How to create Redis cache using Azure powershell?

Question

Is it possible to create Redis cache using Azure powershell? I tried to search the solution from internet, but cannot find one.

Answer 1

I ran into this issue as well and the answer was not obvious when trying to write a deploy script in powershell.
The issue stems from how you setup your azure subscription in powershell. If you chose to use certificate-based authentication (i.e. import-azurepublishsettings), then any cmdlet using the resource management api will NOT work, failing with an authorization
header error. Powershell even lets you know. After you have setup your subscription, run Get-AzureSubscription and look for the line starting with "SupportedModes". You will notice that only AzureServiceManagement shows up. You need it to contain
AzureResourceManager as well. 
The Add-AzureAccount cmdlet will add the AzureResourceManager mode to your subscription
But you want to use this in an automated fashion? Read on.
1) If your Microsoft account is not also linked to an organizational account OR your organizational account contains the subscription you are attempting to use, then simply login using Add-AzureAccount. That will give you access to both modes.
2) If you do have a Microsoft account linked to an organizational account, you can use Active Directory service principals. Be warned that it requires setup, but it will give you access to AzureResourceManager cmdlets. Here is a guide: http://blog.davidebbo.com/2014/12/azure-service-principal.html.
There is another caveat: you will not be able to use both modes in the course of your script with a service principal account. Service Principal accounts use Role Based Access Control, which is not currently supported in the Service Management API. I have
not found a great solution to overcome this--other than creating a new Microsoft account and linking that to the subscription you want to use which I find distasteful.
Hope this helps.
