Launch Azure Container Service on Upload to Blob Storage

Question

I have a use case where I'd like to launch a job on an Azure Container Service cluster to process a file being uploaded to Blob storage. I know that I can trigger an Azure Functions instance from the upload, but I haven't been able to find examples in the documentation of starting a job within Functions.

This diagram illustrates the AWS equivalent of what I want:

Thanks!

The Azure Event Grid feature is what you need. It is still in preview, but you can subscribe to the Blob Created event. You can set the subscriber endpoint to an Azure Function that puts a message in a queue to trigger your job, or you can expose a service on your cluster that will accept the request and do whatever you need done. Microsoft provides a guide at https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-quickstart?toc=%2fazure%2fevent-grid%2ftoc.json#create-a-message-endpoint
