Transmission

Transmission docker container

What is Transmission?

Transmission is a BitTorrent client which features a simple interface on top of a cross-platform back-end.

How to use this image

This Transmission container was built to automatically download a level1 host filter (can be used with dperson/openvpn).

sudo docker run -it --cap-add=NET_ADMIN --device /dev/net/tun --name vpn \
            --dns 8.8.4.4 --dns 8.8.8.8 --restart=always \
            -d dperson/openvpn-client ||
sudo docker run -it --name bit --net=container:vpn \
            -d dperson/transmission
sudo docker run -it --name web -p 80:80 -p 443:443 --link vpn:bit \
            -d dperson/nginx -w "http://bit:9091/transmission;/transmission"

NOTE: The default username/password are admin/admin. See TRUSER and TRPASSWD below, for how to change them.

NOTE2: To connect to the transmission container, point your browser to the actual <hostname_or_IP_address> of the system running docker with a URI as below:

https://<hostname_or_IP_address>/transmission/web/

NOTE3: To open the peer connection port add the following to the docker run command:

-p 51413:51413 -p 51413:51413/udp

Hosting a Transmission instance

sudo docker run -it --name transmission -p 9091:9091 -d dperson/transmission

OR set local storage (see Complex configuration below):

sudo docker run -it --name transmission -p 9091:9091 \
            -v /path/to/directory:/var/lib/transmission-daemon \
            -d dperson/transmission

NOTE: The configuration is in /var/lib/transmission-daemon/info, downloads are in /var/lib/transmission-daemon/downloads, and partial downloads are in /var/lib/transmission-daemon/incomplete.

Configuration

sudo docker run -it --rm dperson/transmission -h

Usage: transmission.sh [-opt] [command]
Options (fields in '[]' are optional, '<>' are required):
    -h          This help
    -n          No auth config; don't configure authentication at runtime
    -t ""       Configure timezone
                possible arg: "[timezone]" - zoneinfo timezone for container

The 'command' (if provided and valid) will be run instead of transmission

ENVIRONMENT VARIABLES

TRUSER - Set the username for transmission auth (default 'admin')
TRPASSWD - Set the password for transmission auth (default 'admin')
TZ - Configure the zoneinfo timezone, IE EST5EDT
USERID - Set the UID for the app user
GROUPID - Set the GID for the app user

Other environment variables beginning with TR_ will edit the configuration file accordingly:

TR_MAX_PEERS_GLOBAL=400 will translate to "max-peers-global": 400,

Examples

Any of the commands can be run at creation with docker run or later with docker exec -it transmission transmission.sh (as of version 1.3 of docker).

Setting the Timezone

sudo docker run -it --name transmission -e TZ=EST5EDT \
            -d dperson/transmission

Complex configuration

If you wish to adapt the default configuration, use something like the following to copy it from a running container:

sudo docker cp transmission:/var/lib/transmission-daemon /some/path

You can use the modified configuration with:

sudo docker run -it --name transmission -p 9091:9091 \
            -v /some/path:/var/lib/transmission-daemon -d dperson/transmission
