Target - Azure Blob

The Azure Blob target is used to write data to:

  • Azure Blob Storage
  • Azure Data Lake Storage Gen2

Azure Storage Configuration

In order for our application to create and update blobs in your Azure storage container, you need to add a role assignment to the OpenDataDSL application.

Adding an access role

To give access, perform the following:

  • In the Azure Portal, navigate to the Storage Account you want to use
  • Select Access Control (IAM)
  • Click 'Add Role Assignment' from the dropdown add button
  • Select 'Storage Blob Data Contributor' and click 'Next'
  • Click 'Select members'
  • Type 'OpenDataDSL' in the search box and select the application and click 'Select'
  • Click 'Review + assign' (twice)
  • You can optionally add a condition to the role to limit the container or path that the application has access to

The name of this target is BlobTarget

To configure the write blob action, you need to provide the following:
