โ˜ธ๏ธ Kubernetes YAML Resource Optimizer

Calculate and suggest optimal CPU/Memory limits and requests for Kubernetes manifests.

โ„น๏ธ About Kubernetes YAML Resource Optimizer

The Kubernetes YAML Resource Optimizer is a diagnostic tool designed to help developers and SREs fine-tune the performance of their containerized applications. Setting the right requests and limits is the most important factor in cluster stability. If limits are too low, your pods will be throttled or killed; if they are too high, you waste expensive cloud resources.

This tool uses common "bursting" ratios (2.0x for CPU and 1.5x for Memory) to generate a balanced configuration. This allows your application to handle short spikes in traffic while maintaining a predictable baseline for the Kubernetes scheduler, helping to prevent Out-Of-Memory (OOM) kills and ensuring your nodes aren't over-committed.

๐Ÿ“– How to use Kubernetes YAML Resource Optimizer

  1. 1. Determine your application's average CPU usage (e.g., 100m or 0.1).
  2. 2. Determine your average Memory usage (e.g., 128Mi or 256Mi).
  3. 3. Enter these values as the 'Requests.'
  4. 4. Click 'Run Tool' to generate the full <code>resources:</code> YAML block.
  5. 5. Copy and paste the result into your Kubernetes Deployment or Pod manifest.

โ“ Frequently Asked Questions

What is the difference between Requests and Limits?

Requests are what the Kubernetes scheduler uses to place a pod on a node. Limits are the maximum amount of resources a pod can actually consume before being throttled (CPU) or killed (Memory).

Why set the memory limit higher than the request?

Setting a limit higher than the request allows your application to 'burst' during startup or heavy loads, provided there is spare capacity on the node.

What units should I use?

For CPU, use 'm' (millicores) where 1000m = 1 CPU core. For Memory, use 'Mi' (Mebibytes) or 'Gi' (Gibibytes).
