servicefabric-arm-template

Example of ARM template for creating an Azure Service Fabric instance with dedicated premium data disks

Add Data Disks to Template

See: https://github.com/nmehlei/servicefabric-arm-template/blob/master/template.json#L598-L608

"dataDisks": [
	{
		"diskSizeGB": 128,
		"lun": 0,
		"createOption": "Empty",
		"caching": "ReadOnly",
		"managedDisk": {
			"storageAccountType": "Premium_LRS"
		}
	}
]

Add Powershell Script to initialize new Data Disk

See: https://github.com/nmehlei/servicefabric-arm-template/blob/master/PrepareDisk.ps1

Get-Disk |
    Where PartitionStyle -eq 'Raw' |
    Select-Object -First 1 |
    Initialize-Disk -PartitionStyle MBR -PassThru |
    New-Partition -DriveLetter F -UseMaximumSize |
    Format-Volume -FileSystem NTFS -NewFileSystemLabel "Data" -Confirm:$false

This script has to be uploaded to a publicly accessible azure blob storage account.

Schedule invocation of Powershell Script

See: https://github.com/nmehlei/servicefabric-arm-template/blob/master/template.json#L438-L456
