Upgrade AKS node pool version#
Reliability · Azure Kubernetes Service · Rule · 2020_06 · Important
AKS node pools should match Kubernetes control plane version.
Description#
AKS supports multiple node pools. In a multi-node pool configuration, it is possible that the control plane and node pools could be running a different version of Kubernetes.
Different versions of Kubernetes between the control plane and node pools is intended as a short term option to allow rolling upgrades. For general operation, the control plane and node pool Kubernetes versions should match.
Recommendation#
Consider upgrading node pools to match AKS control plan version.
