Azure IoT Edge

Azure IoT Edge moves analytics and logic out of the cloud and onto your on-premises devices. Using a cloud interface, you can deploy either Azure service logic or your own code to devices without having to physically access them. And offline capabilities mean that you can extract business insights anywhere, without worrying about maintaining constant communication with a cloud service.

More details about the services are available in the documentation.

  1. Support X.509 certificates in IoT Edge for Raspbian (Linux) and the Device Provisioning Service (DPS)

    We are using a Raspberry Pi Zero W for a large-scale IoT sensor rollout. Our plan is to use IoT Edge on Raspbian (Linux) to run our Python software on the devices and leverage the IoT hub to deploy our code via modules to our devices. We also want to use the IoT hub Device Provisioning Service to further automate the rollout of newly added devices. The goal is to make this scalable to 1.000 devices as a Proof of Concept, and in a production phase scale up to 50.000-100.000 devices.

    We've tried to follow the tutorial by Microsoft to…

  2. IoT Hub device and module twins limit.

    There is limit of 8KB limit for IoT Hub device twins. What’s the limit on module twins? How much total size allowed for both device twins and module twins? Is any plan to enhance the size of both twins in GA or later release?

    IoT Edge now matches the increased IoT Hub limits:
    – Device and module twin size increase from 8kb to 32kb
    – Increase levels of nesting in a device and module twin from 5 levels to 10 levels
    – Increase size of key/value properties: key size from 64b to 1k, value size from 512b to 4k
    These changes are included in the 1.0.8.4 release that was published this past Monday.

  5. Increase 512 byte limit for create container options

    I experienced not being able to fully utilize everything I need to do with the create container options because of the 512 byte limit. Can we increase this dramatically? 512 bytes is not much at all.

    The 1.0.4 release of Azure IoT Edge allows the createOptions field to have configurations longer than 512 bytes. Longer createOptions can easily be set from the Azure Portal or Azure IoT Edge extension (version 1.6) for VS Code. Details on the bug and fix can be found in GitHub issue #396.

  6. Start the clean-up thread for messages that exceeded time-to-live directly or make the time configurable

    Background: The edgeHub stores by default IoT Hub messages in rocksdb which couldn't be sended. After 30min a clean up threads starts which is dropping messages from rocksdb where the TTL of messages is exceeded. The TTL of edgeHub can be controlled e.g. by IoT Hub -> Edge Devices -> Set Modules -> Environment Settings and has default of 2 hours. In our scenario based on high load, we need to reduce the TTL to e.g. 1 minute and have to wait 30mins (20-30GB data in rocksdb) until the clean up thread is starting.

    Feature Request: Start the clean up…

  7. Support for .NET Core 3.0 and .NET core 3.1

    IoT edge supports .NET core 2.0 only. But latest vesions are 3.0 and 3.1. And moreover 2.0 isn't even LTS release.
    Or does it support all versions greater than 2.0?

  10. Edit module twin in a programmable way

    All tutorials and examples always edits module twin manually by user copy pasting JSON. Please specify sample source or tutorial for editing module twins programmatiically ( nodeJS/C#)? Expecting anything similar to https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-node-node-twin-getstarted

  11. Log a Warning if messages are deleted from the StoreAndForward/offline cache (because of TTL)

    Currently there is no way to figure out that messages were deleted because of the Time To Live/TTL StoreAndForward configuration. There should be a warning in the Logs if this happens to hint the deletion of messages that were not sent to IoT Hub. Ideally there is a configurable second warning before this happens (e.g. 10 minutes before messages get deleted because of TTL).
    In addition it would be great to add more control to the StoreAndForward/Caching/Queuing functionality of messaging - refer to ideas https://feedback.azure.com/forums/907045-azure-iot-edge/suggestions/33534802-more-options-or-configuration-parameters-of-stor and https://feedback.azure.com/forums/907045-azure-iot-edge/suggestions/36632884-low-bandwidth-partially-connected-message-deliv

  12. IoT-Edge Windows preview state

    I would like to know if it is already foreseeable when Windows will be officially supported by the IoT Edge Runtime and will leave the preview state? Is it planned to support only x64 or are there versions of IoT Edge runtime planned for x86 or ARM?

    As it is mentioned here, it is still in preview: https://docs.microsoft.com/en-us/azure/iot-edge/how-to-install-iot-edge-windows

  13. Is IoT Edge ML module supported by RHEL 7.5 ?

    Is IoT Edge ML module supported by RHEL 7.5 ? I follow https://docs.microsoft.com/en-us/azure/iot-edge/tutorial-deploy-machine-learning for configuring IoT Edge on RHEL 7.5. edgeAgent failed to start.

  14. Make Azure IoT Edge Daemon depend on Docker

    I am running an instance of IoT Edge on an RaspberryPi with only 4GB disk. So i have to move the docker images to an external drive.

    Now docker took longer to start up...

    The iotedged ist starting and hung in "Initializing..."

    I added a dependency tto docker.service to fix this.

    After= ... docker.service
    Require= ... docker.service

    In the iotedge.service file ALL required other services should be set to avoid such problems.

  17. Enable proxy environment Support for Blob Storage Module

    Currently the blob storage module are not supporting proxy environment. Which means collected data are not sync up with the Azure Blob Storage on the cloud. It would be great if we able to enable the proxy environment support for blob storage module under the IoT Edge.

    Can we have this module to support proxy environment ?

    Thanks !

  18. Deployment task in Azure Pipelines not working

    The Azure IoT Edge task in Azure Pipelines seems to be broken for deployment. It was working fine for a while, but last night it started failing with "ERROR: The 'jsonschema' distribution was not found and is required by the application".

  19. Common project strucuture for iot edge solutions

    To integrate iot edge solutions into development tools, I found different possibilities.

    -The Visual Studio solution: https://docs.microsoft.com/de-de/azure/iot-edge/how-to-visual-studio-develop-module

    Both ways uses different project structures. They are not interchangeable. Not only for development tools. I run into problems, when I want to use a iot edge project in azure pipelines with offical azure Iot-Edge-Build-plugin. (https://github.com/MicrosoftDocs/azure-docs.de-de/issues/341#issuecomment-493401019)
    I think it would be useful, if there is a common project structure for iot-edge solutions.

    The following video shows how a VS project and VS Code project work together in a dev team.

    https://channel9.msdn.com/Shows/Internet-of-Things-Show/Deep-Dive-Using-CICD-to-Deploy-IoT-Edge-Modules-with-Confidence

    Developers can also open VS IoT Edge project in VS Code now.

    We don’t support open VS Code project in VS because
    - Overall we don’t see the between Visual Studio and VS Code often, due to the different developer cohorts who use these tools.
    - From tech perspective, VS Code has got more language support, VS requires a *.sln file.

  20. Stop Module Only After Container Download Completes Successfully

    I have noticed that when you deploy an update to a module, edgeAgent stops the module to update, downloads the new image, and then runs the new image of the module. This works fine when the connection is good and/or the image is small. When the connection is poor and/or the image is large, however, it may take a while to update which means the module is down for a while.

    To increase availability, particularly with bad connections/big images, why doesn't edgeAgent only stop the old module once the new one has finished updating? I've had experiences where a module…
