Traefik 3 and FREE Wildcard Certificates with Docker

[@pedrohcunha6857]

I can't fathom how easy you made this process, which I have been unable to do with other tutorials. You're doing great work Tim!

Spectacular video. I appreciate that you have a corroborating document site for the stuff you reference in here, as well. I also appreciate how meticulous you are in the details and troubleshooting. Thanks a ton, Tim.

compare to the last video of Traefik , i had 0 issue love how you explain things very easy and in simple way 😍

[@oildiggerlwd]

Greatly appreciate the little detail explanations. I’d done the wild card certs before on my home lab, but this is filling in several little knowledge holes in my mind. Excellent content

Sweet, I used most of your last Traefik video (never got external access working, but internal worked just fine, and that's all I needed, really)

[@osaether]

My point is: I haven't noticed any changes. Do I need to reconfigure anything?

[@rx2gamingofficial]

Thank you so much for the updated tutorial. Not sure if you got my email about the last one not working but this one works now. Tip for anyone with the certs not loading: just force recreate the container and it should load. I think this happens because the first time the certs are getting created but not read, and the second time it can actually read them.

This video gave me the info I needed to finish my migration to Traefik. Thank you Techno Tim!

[@ave4687]

HAHAHA you gotta be kidding me. I spent the 2 last weeks with your previous video and other resources trying to set up Traefik and the rest of my homelab. I literally closed the YT video minutes ago as I was finally able to make everything work. Before going to bed, I decided to check a video from my feed to cool down and what do I see if its not this taunting title XD. Anyway, I'll watch it later as it may allow me to enhance my fresh configuration. Thanks for that 😊

Perfect timing! I've been intersted in Traefik and leaving NPM. Thank you Tim!

[@SenorHamburgler]

Why may I ask? I use NPM and it's so seamless and easy

[@lidbergtech]

@@SenorHamburgler I like to tinker and spin up new things quite often, NPM is great for ease of use. Traefik is just more powerful and diverse, especially with docker, kubernetes and promox. Nothing wrong with NPM, just having the knowledge of how traffic work is good on the cv as well. :)

[@BrantScalan]

Would you consider adding another video to a Traefik series where you integration Authentik with Traefik ? I know you did a video about Authelia sometime back but it would great to see an update with Authentik and an outpost with Traefik. Also I love this video especially from the self hosted side and not having to have private records in an external DNS. But is your Traefik container reachable from the outside or do we just need Let's encrypt to find a valid domain for DNS auth and then it will issue the wildcard cert to the traefik container. Love you content

[@espressomatic]

This might be the definitive guide for Traefik 3

[@panthonyy]

I rarely watch 40 mins long videos thru the end. Awesome vidéo tutorial! Been searching a bit online how to do this. Can't wait to set that up :)

[@TechnoTim]

Awesome, thank you! That's a huge compliment!

[@panthonyy]

I'm a web dev and let's say that I watch, read and write a whole lot of tutorials/documents. The quality level of your tutorials is up there man, I learn more than what you teach from your videos. You do deserve the compliment.

[@redsoldier123]

Took me a while to figure out but, note to self: using .yaml extension will break things.... switched it back to yml and it worked just like the video. Great tutorial!

[@carstenr.1682]

Great video, Tim! Proxmox has its own ACME integration, so I personally prefer that way (because traefik is running as a VM on my Proxmox, so I want to prevent a race condition when the VM is down, Proxmox is not available through Traefik But for anything else - Traefik is great

[@xDrShadowx]

I had the same thought about Proxmox. Any TLS termination with the right certificates should be made directly on Proxmox anyway. If you want to be agressive, this should be the same for most services as well (internal certificates with local CA between internal containers to reverse proxy // letsencrypt certificates on the reverse proxy to the rest of the world)

[@ManelRodero]

​@@xDrShadowxcan you explain a little more this solution for Proxmox? If It uses its own ACME for talking to Let's Encrypt, then we need to create its CNAME on CF instead of Pihole. Right?

[@MrIanPreston]

Appreciate the update. Another great video that explains what is needed to be done, how to do it and why it has to be done. Your videos are so much more than simple 'follow me' instructions and really do help to provide some understanding. Thank you.

[@singh.karanbir]

[@pieter7416]

Interesting tutorial! I think it'll really help some people in setting Traefik up, which at first use, can be a bit daunting. However, Traefik now officially supports HTTP3, so I think you should open both ports 443 tcp as well as udp in your compose file. Make sure to update your firewall settings / port forwards as well. - 80:80 - 443:443/tcp - 443:443/udp Also, one of the strengths of Traefik is that after adding the "config" volume once, you shouldn't have to run "docker compose up" when changing config.yaml. Lastly, I personally like to also use logs, so choose to add this volume as well: "- /opt/traefik/logs:/logs:rw" and try to name compose files "compose.yml", as it saves a few keystrokes.

[@TechnoTim]

Thanks for the great tips! I will also add this to the docs!

[@denix0]

Thanks for this, very informative! At 11:07 you say "we need to create a docker network called proxy", but I couldn't see where it's done... Anything special about it? Which driver does it use?

