Invoke-AzAksRunCommand uses an out of date version of kubectl

[w3bward]

Description

I'm not sure where to raise this issue, but I believe the way that Invoke-AsAksRunCommand works is that it spins up a pod from a Microsoft maintained image to actually execute the command. Currently it looks like this container image has kubectl version 1.20.13, which may have compatibility issues depending on the Kubernetes version running on your AKS cluster.

In my use case, I'm trying to create a Powershell function that can be used to easily create a job from a cronjob on demand, but the API for doing so in kubectl v1.20.13 is not compatible with the API on our cluster running kubernetes v1.22.6.

Ideally, there would be different container images for different versions of kubernetes, and Invoke-AzAksRunCommand would select the appropriate image based on the cluster version.

Hi @w3bward , could you please share some more error message of your command? What's the compatibility issues looks like? Is it reject by service or some result is not as expected?
