Description

Force Delete an AKS node pool is an dangerous option and leads into a downtime.

Thanks @jkroepke LGTM 👍

[stevehipwell]

@jkroepke is there a reason you didn't also fix this for the node pool resource?

[jkroepke]

Oh, that was not in my mind. We had the issues with the ignoring PDB on system pool rotations.

[stevehipwell]

It looks like the azurerm_kubernetes_cluster_node_pool resource has been fixed by #26471.
