How do I determine if a storage container or blob exists?

See original GitHub issue

In older versions of the Azure SDK for Python, I could call BaseBlobService.exists() to check if a container or blob exists.

I don’t see any equivalent function in the documentation for BlobServiceClient, ContainerClient or BlobClient. The functions to create/overwrite a container or blob will throw an error if the object already exists, but there are times when I just want to verify something exists without modifying it.

What is the correct way to check if a blob exists in azure-storage-blob v12+?

Hi @dharmab

Thanks for reaching out! Currently you can use blob_client.get_blob_properties() and it will throw ResourceNotFoundError if the blob/container/blob_snapshot doesn’t exist.

We have an feature request to add exists() api, so users will be less confused about this.
