Azure function to post a daily image of my smartGarten timelapse to instagram (See https://www.instagram.com/philipps_smartgarten/).

Currently a Raspberry Pi with a hd camera module takes every 15 minutes a picture and uploads it to a Azure Blob Storage Container using two Azure IoT Edge Modules (See https://github.com/smagribot/iot-edge-rpicamera).

The functions starts daily at 13 o'clock (UTC) and searches for images from today with the prefix filter, because the images are in the format yyyy-MM-dd_HH-mm-ss.jpg. Then a sas token url gets created for the latest image of today, so the Meta Api can download the picture and create a image container which can be published.

Please read the documentation for more information on how to create a developer account and all the prerequisites to use this function.
