Wrong version in docker-compose.yml ?

[astramax57]

I run

docker-compose pull

and get

ERROR: The Compose file './docker-compose.yml' is invalid because:
services.webserver.volumes contains an invalid type, it should be a string
services.webserver.volumes contains an invalid type, it should be a string

Than I follow this topic and change in docker-compose.yml version from

version: '3'

to

version: '3.7'

that fixed error:

docker-compose pull
Pulling mongodb   ... done
Pulling flask     ... done
Pulling webserver ... done

Hi @astramax57 ,
thank you for raising this issue. For me it also works with just version: '3', but if you faced with the issue I changed it to version: '3.7'. Thank you again.
Meanwhile, I also will be grateful if you share your personal thoughts about topolograph, was it easy to use, did it solve your tasks, probably you want to see some new features? Glad to hear it from you.
