How do you capacity plan for CRD versioning?

Effective capacity planning for Custom Resource Definition (CRD) versioning is crucial for maintaining Kubernetes workload stability and scalability. This involves anticipating resource usage based on version changes and ensuring that the infrastructure can support different CRD versions without degradation of service.

        <?php
        // Example of capacity planning for CRD versioning
        class CRDManagement {
            public function calculateNeededResources($currentVersion, $newVersion) {
                $currentResources = $this->getCurrentResources($currentVersion);
                $newResources = $this->getCurrentResources($newVersion);
                
                $requiredIncrease = $newResources - $currentResources;

                if ($requiredIncrease > 0) {
                    $this->scaleUpResources($requiredIncrease);
                } else {
                    $this->scaleDownResources(-$requiredIncrease);
                }
            }

            private function getCurrentResources($version) {
                // Fetch resource requirements for the given version
                // This is a placeholder for actual resource fetching logic
                return rand(50, 150); // Simulated resource amount
            }

            private function scaleUpResources($increase) {
                echo "Scaling up resources by $increase units for better performance.\n";
            }

            private function scaleDownResources($decrease) {
                echo "Scaling down resources by $decrease units to optimize costs.\n";
            }
        }

        // Usage
        $crd = new CRDManagement();
        $crd->calculateNeededResources('v1', 'v2');
