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

[@chrschra]

I've also learned way more than I was expecting

[@espressomatic]

This might be the definitive guide for Traefik 3

[@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 😊

Anonymous window in browser is always the good way for testing changes.

[@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.

[@Ellwood420]

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)

[@johnny4ever5]

**knows he can create/edit file in one step but prefers two steps** Bravo good sir! So satisfying...

[@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.

[@Breeegz]

It's a shame that KZbin only allows for me to like this video once. This was a big upgrade from your last "SSL Everywhere" video. Thanks for taking us on your journey.

[@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?

[@lidbergtech]

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. :)

[@philbudgen5090]

Great informative, educational video. This video helped me so much to get traefik working. Very detailed vid and additional documentation provided. Keep up the great work. Many thanks.

[@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.

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.

[@wojtek-33]

Thanks for this. Real easy to follow and worked on my first attempt. I am testing this as a replacement to Nginx Proxy Manager. No nice text based config, but NPM is 100x easier and faster to setup and add sites. Good to have a back up though!

[@Crusaderzpl]

Thanks Tim! finally managed to get Traefik fully working in my homelab, great tutorial as always

[@romayojr]

this is perfect timing i just rewatched your old traefik video yesterday cuz i’m having some weird connection issues with my traefik server that i setup last year that has been working great for me. i might re-spin up my server with traefik 3 this weekend to see if resolves my issues. thanks tim!

how does this video have only 3.4k views? I watched it like 6 times start to finish alone.

[@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!

[@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.

[@1gold4]

I am finally tackling the project of my homelab again and I am so grateful to see a new video for Traefik. These types of videos are such a huge help.

[@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

[@drbyte2009]

Tim, you make super great video's, in one word PERFECT!!

[@nippurtech572]

Bro.... This tutorial was AMAZING!

[@Skyverb]

Everything went well for me until around the 27 minute mark. I followed along well until there; keep getting can't connect to that domain error. Double and triple checked the steps like crazy. Dunno what I'm doing wrong.

[@shawn2296]

sigh why why i will probably add 200k views i love that you did i will buy a new cluster set up again man i learned a sh!t ton from your videos and even landed a network gig cuz of how much i dabbled thanks alot

[@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. 👍🏻

[@Glitch_860]

anotther great tutorial. you mention difference in Docker Swarm. I am running a docker swarm in my homelab so would love to be pointed to documentation for that config. Also can I setup 2 certs in Traefik?

[@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.

[@raymondvanderwerf]

wow....thx man! I will set this up for sure 🔥🔥🔥

[@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?

[@mathurin_hv]

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

[@LegionInfanterie]

Thank you Tim, this is what I looking for this is best guide

[@Dirizabl]

Great video, thank you Tim! Would you recommend switching to Traefik v3 if already have v2 setup working?

[@jerealityjr]

Great Video, any plans for a video on how to securely expose to the internet?

[@paulobaronceli]

I have created some automation scripts based on your tutorial to make the entire process (almost) 1-step. Stupid KZbin keeps deleting my comments even though there's no links or no anything at all harmful, and it's 100% related to your video.

[@Robert65536]

[@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.

[@marinuspretorius8230]

I followed this tutorial but I just keep on getting TRAEFIK DEFAULT CERT. I have everything the same except pihole. I use adguard and I have configure my domains in there. It resolve but does not get the lets encrypt cert

[@Synoap]

yes the same here, but Im using pi-hole. Anyone else? @TechnoTim can help us?

[@Mstaaravin]

A magnific tutorial, thanks!

[@nicoladellino8124]

Very useful and nice video bro, THX.

[@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?

[@meetthesandvich211]

I had to remove the basic auth and .env because the traefik container would not move past the login prompt for the dashboard even though I put the user name and password in correctly, but I would love to see video on how to get the dashboard working with Authentik. 👍

[@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

[@codeman99-dev]

11:54 Unless I'm mistaken, changing permissions on the host is generally not recommended. If I remember correctly, this is forcing your container user to have the UID as the host user. Better options: 1. Use a Dockerfile and change the permissions during copy: `COPY --chmod=0600 acme.json /acme.json` 2. Use a docker volume (not a bind mount) so that permissions are handled by the container only. Use option 1 if persistence doesn't matter. Use option 2 if persistence does matter.

[@RocketLR]

Uugh my traefik is causing so much problems when i try to deploy my react app.. so many different header settings that cause weird behavior with no freaking error output 😵

[@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!

[@TudorRusu89]

Just neat and on point! Congrats! Been following your videos for a while. A couple of questions: 1. How about exposing multiple ports on Traefik? 2. How about exposing multiple external services? 3. Can you do a more deep insight tutorial about internal DNS setup? All the best!

Whats the biggest new thing here, compared to v2? How bad of an idea would it be to just upgrade? At first glance i haven't noticed that at least the important settings changed that much

[@W31rdG]

Thanks for the great tutorial Tim. I'd been struggling to get either Proxmox or Portainer to work properly behind Traefik, but I got it working by following your video. Question. How do you get something like AdGuard Home or Pi-Hole to work with Traefik? AGH requires a location for the SSL certificates, so how do you get it to read the acme.json file? Also, how do you get AGH to work with DoT and DoH?

[@shrinivaskopparamramanath3930]

Is there a guide for creating a setup with some applications you want to expose to the public and some you want local only, and having wildcard certificates created for it all through traefik?

[@nemac23]

36:47 The "secured" middleware chain doesn't seem to be applied to any of the routers. Assuming this is an editing mistake?

[@demorez5]

i was considering moving to traefik for ages, but everytime I look into that it seems so overwhelming its not worth the effort. SWAG works for me like a breeze, does everything I want from it and the setup is like 10% of this.

[@briankeane5589]

Great video, but doesn't seem to work for me.. Once I get to the DNS part and setup the record with cloudflare.. it only ever points back to the TrueNas login page and I don't know what to do..

[@tjoptjop09]

Hi Tim, thanks for sharing this amazing video. I only need more help setting up multiple routers in the config file you showed us. can you explain how I can add more external servers outside docker to my config. like my firewall interface, other homeserver, printers etc

[@michaelgleason4791]

I don't understand at all why you use a .local. Instead of forwarding 80 and 443 to 80 and 443, I forward them to 81 and 444. Then traefik is set up to know that those are external services, and it's just a couple extra labels. If traefik gets requests on 80 and 443, it knows that those are local. And I setup a wildcard for my domain internally so I don't have to manually add each one.

[@cjchico]

I could set it up in the 'external' way like you did for Proxmox, and I'm happy to do that, just wondering if there is maybe a cleaner way to do that (or even a second Traefik instance for the second docker environment..)
