Grant anonymous users permissions to containers and blobs
By default, a container and any blobs within it may be accessed only by the owner of the storage account. To give anonymous users read permissions to a container and its blobs, you can set the container permissions to allow public access. Anonymous users can read blobs within a publicly accessible container without authenticating the request.
Containers provide the following options for managing container access:
-
Full public read access: Container and blob data can be read via anonymous request. Clients can enumerate blobs within the container via anonymous request, but cannot enumerate containers within the storage account.
-
Public read access for blobs only: Blob data within this container can be read via anonymous request, but container data is not available. Clients cannot enumerate blobs within the container via anonymous request.
-
No public read access: Container and blob data can be read by the account owner only.
