# this script will show how to delete containers with a specific prefix # the prefix this will search for is "image". # before running this, you need to create a storage account, create some containers, # some having the same prefix so you can test this # note: this retrieves all of the matching containers in one command # if you are going to run this against a storage account with a lot of containers # (more than a couple hundred), use continuation tokens to retrieve # the list of containers. We will be adding a sample showing that scenario in the future. # these are for the storage account to be used # and the prefix for which to search $resourceGroup = "containerdeletetestrg" $location = "eastus" $storageAccountName = "containerdeletetest" $prefix = "image" # get a reference to the storage account and the context $storageAccount = Get-AzureRmStorageAccount ` -ResourceGroupName $resourceGroup ` -Name $storageAccountName $ctx = $storageAccount.Context # list all containers in the storage account Write-Host "All containers" Get-AzureStorageContainer -Context $ctx | select Name # retrieve list of containers to delete $listOfContainersToDelete = Get-AzureStorageContainer -Context $ctx -Prefix $prefix # write list of containers to be deleted Write-Host "Containers to be deleted" $listOfContainersToDelete | select Name # delete the containers; this pipes the result of the listing of the containers to delete # into the Remove-AzureStorageContainer command. It handles all of the containers in the list. Write-Host "Deleting containers" $listOfContainersToDelete | Remove-AzureStorageContainer -Context $ctx # show list of containers not deleted Write-Host "All containers not deleted" Get-AzureStorageContainer -Context $ctx | select Name
