Install Transmission

  • Host network

Run the following command to create a container for Transmission that uses host network:

docker run -d --name=transmission --restart=always --network=host \
    -e USER=admin \
    -e PASS=pwd123 \
    -v /opt/transmission/config:/config \
    -v /opt/transmission/downloads:/downloads \
    -v /opt/transmission/watch:/watch \
  • User-defined bridge network

User-defined bridge network can be used for listening on different port. By default, Transmission service is listening for TCP and UDP connections on port 51413. Web interface is available on port 9091. Ports can be changed with -p option.

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 \

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

    Thanks for that.
    What if we are deploying the container on Ubuntu VM running on ESXi host and we want to access the files downloaded, here it will be located?
    Is there any how to map a NFS folder to downloads the file into there automatically from transmission?
    Thanks, cheers

      In the Docker command -v /opt/transmission/downloads:/downloads, the -v option specifies a volume mapping between the host machine and the Docker container. The /opt/transmission/downloads is the directory path on the host machine. This is the location where you want to store the downloaded files.
      Docker provides the capability to mount directories shared over the NFS. Please read Docker documentation regarding this.
