Hi,

Is it possible we can tag CGI by kubernetes namespace?

Tried it with something like

```markup
type(CONTAINER_GROUP_INSTANCE),fromRelationship.isCgiOfNamespace(type("CLOUD_APPLICATION_NAMESPACE"))

```

and it’s variation but no luck

Hello.

Entities matching:

| type(CONTAINER\_GROUP\_INSTANCE),fromRelationships.isCgiOfNamespace(type(CLOUD\_APPLICATION\_NAMESPACE),entityName(“zoo-app”)) |
| --- |

Result in UI:

Has anyone found a way to do this for CONTAINER\_GROUP rather than CONTAINER\_GROUP\_INSTANCE?

Thanks!

With a bit of help, this worked for me in case anyone needs it&nbsp;👍

type(CONTAINER\_GROUP),toRelationships.isInstanceOf(type(CONTAINER\_GROUP\_INSTANCE),fromRelationships.isCgiOfNamespace(type(CLOUD\_APPLICATION\_NAMESPACE),entityName.startsWith(“\<NAMESPACE NAME\>”)))
