Azure IoT Operations deployment fails with Helm error

Question

I created an AKS EE K3s cluster on my local machine and successfully connected it to Azure Arc. All checks pass for the IoT Operations deployment, but it failed with the following error. Any guidance on what to check will be appreciated.

Answer 1

Minimum requirement for AKS EE k3S is 4 cores with 16 GB of memory for AIO 1.0.9 deployment. Recommendation is to use 8 cores with 32 GB. Unfortunately you'll have to change the provide Powershell script manually. AKS EE support is still in preview, but I've managed to get it working on an Azure VM and Intel NUC machine.

Answer 2

In the end I re-deployed the AKS EE cluster using the (recommended) PowerShell script. This has worked but does beg the question if people are going to deploy to a CNCF conformant K*s cluster what the difference was.
