Operating system details
GKE on Azure manages the Azure virtual machine instances and the operating system running on these instances. In Kubernetes versions 1.26 and higher, GKE on Azure uses Ubuntu 22.04 LTS base images for Linux nodes. In Kubernetes versions 1.25 and lower, GKE on Azure uses Ubuntu 20.04 LTS.
The base Azure VM is maintained by Canonical. Google tests these images as part of the GKE on Azure release process. When a cluster or node pool is upgraded, the underlying virtual machine instances are terminated and recreated with the latest OS version.
When an instance launches, GKE on Azure performs additional configuration including:
- Optimizing network settings for Kubernetes
- Installing packages from the Ubuntu archive (Ubuntu only)
- Disabling unattended apt package upgrades and reboots (Ubuntu only)
- Installing Google Kubernetes Engine (GKE) Enterprise edition and Kubernetes binaries
