Before you assign it

  • It reaches the data, not just the resource. It has 3 data actions, such as reading blobs, secrets or messages.

What it can do

No control-plane actions.

Data actions

PermissionWhat it allows
Microsoft.Storage/storageAccounts/fileServices/fileshares/files/readReturns a file/folder or a list of files/folders
Microsoft.Storage/storageAccounts/fileServices/fileshares/files/writeReturns the result of writing a file or creating a folder
Microsoft.Storage/storageAccounts/fileServices/fileshares/files/deleteReturns the result of deleting a file/folder

Assign it

Scope it as tightly as you can: a resource or resource group rather than the whole subscription.

azure cli
az role assignment create \
  --assignee "jane.doe@contoso.com" \
  --role "Storage File Data SMB Share Contributor" \
  --scope "/subscriptions/<subscription id>/resourceGroups/<resource group>"
