I get as far as the : docker compose exec nodebb ./nodebb setup step.

Other container with mongodb is up and running fine...

Whatever I do I keep getting the below message :

This looks like a new installation, so you'll have to answer a few questions about your     environment before we can proceed.
Press enter to accept the default setting (shown in brackets).

I tried :

• setting env variables in Docker Compose file
• copying config.json file in the DockerFile

All gets to this error. Why ? ;-(
