pymongo.errors.ServerSelectionTimeoutError: mongodb:27017: [Errno -2] Name or service not known

[alantygel]

Hi,

I have a fresh docker udata install. When I try to run init or create user command, I'm getting a mongodb error:

pymongo.errors.ServerSelectionTimeoutError: mongodb:27017: [Errno -2] Name or service not known

Any ideas?

thanks,
alan
