Automatic tagging

skhamitkar — Wed, 15 Oct 2025 12:57:54 GMT

Hi community can anyone solve my problem?

Scenario: I want to auto tag all the workloads belonging to ms-prod, and ms-app namespaces which are under ms-prodcution cluster. Tell me how can i do this. Using entity selector expression. So far i was using this expression but its not working

type(CLOUD_APPLICATION).toRelationships.isNamespaceOfCa(type(CLOUD_APPLICATION_NAMESPACE),entityName.in("ms-prod","ms-app").toRelationships.isClusterOfNamespace(type(KUBERNETES_CLUSTER),entityName("ms-prodcution"))

also, If you guys can send me the documentation where i can find these relationship detail then that would be helpful

Hello @skhamitkar

Try the following.

type(CLOUD_APPLICATION),toRelationships.isNamespaceOfCa(type(CLOUD_APPLICATION_NAMESPACE),entityName.in("ms-prod","ms-app"),toRelationships.isClusterOfNamespace(type(KUBERNETES_CLUSTER),entityName("ms-prodcution")))

on aside note with Kubernetes tagging, I really wish we could use placeholders with the entity selector tag method.
