Traefik DNS challenge with wildcard certificates | easy tutorial

Hey friends, in this video about the reverse proxy traefik, I'll show you how to configure traefik in the right way to use the dns challenge with cloudflare and issue ssl wildcard certificates with ease!
We just need some configuration for traefik, and some api keys for you dns provider (in my case cloudflare)
With this setup you are able to use wildcard certificates for you domain without opening ports on the host machine, where traefik is running. No http or https ports needed for that.
This can be extremely useful in homelab environments if you don't want or can't expose your ports to the internet, but still want to have certificates for you locally used domains.

How did i reserve proxy outside in docker

[@joanandestin4201]

Hi, How are you doing? My instance is on prem and I followed your example but it won't work for me. I removed the tag "# staging environment of LE, remove for real certs" but "Certificates": null. I am not sure why it is not working. Are we able to connect or can you help me?

[@techwithmarco]

Sounds like a timing issue when getting certificates. I'd recommend enabling debug logs of traefik and check what is in there! Drop me a mail! You can find it on my about the channel page.

The A record you make for dev. Is that public or private ip does it matter?

public ip
