik.http.middlewares.trim_www.redirectregex.permanent: true

  whoami:
    image: containous/whoami
    labels:
      traefik.enable: true

      traefik.http.routers.whoami.rule: Host(`whoami.localhost`, `www.whoami.localhost`)
      traefik.http.routers.whoami.entrypoints: websecure
      traefik.http.routers.whoami.middlewares: trim_www
      traefik.http.routers.whoami.tls: true

Note: the redirections are made by routers, the routers are a part of the dynamic configuration, so a CLI flags version is not possible because flags handle the static configuration.

Hi Idez,

This is what I'm looking for as I have spent countless hours trying to figure out how to do the www to http redirect to no avail... EXCEPT... I can't get it to work. I'm close but having Let's Encrypt issues (at least that's what I think my issue is).

What's happening:

Not sure why when I enter https://www... it doesn't work. I'm assuming it's trying to check the certificate before it does a redirect (URL remains at https://www.traefik-whoami.creativesandbox.dev). Same result in both Safari and Firefox though warnings are worded differently.

I tried adding and extra rule to the whoami service so that it read "Host(traefik-whoami.creativesandbox.dev) || Host(https://www.traefik-whoami.creativesandbox.dev)" but that didn't make any difference... and now I'm out of ideas.

Maybe I'm searching for the wrong things but all my searches for www to non-www have not helped me (until you came along with this).

Thanks for all the work so far, here's hoping you can help with this last little bit. Current code below:

You need to make sure that the cert matches all the domains https connection can come to. I do not see you configuring any sans so that could be the reason.

12

I'll be honest, I'm struggling to wrap my head around this. So far I have done everything use CLI (labels) but I only see examples for SAN using yaml or toml files? Does this mean I need to create now or those? And/or do I need to switch back to DNS challenge instead of TLS because I must say the DNS challenge was a pain in the proverbial as every time I created a service I had to wait for it to propagate (and remember too)?

13

CLI and labels is not the same. CLI refer to static configuration and labels refer to dynamic one, these are not to be mixed. I'm assuming you don't actually mean CLI, but labels.

The labels reference is here: https://docs.traefik.io/reference/dynamic-configuration/docker/ Search for tls.domains

14

Thanks. It took me ages to learn/wrap my head around SANs but managed to get it working with two additional lines per service.

traefik.http.routers.whoami.rule: "Host(`traefik-whoami.craighofman.art`)"
traefik.http.routers.whoami.tls.domains[0].main: traefik-whoami.craighofman.art
traefik.http.routers.whoami.tls.domains[0].sans: www.traefik-whoami.craighofman.art

Tried leaving out the main but that didn't work.

15

I experienced the same problem: https://www.domain.tld was not redirected to https://domain.tld. The other two global redirects worked.
In my case I could solve it with adding the wwwtohttps middleware to the whoami container as well:

services:
  whoami:
    image: containous/whoami
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.whoami.rule=Host(`domain.tld`, `www.domain.tld`)"
      - "traefik.http.routers.whoami.entrypoints=websecure"
      - "traefik.http.routers.whoami.tls.certresolver=httpchallenge"
      - "traefik.http.routers.whoami.middlewares=wwwtohttps@docker"
    networks:
      - traefik

networks:
  traefik:
    external:
      name: traefik_default

But this is probably not a recommended solution. I will have to get into SANs as well :sweat_smile:

Hi idez,
I have updated my .toml file but only https redirection is working and the remaining ones are not working.
My toml file:

[entryPoints]
  [entryPoints.web]
    address= ":80"
  [entryPoints.web-secure]
    address = ":443"
  [entryPoints.dashboard]
    address = ":8080"

[api]
dashboard=true
[certificatesResolvers.default.acme]
    email = "cbtu44@gmail.com"
    storage = "acme.json"
    [certificatesResolvers.default.acme.dnsChallenge]
        provider = "gcloud"
        delayBeforeCheck = 0
[providers.docker]
  exposedByDefault = false
  endpoint = "unix:///var/run/docker.sock"
  watch = "true"
  network = "proxy"

[traefik.http.routers.http-catchall]
  rule = "HostRegexp(`{host:(www\\.)?.+}`)"
  entryPoints = ["web"]
  middlewares = ["wwwtohttps"]

# Global redirection: https (www.) to https
[traefik.http.routers.wwwsecure-catchall]
  rule = "HostRegexp(`{host:(www\\.).+}`)"
  entryPoints = ["websecure"]
  middlewares = ["wwwtohttps"]
  [traefik.http.routers.wwwsecure-catchall.tls]

# middleware: http(s)://(www.) to  https://
[traefik.http.middlewares.wwwtohttps.redirectregex]
  regex = "^https?://(?:www\\.)?(.+)"
  replacement = "https://${1}"
  permanent = true
17

in the v2, the dynamic configuration and the static configuration must be defined in separated files:

and like in the v1 the file provider must be enabled to use dynamic configuration from file.

@ldez have defined the dynamic config in docker-compose file.

@ldez can you post an example of yaml that would work in kubernetes. Mostly docker examples. Need kubernetes example
