Azure:manage Anonymous read access to containers and blobs

Grant anonymous users permissions to containers and blobs

By default, a container and any blobs within it is accessed only by the owner of the storage account. To give anonymous users read permissions to a container and their blobs, can set the container permissions to allow publ IC 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 is read via anonymous request, but container data i s not available. Clients cannot enumerate blobs within the container via anonymous request.

• No public read Access:container and BLOB data can is read by the account owner only.
