docker network create app-net

docker run -d --name=transmission --restart=always --network=app-net \
    -p 8080:9091 -p 8081:51413 -p 8081:51413/udp \
    -e USER=admin \
    -e PASS=pwd123 \
    -v /opt/transmission/config:/config \
    -v /opt/transmission/downloads:/downloads \
    -v /opt/transmission/watch:/watch \
    linuxserver/transmission

Note: don't forget to change password for web interface.

Testing Transmission

Open a web browser and go to http://<IP_ADDRESS>:9091, where <IP_ADDRESS> is the IP address of the system. Log in to the web interface with the admin username and password.

docker rm --force transmission

Remove Transmission image:

docker rmi linuxserver/transmission

You can also remove Transmission data:

sudo rm -rf /opt/transmission

If a user-defined bridge network was created, you can delete it as follows:

docker network rm app-net
