Requests determine how many resources a container will receive during deployment. To define how many resources will be allocated to a container, Kubernetes uses the concept of requests and limits. There are several ways to manage resource consumption in Kubernetes, which include assigning priority to pods to avoid a kernel termination when resource limits are reached, using namespaces and resource quotas, setting network policies, and configuring storage. In this article, you’ll learn more about Kubernetes CPU limits and throttling, why they are relevant, and how you can implement them.

It also helps to prevent resource hogging and out-of-memory (OOM) errors that may affect cluster health.Īdditionally, if an application exceeds its CPU limit, it’s throttled, which affects the response rate and can cause problems. Setting up these usage parameters and limits ensures you don’t exhaust resources, starve out your apps, or incur high operational costs. Kubernetes provides a number of ways to configure CPU and RAM resource usage parameters. The CPU and RAM are two of the most critical cluster resources, and they need to be specified and allocated correctly. When a pod is created on Kubernetes, you need to ensure the containers have sufficient resources to run. Resource allocation is an essential consideration when you’re running Kubernetes.
