Please set the environment variables DB_USER, DB_PASSWORD. You can so so by editing them in the .env file in /etc/rasa. E.g.

RASA_X_DEMO_VERSION=0.19.1
RASA_VERSION=1.1.4
CORE_SDK_VERSION=1.1.0
# runtime arguments
RASA_TOKEN=rasatoken
PASSWORD_SALT=saltysalt
JWT_SECRET=jwt
RASA_X_TOKEN=rasaxtoken
RABBITMQ_PASSWORD=password

DB_USER=admin
DB_PASSWORD=password

DB_DATABASE should already be set, same for DB_LOGIN_DB. Can you share your docker-compose file?

Sorry that this step is currently missing in the docs, will update that asap
