#AzureIoT – ☁ Azure IoT Edge 1.1.0 release is now GA, experiences upgrading #Ubuntu

Hi !

There is a new version of the Azure IoT Edge module: 1.1.0 (see references). So, I decided to upgrade my 2 test devices and maybe share some lessons learned in the process.

Upgrade on Ubuntu 18.04 on a Raspberry Pi 4

As usual I’ll start with a full update

# Update
sudo -- sh -c 'apt-get update; apt-get upgrade -y; apt-get dist-upgrade -y; apt-get autoremove -y; apt-get autoclean -y'

Similar to the Raspberry Pi OS upgrade process, I found a nice surprise on the update log.

Setting up iotedge (1.1.0-1) ...
===============================================================================

                              Azure IoT Edge

  IMPORTANT: Please update the configuration file located at:

    /etc/iotedge/config.yaml

  with your device's provisioning information. You will need to restart the
  'iotedge' service for these changes to take effect.

  To restart the 'iotedge' service, use:

    'systemctl restart iotedge'

    - OR -

    /etc/init.d/iotedge restart

  These commands may need to be run with sudo depending on your environment.

After this operation, 7168 B of additional disk space will be used.

So, the module is updated. However I need to setup the device provisioning information again and restart the service. In the references section I shared the officials docs for these steps.

Let’s edit the provisioning information

# Update provisioning information (if necessary)
sudo nano /etc/iotedge/config.yaml

My file still have all the valid information (again, like the Raspberry Pi upgrade process)

No changes here, let’s restart IoT Edge

# restart iotedge service
systemctl restart iotedge

Important, authentication is required in this step:

So, I may missed something here. I run the update command for the module, and it’s already on the 1.1 version. However the iotedge list of modules is still using the 1.0

Update runtime settings on Azure IoT Portal

I now I can fix this in the Azure IoT Portal. In the device definition, I need to update the Runtime settings to use the version 1.1. (image is just for reference)

A couple of seconds later, everything works as expected !

Recap

So, the steps to update were these commands

# Update
sudo -- sh -c 'apt-get update; apt-get upgrade -y; apt-get dist-upgrade -y; apt-get autoremove -y; apt-get autoclean -y'

# Update provisioning information (if necessary)
sudo nano /etc/iotedge/config.yaml

# restart iotedge service
systemctl restart iotedge

Then update the Runtime Settings on the Azure IoT Portal.

And restart iotedge one more time !

Happy coding!

Greetings

El Bruno
