This function can be triggered by an Event Grid Event for a Storage Account whereas it only listens for BlobCreated and BlobDeleted events. The following table contains the available environment variables.

The storage account access key is needed to access the file share and write / delete the file. The source container is the name of the blob container that will be "monitored". Only events that happen in that particular blob container will be handled. You can either specify a target share to be used for blob to file synchronization or otherwise it will try to sync to a file share that has the same name as the blob container.

Enter the environment variables in the local.settings.json. After that you can check this documentation to test it: https://docs.microsoft.com/en-us/azure/azure-functions/functions-debug-event-grid-trigger-local

• Make the source container variable optional (handle events from all containers)
• Optionally delete empty directories after a a file was deleted
• Add an option to prevent replacing existing files on the share
