Hello, Is there any guide on how you are able to prepare a blob storage in azure to work with as an storage block? thanks in advance

The first two screenshots here show how you set up the storage block: https://discourse.prefect.io/t/how-to-deploy-prefect-2-0-flows-to-azure/1312 You can find your storage connection string, storage account name, in the Azure portal: search for 'Storage Accounts', open the page for the storage account that houses the container/blob you want to use, and click on 'Access Keys'. That page has all three values the block page asks for.

Thank you very much. It is working! but I have some doubts on what is the deployment.apply is doing, cause I'm not sure if it is uploading all of the data. because it is also uploading my venv library.

You're welcome!
