Transmission

Transmission is designed for easy, powerful use.

When application is installed, a container will be launched with root privileges. This is required in order to apply the correct permissions to the Transmission directories. Afterward, the Transmission container will run as a non-root user (Default: 568).

For additional configuration via environment variables, see Container's source env var list.
