WHAT

🤖[deprecated] Generated by Copilot at 6b9c85a

Increased cpu limit for kube-ovn-cni container in charts/values.yaml to enhance CNI performance and stability.

🤖[deprecated] Generated by Copilot at 6b9c85a

kube-ovn-cni needs
more cpu cores to attach
pods in autumn wind

HOW

🤖[deprecated] Generated by Copilot at 6b9c85a

• Increase the cpu limit for the kube-ovn-cni container to 2 cores (link). This improves the performance and stability of the CNI plugin, which attaches pods to the OVN network. The change is based on user feedback and OVN documentation recommendations.