[@PopularWebz]

A few notes: You are using both cli config and YAML config on the Traefik container. Move that all into the YAML file. Also you shouldn't be specifying your email for cloudflare, you should be using a scoped taken instead. Also at this point you should be enabling strictSNI and a minimum TLS version of 1.2

Hey, This is super interesting and your acknowledgement and sort of rant about the docker secret feature, Awesome ! I have a question though: Say you are using tailscale currently, which doesn't support subdomains ? The 2 level subdomain thingy that you did, using cloudflare. Would that even work ? Could I use a WireGuard server that I deploy on DigitalOcean

[@mathurin_hv]

Really helpful ! Thank you ! Could you make a video to explain how to convert that configuration to a docker swarm ?

[@scottmielke4071]

Do you use traefik for externally accessible services? How do you typically separate those? Different docker hosts? How do you do the networking since you don't need to modify the internal DNS?

[@Genesis8934]

12:16 traefik defaults to yml, but can be overridden with a command line option. --configFile

[@RadTechDad]

This is great and all.... but only for internal services. If you want to have a public-facing service, you can't do a second-level wildcard cert going through cloudflare without paying for a cert from them.

[@rzvendramini]

Great video! But afer watching it, I applied the ideas to configure Caddy. Traefik is excellent, but the configuration file is a bit complex and lengthy.

[@dorvinion]

Thanks for the local only explanation. Every one of these I've seen before expects you to want to directly expose things externally. Yes I want to access from outside, but only after I've connected to WG/OVPN One question, can this be done without the local subdomain? Would you just need to remove the . local subdomain from the examples provided?

[@shawn2296]

Would you consider doing a video on getting this setup and running?

[@snopz]

This is awesome! You managed to explain Traefik so clearly in just one video-amazing work! I do have a quick question: How can I access my services from outside my home network? I understand that I need to expose only port 443 on my router, but the issue is that the setup uses the local DNS server to resolve the domains to Traefik. Because of this, it doesn’t work outside my network. Thanks a ton for your hard work and for making Traefik so much easier to understand!

[@TechnoTim]

@@snopz thank you! you need to set up external DNS to point to your IP and then port forward to traefik.

[@snopz]

​@@TechnoTimI set up an AAAA record in Cloudflare DNS pointing to my public IPv6 address since my router only allows port forwarding over IPv6, not IPv4. Honestly, it's better this way-no need for dynamic DNS since I can assign a static IPv6 address that’s unlikely to change.

[@sonalita_]

will there be a similar update for the Kubernetes version?

[@CyrrelSneer]

Why don't you let out the pihole part and create the DNS records within cloudflare?

[@michaelgleason4791]

Because he's doing this locally? He's only using cloudflare for the DNS challenge. He was pretty clear about that.

[@chits2391]

Hi Tim! Great tutorial! I've followed the steps and wondering if you could give some insights as to why I can't open the traefik dashboard after setting local dns using pihole. I can get pings from the url, and when I use curl, it says Moved Permanently. Hoping you could see this. Thanks Tim!

[@Invaderjason123]

I'm confused with all the .local references. If you have a domain name and Cloudflare, why wouldn't you just put a wildcard CNAME on your Cloudflare DNS settings? This is the the part that confused me so much doing the records on pi-hole.

[@michaelgleason4791]

Well, because he's doing this for LOCAL services only, not ones exposed to the Internet.

[@MKBUHDD]

If you are familiar with cloudflare, could you please tell me: - Can I buy a domain from any provider and register it (transfer) it for cloudflare and manage it as if i bought it from them? so I can use their tunnel service and other features? - Do you think cloudflare tunnel is better than reverse proxy to expose your home server to public?

[@BerliOfficial]

@@MKBUHDD I only can answer your first question. You can buy a domain nearly anywhere, you just have to set the nameserver in your dns settings (where your domain is) to the cloudflare nameservers shown in your account. After that you have the full experience of dns settings at cloudflare as far as I know.

[@MKBUHDD]

@@BerliOfficial Thanks for the info, then I will look for a cheap domain. 👍🏻

[@BreetaiZentradi]

I would love to see a video covering the pros and cons of Traefik 3 vs caddy-proxy-manager vs nginx proxy manager. I thought Caddy was going to be the bees knees so I went that route for my homeserver. Pros: the label sections in the docker-compose.yml is self contained and no need for open ports on the host, and you can use any caddy directives you want. Cons: You have to have the the docker-compose.yml files have a default external network. For work I have had to use nginx proxy manager (npm). Pros: All done in a gui, all the configs are centralized in npm. It is easy to setup certs for containers available on the local network by using a duckdns with an IP set to your private netowork and you do not have to have an external network setup. Cons: You have to have open ports to all the services on the host.

Failed one more time :) , I can't understand what I am missing. Thank you for your efforts Tim :)

[@stevendonaldson1216]

I've been through these YT follow-along errors. It's literally the main job of network engineers to solve the problems you're going to run into. Time to strap in, find the problem or just restart from clean install. Both work out in the end.

[@xneakersvault1556]

Any recommendations to troubleshoot when the cert is from traefik and not from let's encrypt.

[@zer0r00t]

I don't think the DNS part tells the CA to check those specific DNS servers. That would be a huge security risk. It simply tells traefik to use those DNS to verify that the TXT records are indeed visible globally before saying the CA to proceed with the next step (ACME protocol). What public DNS the CA queries from is not publicly documented
