[jczhong84]

does it work by just running make and choose the demo environment setup?

[czgu]

did you add DATABASE_CONN: ~ to querybook_config.yaml

[bruumnml]

did you add DATABASE_CONN: ~ to querybook_config.yaml

yes, it is configured and added in the docker-compose file file

does it work by just running make and choose the demo environment setup?

i have my databases in different instances, the worker,web and scheduler run in a separated EC2 instance
