I am trying to create a NEW custom VM Extension, but this seems to only try and reference a previously created artifact. Is there a way to do what I want and I've just made an error or...?
#Create Custom VM Extension
extension = compute.VirtualMachineExtension(
"commandToExecute" : "mkdir c:\eric"
error: Code="ArtifactNotFound" Message="The VM extension with publisher 'KBC' and type 'CustomScriptExtension' could not be found."
