Resource management is a cornerstone of effective Kubernetes operations. To ensure that applications within a Kubernetes cluster receive the resources they need while preventing resource exhaustion, Kubernetes provides a mechanism known as requests and limits. These settings define the minimum (requests) and maximum (limits) amount of CPU and memory that a Pod is allowed to consume. By carefully setting these values, administrators can optimize resource utilization, prevent resource contention, and enhance overall cluster stability. This article delves into the concepts of requests and limits, providing practical examples and best practices for their implementation.
