Using a different storage account

README.md

This explains how to use a different storage account (other than the one Azure Functions does) for consuming events in module 1 of Microsoft Azure Developer: Develop Event Based Solutions course.

1. Create a new app settings key and for its value have the connection string value for the storage account that contains the images and grayscale containers.
   • For this example, we'll call that key EventImageStorage
2. In the Grayscale.cs file, update the function's Blob declaration attribute to read:

   [Blob("{data.url}", FileAccess.Read, Connection = "EventImageStorage")] Stream inputBlobStream,

3. Then further down in the body of the function, when you new up the BlobServiceClient, change that to:

   var outputBlobServiceClient = new BlobServiceClient(
       Environment.GetEnvironmentVariable("EventImageStorage")
   );

What you're doing is making sure the blob handling points at the correct Azure Storage account. I was using the account as specified by AzureWebJobsStorage. But we don't need to.
