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.
