Announcing Public Preview of the Open Service Mesh (OSM) AKS add-on

Please be aware we are updating the docs to include the az feature registration needed to enable subscription to get the OSM AKS add-on. You can follow the below direction prior to going through the MS Docs walkthrough.  Sorry for the inconvenience 😊.

Register the `AKS-OpenServiceMesh` feature flag by using the az feature register command:

az feature register --namespace "Microsoft.ContainerService" --name "AKS-OpenServiceMesh"

It takes a few minutes for the status to show *Registered*. Verify the registration status by using the az feature list command:

az feature list -o table --query "[?contains(name, 'Microsoft.ContainerService/AKS-OpenServiceMesh')].{Name:name,State:properties.state}"

When ready, refresh the registration of the *Microsoft.ContainerService* resource provider by using the az provider register command:

az provider register --namespace Microsoft.ContainerService
