OS Support Matrix

This document lists the versions of Kubernetes components included in different MicroOS images.

CPU BaselineVersion Mapping

CPU Baseline

ACP-provided MicroOS 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 MicroOS images.

INFO

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.
