Execute an arbitrary piece of code with a temporary file uploaded to azure

A short one today.

My use case is to run a Set-AzureRmVMCustomScriptExtension command. For it to work i need the script to be somewhere accessible by the VM.

Nothing to fancy. Might be useful for someone (or a future version of me). It creates a temp container, uploads the file, invokes the code passing in the URI, and whatever happens the container will be deleted. Assumes a connection to azure and an already existing storage account.

Just to highlight an interesting point

“temp-container-” + (-join ((97..122) | Get-Random -Count 5 | % {[char]$_}))

Initially i just had “temp-container” but when running 2 times in a row I got an error saying that the container could not be created as it was being deleted. So I found a way to generate random letters and now it creates an “unique” container each time.
