How to run Transmission on a seedbox you own

Download torrents — the simplest client here, few knobs. Cresdock runs it on a server you own, from a catalogue, with no Docker and no reverse proxy to configure.

What Cresdock does for you with Transmission

• Its configuration is written before the container ever starts — including the web address it lives at, so Transmission generates correct links from the first page load instead of half-working behind a prefix.

• Reached through your panel login. There is no second password to invent for Transmission and no port to open on your firewall.

• Your Downloads and Media folders are already mounted, and they are the SAME folders your other apps see — so files land where the rest of your setup expects them, with no path mapping to work out.

• Because it can fill a disk, it is metered against your storage limit and paused if you run out — instead of silently filling the server.

• Sonarr, Radarr, Lidarr and Prowlarr are introduced to Transmission for you the moment both are installed, in either order — new episodes, films and albums are handed over to fetch, and filed away once they arrive.

• If you also install cross-seed, it adds the matches it finds straight to Transmission, without fetching any of it a second time.

• autobrr is the exception: its filters live in its own store, behind an account you create inside it, so that one link is yours to make.

Why run Transmission yourself

Running a client on your own always-on server means it keeps working when your laptop is shut, on a connection that isn't your home one.

What kind of server Transmission needs

Disk is the constraint, not power. A torrent client is happy on a small server; what it needs is somewhere to put the files and a connection that isn't throttled. Cresdock meters what you use and pauses downloading rather than letting a disk fill, so a small server fails safely instead of breaking.

Cresdock itself is undemanding — it runs on a small rented server, an old desktop or a mini PC, on Ubuntu or Debian. Everything it installs shares that machine, so the honest question is not "will this app run" but "how much am I going to put on here in total".

Where to run Transmission

Transmission runs wherever Cresdock runs, and the choice is about the machine, not the app:

• At home, on hardware you already own. A mini PC, an old desktop or a NAS that can run Debian. Cresdock works behind a home router with no port forwarding and no domain, so Transmission is reachable on your own network first and from outside only if you choose.
• On a rented server. A small VPS is enough for most apps and is the usual answer when Transmission should be reachable from anywhere. The setup guide covers the specs and the one-command install.
• Through a provider that runs Cresdock. Hosting companies deploy Cresdock workspaces for their customers, so Transmission can come with a server you rent rather than one you set up — ask your provider, or see how providers offer it.

Installing Transmission

1. Put Cresdock on a server

   One line on any Ubuntu or Debian machine — a rented VPS, a spare PC, a home server. It sets itself up.

2. Pick Transmission from the catalogue

   Click Install. The panel pulls the image, writes the configuration, gets a certificate and starts it.

3. Open it from your dashboard

   Its address and any login details are on its card. Start, stop, update, roll back or remove it from the same place, any time.

What this replaces

Doing it by hand means writing something like this, then keeping it working:

services:
  transmission:
    image: lscr.io/linuxserver/transmission:4.1.3-r0-ls355
    restart: unless-stopped
    ports:
      - "9091:9091"
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - ./transmission/config:/config
      - ./downloads:/downloads
      - ./media:/media

And that is the easy half. Still to do:

• Install a reverse proxy and write a server block for it

• Get a TLS certificate and set up automatic renewal

• Create the folders above with the right ownership, or it will not start

• Decide what happens when the disk fills, because nothing here will stop it

• Repeat all of it for the next app, and again on every server rebuild

On Cresdock, Transmission is one click and none of the above exists.
