[avneesh101]

What's Changed

Added 5 missing fields to the Azure Ocean VNG model (__init__.py) identified by comparing against the Java API models:

New Fields

Field	Class	Type
encryption_at_host	NodePoolProperties	bool
local_dns_profile	NodePoolProperties	LocalDnsProfile
preferred_vm_sizes	VmSizes	List[str]
restrict_scale_down	VirtualNodeGroupTemplate	bool
scheduling	VirtualNodeGroupTemplate	Scheduling

New Class

• LocalDnsProfile — with mode: str, vnet_d_n_s_overrides: dict, kube_d_n_s_overrides: dict

Files Changed

• spotinst_sdk2/models/ocean/azure/__init__.py — model changes
• spotinst_sdk2/version.py — bumped to 3.22.1
• CHANGELOG.md — updated
• docs/models/ocean/azure.md — updated class signatures

Testing

All fields verified end-to-end against the Spotinst API (create VNG → GET assert → UPDATE → GET assert → DELETE).
