I am studying about Openstack Edge Computing from 

I can separate AZ. Main AZ and Edge AZ for Nova, Neutron and Cinder. Glance Multistore also.

But I cannot figure how we can configure to specify which Glance Stored will be used for launch instances from Edge Site.

And one more question, Will we need setup glance service in Edge sites too?

It will be nice if Glance can be set AZ.

I tried GG but not many docs about it.

Could someone give me some suggestions about ii? Thank you so much
