PRE-REQUISTE:
./setup.sh

This will basically run:
docker network create frontend
docker network create backend

Create and bring up an Ubuntu instance with the following:
./create_user.sh john_doe 1001 2201 5901 your_secure_password
./connect_and_stream.sh

The ~ (home) directory is saved on the local disk in the ./data directory.

If you need to bring up a specific user:
docker-compose -f docker-compose.user_1001.yml build
docker-compose -f docker-compose.user_1001.yml up -d

OR MANUALLY:

Locally, type:
pulseaudio --load=module-native-protocol-tcp --exit-idle-time=-1 --daemon

export DISPLAY=:0
ssh -Y -C -p 2201 -L 4713:localhost:4713 -L 5000:localhost:5000 john_doe@localhost

On the remote container:
paplay /usr/share/sounds/alsa/Front_Center.wav
