Kubernetes Resource Quotas and Limits

Help me implement resource management in my Kubernetes cluster.

Cluster resources:
- Total CPU: [cores]
- Total Memory: [GB]
- Namespaces: [list with priority]
- Node types: [instance types]

Requirements:
1. ResourceQuota per namespace
   - CPU/Memory requests and limits
   - Pod count limits
   - PVC count and storage
   - ConfigMap/Secret limits
   - Service limits

2. LimitRange configuration
   - Default requests and limits
   - Min/max constraints
   - Ratio limits

3. Priority classes
   - System critical
   - High priority
   - Normal
   - Low priority/preemptible

4. Namespace allocation strategy
   - Production: [resources]
   - Staging: [resources]
   - Development: [resources]

Include:
- Monitoring for quota usage
- Alerts for approaching limits
- Request handling for quota increases
