Hey, Christian, at 20:50 you wonder why service name doesn't allow numbers and dashes, but earlier, at about 13:15 you define a Regex, that only allows letters: subhost:[a-z]+ May be it will help if you also allow dashes and numbers there: subhost:[a-z0-9-]+
I can confirm that is what you need to add. You can also set it to "subhost:[a-zA-Z0-9-]+" to allow lower case, uppercase, numbers, and a dashes. Your problem is traefik thinking the server does not exist based on the name.
how the hell do you do it! this is the third time now I have wanted to install something, given up, and then within 48 hours you post the exact video I need!
Thank you again for your hard work. One more question. How did you manage to get a valid certificate on the 2nd level subdomain with cloudflare? Did you use universal edge ssl certificate, or you have ordered an advanced plan? I use the univrersal one, but my traefik falls back to the traefik default ssl certificate above the 1st level subdomain (with error). Thank you!
@@christianlempa I also don't see a way around this as the only way I can access the teleport instance is locally. cloudflare does not support a sub-sub-domain with a universal cert. this basically makes teleport useless.
@@dbishop9085only if you proxy your traffic inside cloudflare for sub sub domains, let's encrypt can generate multiple certificates without an issue for as deep as you like.
Great content (as always) :) Could you show how to configure traefik, when you want to add that container in 2 networks (DMZ, and backend), and open ports only for the DMZ network? Thank you for your work!
Thanks! Let me think about that, that would need some more time for preparation, but an interesting topic for sure. Maybe I would include this in a topic about DMZ networks in general and how to separate your home network with a firewall.
Thanks for sharing, Christian. I'm creating my homelab, and it's helping a lot. One thing that I couldn't understand is how you're connecting through Teleport from outside your network. Do you have a fixed IP from your internet provider? I saw the other Teleport video you shared using the cloud solution, and it made sense as you are running an agent inside your local server. But how about this local Teleport? Can I access it from outside? How? Cheers mate!
As always, great video Christian! I have an interesting use case: I want to secure an HTTP API using Teleport, which some developers will access using curl or Postman. I'm not necessarily asking for a video on this, but I wonder how the authentication would work if there is no browser involved. This seems like a very legit use case; I haven't really researched it yet, but was watching this, and it came to mind. EDIT: I wonder if I can authenticate in a browser and use the tokens from its local storage on the CLI with curl or in Postman
Hi Christian, awesome videos. I will try tonight on my OCI Ampere VM. I will report on the output. Truly, I was in doubt about using a separate Standard.E2.1.Micro VM just for the teleport (like a gateway machine). Would you happen to have any opinion on that? Remembering we can have both on the free tier (the beefier Ampere and 2 micro VMs). Beautiful shirt by the way - " This is the way"

With Traefik and Teleport Docker Networks (Frontend in this video) - Is it a good idea to have these containers seperate from containers such as Game Servers. Is it also safe to say that any Web containers like 'NGINX' would need to be a member of this 'Frontend' network in order for Traefik to be able to communicate - Or could web servers also have their own docker network?
Awesome video as usual ! but the issue with the name in the app_service of teleport come from the traefik routers configuration! indeed the regex in the host only match a-z :) 🎉
Thanks for the video, traefik is really great. But I now run so many containers that my Synology with 2gb ram does not get along. Can you explain how to set reasonable memory limits in a home lab in such cases?
hmm i'm wondering how i can setup the automatic certificates resolver with stratoDNS since it isn't supported by traefik yet. any idea cause i can't really find a decent info page about this... Strato supports DynDNS, any idea how i can get that connected to traefik? fyi, i'm pretty new to traefik, but you could already tell i assume
Nice Tutorial, could you make a video of the docker socket proxy from tecnativa? It is proxy for the docker socket to limit access to certain permissions to the docker api and would enhance security for the usage of traefik and other containers which need direct access to the docker socket.
Hello, I followed the tutorial to try to secure my setup. Everything works except that I am unable to start a virtual machine or access the shell. It return the error 501
Hello Christian, forgive me for going off topic but you had briefly showcased an open source mind mapping app in a past vdieo that looks like hand witten (possibly) like a chalkboard, in one of your past videos but I cannot find it because it was not the main topic of that video. I would be truly grateful if you would share the name with me please? - Dennis
Hey there! I am getting this error: Access Denied Unable to serve application requests. Please try again. If the issue persists, verify if the Application Services are connected to Teleport. I followed every step you did and it doesn't work when I click on my proxmox.... Any ideas?
Hello, Christian, first of all thank you for your great videos. Trying it out for myself is really fun. But somehow I don't understand something here. The plan is to make my Portainer UI and the Traefik Dashboard only accessible via Teleport. In other words, the labels for Traefik are not set here, because otherwise it would also be publicly accessible. But with a pure teleport access, I fail. So here I am still missing a little, maybe someone can give me a hint where the thinking mistake is.
For traetik to be aware of containers creation need to be connected to the docker socket of on that server. Never try this between two separate server but maybe through tcp. On server 1, you expose the socket via tcp (docker-socket-proxy ?) and from server 2 you access this tcp port. BIG CONCERN : Exposing docker socket can lead to big security hole, especially through Internet
@@christianlempa I have an issue, I am following your video but when I do, docker compose up, the containers shows me this error: zone ***/IN: NS 'ns.***' has no address records (A or AAAA)
Can maybe someone give me any advice on my plans. I want to deploy a Cloud Server with Traefik and Teleport, this server will also host other Docker apps. Now my plan is to use Teleport to make these other Apps Accessible. Is this the right use case? Sure there are other ways like traefik as the reverse proxy and then use Authelia etc. for Authentication for the apps. This would work but I don’t want to use Authelia,Authentic etc. because these projects don’t seam to be maintained anymore, also I would like to get some of the Teleport features. And in the future I just can add more cloud or even local server to use teleport.
if you have ssl certs stored in acme.json ... will it still hit the rate limit on lets encrypt if you down and up the containers 50 times ? i believe the limit is 50 per week

Unfortunately doesn´t work in combination with existing internal traefik and authelia and the here showed teleport config...

I would also be interested to know if this is possible, but I think not.

I'd simply deploy Traefik on both servers. I'm running like 5 or 6 Traefik instances in my entire network :D
I would like some of these services to the public internet. Do you create another traefik as a forwarding proxy to the backend proxies?
where is the link to the config?
I just started to test teleport and i thought it is a reverse proxy by itself, so why do i need an additional reverse proxy?
14:10 ahh because you run all services and teleport on the same docker instance
Does not run on separate test docker, too! Does anybody get this content running?!?
