I have used cloud-init with userdata to bootstrap my service in AWS. I see cloud-init is installed in Azure Ubuntu 12.04 image but I can't find any documentation on how to supply userdata to it.My goal is to use the stock ubuntu image from Azure gallery and run a startup script which would download the bits that would run the service (without having to do ssh). If its possible without cloud-init that would be great as well!
Any pointers will be much appreciated.
