Wild card certs with traefik - to many guides out there and none help

@dirtyharrywk welcome to the forums! Traefik and Docker with LetsEncrypt can definitely make you pull your hair out when getting started. Here are a couple of posts that I have written. I am not sure if you have looked at these as of yet. Let me know where you are running into issues. Normally it is always something small that trips many up with this.

If you want to go the Traefik route:

VIRTUALIZATIONHOWTO.COM "https://www.virtualizationhowto.com/2023/02/traefik-letsencrypt-certificates-configuration/"

If you want to try Nginx Proxy Manager (it is the easiest since it has a GUI):

VIRTUALIZATIONHOWTO.COM "https://www.virtualizationhowto.com/2023/10/setting-up-nginx-proxy-manager-on-docker-with-easy-letsencrypt-ssl/"

Hopefully we can work through the issues 👍 

@dirtyharrywk Also keep in mind, you will need to have a real registered domain out there that is reachable with DNS. What DNS provider are you using?

I'm confused on the step "Redirect to HTTPS".  Where does that go?  The traefik.yml file already has "middlewares" for HTTP.

traefik.yml:

providers:
  docker:
    exposedByDefault: false
  file:
    filename: /etc/traefik/dynamic.yml
  http:
    routers:
      dashboard:
        rule: Host(`traefik.MY_DOMAIN.com`)
        service: api@internal
        middlewares:
          - traefik-auth
        tls:
          certResolver: dns-cloudflare
    middlewares:
      traefik-auth:
        basicAuth:
          users:
            - "admin:admin"
certificatesResolvers:
  dns-cloudflare:
    acme:
      email: MY_EMAIL_ADDRESS
      storage: /letsencrypt/acme.json
      dnsChallenge:
        provider: cloudflare
        delayBeforeCheck: 0
      caServer:  https://acme-v02.api.letsencrypt.org/directory
