I've been trying to use the AWS Update-LMFunctionCode to deploy my file to an existing lambda function in AWS.
Differing from the Publish-LMFunction where I can provide just a path to the zipFile (-FunctionZip), the Update-LMFunction wants a memorystream for its -Zipfile argument.
is there an example of loading a local zip file from disk into a memory stream that works? My initial calls are getting errors that the file can't be unzipped...
$deployedFn = Get-LMFunction -FunctionName $functionname
"Function Exists - trying to update"
[system.io.stream]$zipStream = [system.io.File]::OpenRead($zipFile)
[byte]$filebytes = New-Object byte $zipStream.length
[void] $zipStream.Read($filebytes, 0, $zipStream.Length)
$zipString = [System.Convert]::ToBase64String($filebytes)
$ms = new-Object IO.MemoryStream
$sw = new-Object IO.StreamWriter $ms
Update-LMFunctionCode -FunctionName $functionname -ZipFile $ms
$ErrorMessage = $_.Exception.Message
docs for the Powershell function is here: http://docs.aws.amazon.com/powershell/latest/reference/items/Update-LMFunctionCode.html although it wants to live in a frame...
