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&nbsp;[@skhamitkar](https://community.dynatrace.com/user/86687)

Try the following.

```markup
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.

Hello&nbsp;[@skhamitkar](https://community.dynatrace.com/user/86687)

This is a starting point.

> **[Environment API v2 - Entity selector](https://docs.dynatrace.com/docs/dynatrace-api/environment-api/entity-v2/entity-selector)**
>
> Learn the Environment API v2 entity selector syntax for filtering monitored entities by type, name, tag, management zone, and health state.
