OS Support Matrix
This document lists the versions of Kubernetes components included in different Alauda OS images.
CPU Baseline
ACP-provided Alauda OS images on x86_64 require CPUs that meet the x86-64-v2 ISA baseline. x86_64 hardware that does not support x86-64-v2 is outside the supported baseline for these images.
This requirement applies when you create or upgrade cluster nodes with ACP-provided Alauda OS images.
Version Mapping
The kube-ovn (chart) column is the acp/chart-cpaas-kube-ovn Helm chart version, which tracks the ACP release line (for example, ACP v4.2.2 ships chart v4.2.24). It is not the Kube-OVN component (binary) version such as v1.14.x or v1.15.x.
Use this chart version — not the component version — when you set the cpaas.io/kube-ovn-version annotation on the Cluster resource and when you patch the cni-kube-ovn AppRelease spec.source.charts[0].targetRevision. See the provider-specific upgrade guides for the procedure.
Image Format by Provider
A single Alauda OS image build (one row in the matrix above) is delivered in different file formats. Choose the format that matches your infrastructure provider when you download the image and upload it to the target platform:
The format does not change the OS content — it only changes the packaging for the target platform. The version identifier in the matrix above is format-independent; append the provider's format when you reference the downloaded file.
