Delete containers based on container name prefix

This script first creates a few sample containers in Azure Blob storage, then deletes some of the containers based on a prefix in the container name.

To run this sample, make sure you have installed the latest Azure CLI 2.0. To start, run az login to create a connection with Azure.

This sample works in a Bash shell. For options on running Azure CLI scripts on Windows client, see Running the Azure CLI in Windows.

If you don't have an Azure subscription, create a free account before you begin.

Sample script

export AZURE_STORAGE_ACCOUNT=<storage-account-name>
export AZURE_STORAGE_ACCESS_KEY=<storage-account-key>

# Create a resource group
az group create --name myResourceGroup --location eastus

# Create some test containers
az storage container create --name test-container-001
az storage container create --name test-container-002
az storage container create --name production-container-001

# List only the containers with a specific prefix
az storage container list --prefix "test-" --query "[*].[name]" --output tsv

echo "Deleting test- containers..."

# Delete 
for container in `az storage container list --prefix "test-" --query "[*].[name]" --output tsv`; do
    az storage container delete --name $container

echo "Remaining containers:"
az storage container list --output table

Clean up deployment

Run the following command to remove the resource group, remaining containers, and all related resources.
