What problem does this solve?

i Hope you are open to add the app to UmbrelOS Appstore it will be great addon

Thanks for the suggestion, and for the pointer to umbrelOS. I looked into what an Umbrel app would involve, and I've decided not to support it for now. Here's why.

Traefik Manager doesn't stand alone: it manages a Traefik instance, so an Umbrel app would have to ship Traefik with it. That's where it runs into umbrelOS itself. umbrelOS already runs its own reverse proxy, which serves the dashboard and puts every installed app behind its own login, and it owns ports 80 and 443. Traefik would have to sit beside that on alternate ports, and you'd need to forward 80 and 443 on your router to those ports before anything could be reached from outside, including Let's Encrypt's HTTP challenge.

The result would be two reverse proxies on one box, competing for the same job. Umbrel's proxy would still decide how its own apps are reached, while Traefik handled a separate set of routes on non-standard ports. That's confusing to set up and easy to get wrong, and it's not the experience Traefik Manager is built for. It would also mean running Traefik without access to the Docker socket, so the Docker provider would sit empty.

If you'd like a reverse proxy on Umbrel today, Nginx Proxy Manager is already in the Umbrel app store and is designed around these limits. And if you run Traefik on another machine, Traefik Manager works well there, installed with the tm installer or Docker Compose.

I'll keep this open as an idea in case umbrelOS changes how it handles ports or its proxy. Thanks again for raising it.

i know that NPM is already there, but I heavily invested in Traefik, especially after I discovered Traefik Manager, so I think i will stick with what I have until you decide to support it. Thank you again, keep the great work

Changed my mind on this one. You've clearly put real time into Traefik, so as long as you're OK with the setup it needs, I'm happy to support it.

It's up now as a community app store: https://github.com/chr0nzz/tm-UmbrelOS

In umbrelOS, open the App Store, the menu in the top right, Community App Stores, and paste that URL. There are two apps:

• Traefik Manager: Traefik Manager and its own Traefik, all on your Umbrel.
• Traefik Manager Agent: its own Traefik plus the agent, for when you already run Traefik Manager on another machine and want it to manage a Traefik on your Umbrel. Needs umbrelOS 2.0.

The setup that's on you, because umbrelOS keeps ports 80 and 443 for itself:

1. On your router, forward external port 80 to 42080 and 443 to 42443 on your Umbrel (43080 and 43443 for the agent app).
2. Point your domain's DNS at your public IP.
3. Route to other Umbrel apps by container name, for example http://immich_server_1:2283, not umbrel.local, which would put the Umbrel login in the way. Apps on host networking, like Home Assistant, are http://host.docker.internal:8123.

The README has the full details. You'd be the first to run it on a real Umbrel, so if anything doesn't behave, let me know here or on the Discord and I'll fix it.

our first issue when trying to install it any of the traefik manager or the agent

failed to install app
EEXIST: file already exists, mkdir '/proc/self/fd/155/traefik/traefik.yml'

[M0Pegasus]

i diagnosis the issue with the help of AI of course here is what i found

Installing Traefik Manager Agent on umbrelOS fails with:

EEXIST: file already exists, mkdir '/proc/self/fd/155/traefik/traefik.yml'

The app data directory ends up correctly populated (traefik/acme/, traefik/dynamic/, traefik/logs/, traefik/traefik.yml all present with sane content), so the file itself is created successfully — the error seems to come from a duplicate reference to the same host path.

In docker-compose.yml, the same source path is bind-mounted twice:

yaml

• type: bind
  source: ${APP_DATA_ROOT}/traefik/traefik.yml
  target: /app/traefik.yml
  read_only: false
  bind:
  create_host_path: false

• type: bind
  source: ${APP_DATA_ROOT}/traefik/traefik.yml
  target: /etc/traefik/traefik.yml
  read_only: true
  bind:
  create_host_path: false

My guess is umbrelOS's pre-install step walks each mount entry and tries to ensure the source path exists, succeeds on the first mount, then hits EEXIST on the second mount referencing the same file.
