Kubernetes Resource Management: Requests, Limits, and Autoscaling

Kubernetes resource management balances performance, cost, and stability through requests, limits, and autoscaling.

#kubernetes#resources#autoscaling#devops

Kubernetes schedules workloads based on resource requirements. Proper resource configuration ensures performance while controlling costs. Autoscaling adapts to changing demands automatically.

Requests and Limits

Requests guarantee minimum resources for scheduling. Limits cap maximum resource usage. Setting these appropriately prevents starvation and runaway resource consumption.

  • Set requests based on typical resource usage
  • Configure limits preventing runaway consumption
  • Monitor actual usage adjusting configurations
  • Use LimitRange defaults for namespace standards
  • Implement ResourceQuota for namespace budgets

Autoscaling

Horizontal Pod Autoscaler scales replicas based on metrics. Vertical Pod Autoscaler adjusts resource requests. Cluster Autoscaler adds nodes when needed. Combine for comprehensive scaling.
