[rjtsdl]

Doc path: azure-cli-samples/compute/vmss.md

# Command

az vm scaleset create -g mygroup -n MyScaleSet --image opensuse --instance-count 3
running az commands with the docker option with tag: latest

# Expected Behavior

No error

# What I get is Error message

az vm: error: argument subcommand: invalid choice: 'scaleset' (choose from 'resize', 'availability-set', 'image', 'boot-diagnostics', 'nic', 'list-sizes', 'extension', 'access', 'generalize', 'redeploy', 'get-instance-view', 'diagnostics', 'wait', 'delete', 'update', 'show', 'disk', 'deallocate', 'list-vm-resize-options', 'restart', 'list-usage', 'stop', 'capture', 'start', 'create', 'open-port', 'list', 'list-ip-addresses')

Looks like cli has changed to
az vmss create -g mygroup -n MyScaleSet --image opensuse --instance-count 3

This would be an issue on docs.
