Default Azure deployment script
## Octopus Azure deployment script, version 1.0
## --------------------------------------------------------------------------------------
##
## This script is used to control how we deploy packages to Windows Azure.
##
## When the script is run, the correct Azure subscription will ALREADY be selected,
## and we'll have loaded the neccessary management certificates. The Azure PowerShell module
## will also be loaded.
##
## If you want to customize the Azure deployment process, simply copy this script into
## your NuGet package as DeployToAzure.ps1. Octopus will invoke it instead of the default
## script.
##
## The script will be passed the following parameters in addition to the normal Octopus
## variables passed to any PowerShell script.
##
## $OctopusAzureSubscriptionId // The subscription ID GUID
## $OctopusAzureSubscriptionName // The random name of the temporary Azure subscription record
## $OctopusAzureServiceName // The name of your cloud service
## $OctopusAzureStorageAccountName // The name of your storage account
## $OctopusAzureSlot // The name of the slot to deploy to (Staging or Production)
## $OctopusAzurePackageUri // URI to the .cspkg file in Azure Blob Storage to deploy
## $OctopusAzureConfigurationFile // The name of the Azure cloud service configuration file to use
## $OctopusAzureDeploymentLabel // The label to use for deployment
## $OctopusAzureSwapIfPossible // "True" if we should attempt to "swap" deployments rather than a new deployment
