nebula graph - error on trying to create my first space: Host not enough

Question

going through the kick start i have the DB running as a docker extension and have logged in.

https://docs.nebula-graph.io/3.5.0/2.quick-start/1.quick-start-workflow/

CREATE SPACE bverse(partition_num=10, replica_factor=1, vid_type=fixed_string(30));

gives the error. tried reducing partitions, no luck

digging around i found something about setting up hosts

ADD HOSTS 192.168.10.100:9779, 192.168.10.101:9779, 192.168.10.102:9779;

which runs OK...

but CREATE SPACE still fails.

is there a getting started that actually works? this isn't very reassuring.
