Use a Label Group in a Rule
When you use a label group in a rule, it is expanded into multiple rules. Cross-communication is allowed.
For example, the Non-Prod label group is used again here, but in the rule, not the scope, which allows for cross-communication.
Scope:
App: HRM
Env: All
Loc: US
Rule:
Providers: Non-prod DB
Services: MySQL
Consumers: Non-prod DB
This means “allow MySQL from Non-Prod DB to Non-Prod DB for the HRM application in All environments located in the US" and would allow the following communication:
HRM | Dev | US | DB ← HRM | Dev | US | DB
HRM | Dev | US | DB ← HRM | QA | US | DB
HRM | Dev | US | DB ← HRM | Stage | US | DB
HRM | QA | US | DB ← HRM | Dev | US | DB
HRM | QA | US | DB ← HRM | Stage | US | DB
