The operation to create or update the VMSS VM extension.

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/virtualMachineScaleSets/{vmScaleSetName}/virtualMachines/{instanceId}/extensions/{vmExtensionName}?api-version=2024-07-01

URI Parameters

Name	In	Required	Type	Description
instanceId	path	True	string	The instance ID of the virtual machine.
resourceGroupName	path	True	string	The name of the resource group.
subscriptionId	path	True	string	Subscription credentials which uniquely identify Microsoft Azure subscription. The subscription ID forms part of the URI for every service call.
vmExtensionName	path	True	string	The name of the virtual machine extension.
vmScaleSetName	path	True	string	The name of the VM scale set.
api-version	query	True	string	Client Api Version.

Request Body

Name	Type	Description
location	string	The location of the extension.
properties.autoUpgradeMinorVersion	boolean	Indicates whether the extension should use a newer minor version if one is available at deployment time. Once deployed, however, the extension will not upgrade minor versions unless redeployed, even with this property set to true.
properties.enableAutomaticUpgrade	boolean	Indicates whether the extension should be automatically upgraded by the platform if there is a newer version of the extension available.
properties.forceUpdateTag	string	How the extension handler should be forced to update even if the extension configuration has not changed.
properties.instanceView	VirtualMachineExtensionInstanceView	The virtual machine extension instance view.
properties.protectedSettings	object	The extension can contain either protectedSettings or protectedSettingsFromKeyVault or no protected settings at all.
properties.protectedSettingsFromKeyVault	KeyVaultSecretReference	The extensions protected settings that are passed by reference, and consumed from key vault
properties.provisionAfterExtensions	string[]	Collection of extension names after which this extension needs to be provisioned.
properties.publisher	string	The name of the extension handler publisher.
properties.settings	object	Json formatted public settings for the extension.
properties.suppressFailures	boolean	Indicates whether failures stemming from the extension will be suppressed (Operational failures such as not connecting to the VM will not be suppressed regardless of this value). The default is false.
properties.type	string	Specifies the type of the extension; an example is "CustomScriptExtension".
properties.typeHandlerVersion	string	Specifies the version of the script handler.

Responses

Name	Type	Description
200 OK	VirtualMachineScaleSetVMExtension	OK
201 Created	VirtualMachineScaleSetVMExtension	Created
Other Status Codes	CloudError	Error response describing why the operation failed.
