Extension can or can't be installed at 'namespace' level?

[RoFz]

Hi all,

just tried to deploy the extension with:

az k8s-extension create --name azureml-insecure --extension-type Microsoft.AzureML.Kubernetes --config enableTraining=True enableInference=False allowInsecureConnections=True --cluster-type managedClusters --cluster-name <cluster_name> --resource-group <rg_name> --scope namespace --target-namespace <namespace>

But got the following error:

Invalid scope 'namespace'. This extension can't be installed only at 'cluster' scope. Check https://aka.ms/arcmltsg for more information.

The documentation identifies --scope namespace as a valid parameter. I'm a bit puzzled now wondering if the error message contains a typo (can't/can) or if the namespace scope is indeed not supported (probably the latter).

Cheers,
RoFz
