I have project A that creates a dns zone on azure, and I have project B that needs to find out some specific records in the zone. How can I tell project B to achieve that (other than using stack reference)?

You could look up the DNS zone, just as if it weren't created by Pulumi at all.

How to look it up pragamtically?

You could use

getZone

if you just want info from it (https://www.pulumi.com/registry/packages/aws/api-docs/route53/getzone/) or use

Zone.get

if you want a read-only Pulumi resource (https://www.pulumi.com/registry/packages/aws/api-docs/route53/zone/#look-up).

Great! That really helps
