List down all container within a storage account of azure through databricks

Question

I, want to dynamically get all storage account and containers within from an azure subscription by databricks.
So, that I can go through each file within a container and get the files and their sizes which I have done earlier.
Now I want to dynamically set my storage account and container to process with from a subscription.

Per my experience and based on my understanding for all operations in storage account with databricks, authentication is happening in azure storage account level. In that case, If you are trying to access storage account through service principal or storage account access key both are in storage account level, you can list out the containers within storage account.But we don't have option to list out the storage account within subscription. As workaround, you can use powershell , to get the storage accounts within subscription and pass those value for your logic.

You can use below code, to get the list of containers within storage account.

from azure.storage.blob.blockblobservice import BlockBlobService
blob_service = BlockBlobService(account_name='storageaccount', account_key='accesskey')
containers = blob_service.list_containers()
for c in containers:
    print(c.name)
