So we created an aks cluster and azure created virtual machine scale sets in the resource group of the cluster.
Yesterday when i upgraded the image(via terraform) of the scale sets nothing happend to the version of the node.
And today when i looked the nodes had the identical version to the scale sets.

Now my question is are the nodes the equivalent of scale sets or am i missing some mechanic of azure aks?

Kind regards
Yasin

    Hi,
    Yes, AKS creates vm scale set, but it is highly not recommended to change the scale set resources directly. You should use only the operations that are available via the AKS resource. So I would do a new deployment and not temper the scale set directly anymore.
