Kubernetes resources quotas

• For optimization on a K8s cluster, selecting resource quotas is essential.
• Resource Quotas restrict resource usage per namespace, including CPU, memory, and other objects.
• Create a ResourceQuota object to set memory and CPU quotas.
• Limit memory requests, memory limits, CPU requests, and CPU limits for pods[2].
• Pod quotas restrict the total number of pods in a namespace.
• Control pod creation to optimize resources and prevent overloading[4].
• Resource quotas are crucial in shared environments to prevent resource contention.

• They ensure fair resource allocation among different tenants for cluster stability[3].

• Best Practices
  • Define quotas based on actual resource needs.
  • Monitor resource usage regularly and adjust quotas for optimal performance.
