SKS: CPU Manager policies for Karpenter-provisioned nodes

Exoscale SKS now supports configuring Kubernetes CPU Manager policies for nodes provisioned by Karpenter. You can define the kubelet CPU Manager configuration in an ExoscaleNodeClass and apply it consistently to every node created from that class.

What this enables

• More predictable performance: Assign exclusive CPUs to eligible workloads that are sensitive to latency or CPU contention.
• Consistent node configuration: Apply the selected CPU policy automatically to new nodes provisioned by Karpenter.
• Flexible workload isolation: Reserve CPU capacity for Kubernetes and system components while keeping application resources separate.

Why it matters

CPU Manager policies give teams greater control over how processor resources are allocated across their SKS workloads. This is especially useful for high-performance, real-time, and other compute-intensive applications that benefit from stable CPU placement.
