cd to the cloned git repository, and build the docker container:
docker build -t YOUR-NAME/flexget .
Put your configuration in /srv/docker/flexget/, and then, to run the docker container, you can use the following command:
docker run -v /srv/docker/flexget:/config -p 5050:5050 YOUR-NAME/flexget:latest
The Web UI will be accessible on port 5050 of your host machine.
The Web UI is at a very early stage. It is not stable at all!
