Azure Germany, US or China

If you want to use the site-extension (only possible with version 0.5.1 or newer) in one of the regional data-centers you have to add some extra app settings.

The following app settings must be set:

Key	Value
letsencrypt:AzureAuthenticationEndpoint	The ActiveDirectoryAuthority (e.g. https://login.microsoftonline.de/)
letsencrypt:AzureTokenAudience	The ActiveDirectoryServiceEndpointResourceId (e.g. https://management.core.cloudapi.de/)
letsencrypt:AzureManagementEndpoint	The ResourceManagerUrl (e.g. https://management.microsoftazure.de/)
letsencrypt:AzureDefaultWebSiteDomainName	The Azure Web Sites default domain name (e.g. azurewebsites.net)

It is possible to get the values for the different regions using the powershell command

Get-AzureEnvironment
