Some attributes have values inferred from the definition itself, `app` is read from *app.kubernetes.io/name* annotation or metadata.name, namespace is also read from metadata. Some attributes have values inferred from the definition itself, `app` is read from _app.kubernetes.io/name_ annotation or metadata.name, namespace is also read from metadata.
For secrets and configMaps, if `namespace` is not specified in ref object, it assumes it's in the same namespace as CRD. If you want to specify a default namespace (for example for security reason when assigning secrets:read permission for only one namespace), you can specify `defaultSecretNamespace` and `defaultConfigMapNamespace` in `kubernetes.yaml` file.
