Definitions

Name	Description
ApiError	Api error.
ApiErrorBase	Api error base.
CloudError	An error response from the Compute service.
ImageReference	Specifies information about the image to use. You can specify information about platform images, marketplace images, or virtual machine images. This element is required when you want to use a platform image, marketplace image, or virtual machine image, but is not used in other creation operations. NOTE: Image reference publisher and offer can only be set when you create the scale set.
InnerError	Inner error details.
RollbackStatusInfo	Information about rollback on failed VM instances after a OS Upgrade operation.
RollingUpgradeProgressInfo	Information about the number of virtual machine instances in each upgrade state.
UpgradeOperationHistoricalStatusInfo	Virtual Machine Scale Set OS Upgrade History operation response.
UpgradeOperationHistoricalStatusInfoProperties	Describes each OS upgrade on the Virtual Machine Scale Set.
UpgradeOperationHistoryStatus	Information about the current running state of the overall upgrade.
UpgradeOperationInvoker	Invoker of the Upgrade Operation
UpgradeState	Code indicating the current status of the upgrade.
VirtualMachineScaleSetListOSUpgradeHistory	List of Virtual Machine Scale Set OS Upgrade History operation response.

ApiError

Object

Api error.

Name	Type	Description
code	string	The error code.
details	ApiErrorBase[]	The Api error details
innererror	InnerError	The Api inner error
message	string	The error message.
target	string	The target of the particular error.

ApiErrorBase

Object

Api error base.

Name	Type	Description
code	string	The error code.
message	string	The error message.
target	string	The target of the particular error.

CloudError

Object

An error response from the Compute service.

Name	Type	Description
error	ApiError	Api error.

ImageReference

Object

Specifies information about the image to use. You can specify information about platform images, marketplace images, or virtual machine images. This element is required when you want to use a platform image, marketplace image, or virtual machine image, but is not used in other creation operations. NOTE: Image reference publisher and offer can only be set when you create the scale set.

Name	Type	Description
communityGalleryImageId	string	Specified the community gallery image unique id for vm deployment. This can be fetched from community gallery image GET call.
exactVersion	string	Specifies in decimal numbers, the version of platform image or marketplace image used to create the virtual machine. This readonly field differs from 'version', only if the value specified in 'version' field is 'latest'.
id	string	Resource Id
offer	string	Specifies the offer of the platform image or marketplace image used to create the virtual machine.
publisher	string	The image publisher.
sharedGalleryImageId	string	Specified the shared gallery image unique id for vm deployment. This can be fetched from shared gallery image GET call.
sku	string	The image SKU.
version	string	Specifies the version of the platform image or marketplace image used to create the virtual machine. The allowed formats are Major.Minor.Build or 'latest'. Major, Minor, and Build are decimal numbers. Specify 'latest' to use the latest version of an image available at deploy time. Even if you use 'latest', the VM image will not automatically update after deploy time even if a new version becomes available. Please do not use field 'version' for gallery image deployment, gallery image should always use 'id' field for deployment, to use 'latest' version of gallery image, just set '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Compute/galleries/{galleryName}/images/{imageName}' in the 'id' field without version input.
