Powershell Script to remove all Blobs from Storage account

With large number of Blobs in Storage Account, the manual cleanup from the Portal is more complicated and time consuming, as it's per set of 10'000.

This script is simple and and can be executed in background to clean all items from a defined Blob Container. You have to specify the Storage Account connection string and the blob container name.

[string]$myConnectionString = "DefaultEndpointsProtocol=https;AccountName=YourStorageAccountName;AccountKey=YourKeyFromStorageAccountConnectionString;EndpointSuffix=core.windows.net"
[string]$ContainerName = "YourBlobContainerName"
[int]$blobCountAfter = 0
[int]$blobCountBefore = 0

$context = New-AzStorageContext -ConnectionString $myConnectionString

$blobCountBefore = (Get-AzStorageBlob -Container $ContainerName -Context $context).Count
Write-Host "Total number of blobs in the container Before deletion: $blobCount" -ForegroundColor Yellow

Get-AzStorageBlob -Container $ContainerName -Context $context | ForEach-Object {
    $_ | Remove-AzureStorageBlob   # or: Remove-AzureStorageBlob -ICloudBlob $_.ICloudBlob -Context $ctx
}

$blobCountAfter = (Get-AzStorageBlob -Container $ContainerName -Context $context).Count
Write-Host "Total number of blobs in the container After deletion : $blobCount" -ForegroundColor Green

It was used for large blob storage container with more than 5 millions of blob items.
