Azure blob storage gen2

Question

I need to restrict uploading files to Blob storage at 18 MB size and allow only .txt extension

Answer 1

@Chandru Sati Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

What's the authorization mechanism that clients use? Attribute-based access control (ABAC) could be used to restrict uploads to .txt files: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-auth-abac. However, content length is not a supported attribute for ABAC conditions.

Please let us know if you have any further queries. I’m happy to assist you further.

In short, these options are not supported on the service side. You'd need to enforce this on the side where the upload takes place

Hi Chandru Sati - Thanks for reaching out over Q&A Forum.

There isn't an option on the Storage side to restrict the upload based on file size or extension and need to be controlled from the application side itself.
