How use DVC with Azure Blob Storage

DVC supports AWS S3, Google Cloud Storage, Microsoft Azure Blob Storage. However, the instruction is only for AWS S3. How to use DVC with Microsoft Azure Blob Storage?

Hi @felkost !

I’ve seen you asked it on discord too :slightly_smiling_face: , but just for the record: Azure example is available here https://dvc.org/doc/commands-reference/remote-add .

Thanks,
Ruslan

The above link doesn’t work.

In particular, I am interested in using dvc remote with a SAS token. When I add the azureblob remote via https:// link to DVC and initiate dvc push, it returns '405 The resource doesn't support specified Http Verb.' error.

To sum app, providing remote as:

  https://wasburl/container/?sig=<sastoken>

results in

  dvc.exceptions.HTTPError: '405 The resource doesn't support specified Http Verb.'

What I read in different forums, it appears Azure requires Cross-Origin Resource Sharing (CORS) headers and DVC doesn’t support it. I guess this post could be a feature request to DVC to include CORS headers.

Any ideas?
