v0.43.2 - 2019-11-14

Bug Fixes 🐞

• remove support for v1.13.12, v1.14.8, v1.15.5, v1.16.2

We are removing the above Kubernetes versions from aks-engine cluster create support due to identified issues w/ the Azure Kubernetes cloudprovider in those versions for customers running VMSS-backed stateful workloads. See here for the canonical aks-engine issue:

#2312

The fix to Azure cloudprovider is here:

kubernetes/kubernetes#85158

For folks running clusters on the above versions built from AKS Engine v0.42.1 or v0.41.5, if you're experiencing symptoms on your stateful apps (disk attach/detach errors in controller-manager logs are the obvious signal), we recommend a downgrade to n-1 of the version you're on to avoid future recurrence of the symptoms.

aks-engine upgrade --force will enable Kubernetes version downgrade:
