Hello Selfhosted peeps!

So I just got Traefik v3 setup inside my docker environment, and successfully got SSL certs for my services hosted within docker. However, I have an external device hosting PiHole and Wireguard-UI. I am looking to use the docker instance of Traefik v3 to obtain SSL certs for the internal use only for PiHole and Wireguard-UI.

I am still new to Traefik, and have no idea if this is possible, or how I would go about doing this.

Any tips, suggestions, links to documentation; I am all ears.

      Would the file provider configs live on the Traefik server, or would they need to be on the external service. Reading through this, and looking at the example configuration files doesn’t really seem to point that out. Sorry for the noob questions.

      Trying to understand this, but the way the documentation is written is different than I am used to.

      Thank you!

        No worries for the question. It’s not terribly intuitive.

        The configs live on the Traefik server. In my static traefik.yml config I have the following providers section, which adds the file provider in addition to the docker provider which you likely already have:

        providers:
  docker:
    endpoint: "unix:///var/run/docker.sock"
    exposedByDefault: false
  file:
    directory: /config
    watch: true

        And in the /config folder mapped into the Traefik container I have several files for services external to docker. You can combine them or keep them separate since the watch: true setting tells it to read in all files (and it’s near instant when you create them, no need to restart Traefik).

        Here is my homeassistant.yml in that folder (I have a separate VM running HASS outside of Docker/Traefik):

        http:
  routers:
    homeassistant-rtr:
      entryPoints:
      - https
      service: homeassistant-svc
      rule: "Host(`home.example.com`)"
      tls:
        certResolver: examplecom-dns

  services:
    homeassistant-svc:
      loadBalancer:
        servers:
          - url: "http://hass1.internal.local:8123"

        Hope this helps!

          so in my traefik.yml file I have cloudflare set as my certresolver as follows:

          certificatesResolvers:
  cloudflare:
    acme:
      email: email@example.com
      storage: acme.json
      caServer: https://acme-v02.api.letsencrypt.org/directory # prod (default)
      # caServer: https://acme-staging-v02.api.letsencrypt.org/directory # staging
      dnsChallenge:
        provider: cloudflare
        #disablePropagationCheck: true # uncomment this if you have issues pulling certificates through cloudflare, By setting this flag to true disables the need to wait for the propagation of the TXT record to all aut>
        #delayBeforeCheck: 60s # uncomment along with disablePropagationCheck if needed to ensure the TXT record is ready before verification is attempted 
        resolvers:
          - "1.1.1.1:53"
          - "1.0.0.1:53"

          And I had to get the secret mounted via the docker-compose file.

          So where you have:

          tls:

                  certResolver: examplecom-dns

          Do I have to redefine all of the same information I did in my Traefik yml but in this separate config.yml?

          (I did set it up in my traefik.yml and docker-compose.yml to mount and use this config, which I had commented out for later use.

          Thank you so much for the help!

          Edit:

          Essentially I am trying to get my PiHole which is hosted on another pi setup with an SSL cert for local use only:

          So in looking at your config I tried using:

          http:
  routers:
    pihole-rtr:
      entryPoints:
      - https
      service: pihole-rtr
      rule: "Host(`ph.local.domain.com`)"
      tls:
        certResolver: cloudflare

  services:
    pihole-svc:
      loadBalancer:
        servers:
          - url: "http://<ip>/admin"

          However when doing this error logs returned:

          
2024-07-08T15:04:27-04:00 ERR error="the service \"pihole-rtr@file\" does not exist" entryPointName=https routerName=pihole-rtr@file
2024-07-08T15:04:28-04:00 ERR error="the service \"pihole-rtr@file\" does not exist" entryPointName=https routerName=pihole-rtr@file

          I am doing something very wrong… And feel a little lost.

            I think you’re close.

            You need to change service: pihole-rtr to service: pihole-svc.

            Do I have to redefine all of the same information I did in my Traefik yml but in this separate config.yml?

            No, you just need to reference it like you have. Define once, reference many.

              I hate to report back, but something isn’t quite working for pihole behind Traefik.

              running “docker logs traefik” returns no error, and yet no certificate was presented to my pihole.

              Not sure what else I might be missing or that I might have wrong.

              I will give this a shot! Thank you for the help. I will report back, in hopes that between your knowledge and my fumbles that someone else too can learn from this!
