# Require pod resource requests and limits
|
|
|
|
Application workloads share cluster resources. Hence, it is important to manage resources assigned to each pod. It is recommended that `resources.requests.cpu`, `resources.requests.memory` and `resources.limits.memory` are configured per pod. Other resources such as GPUs may also be specified as needed.
|
|
|
|
If a namespace level request or limit is specified, defaults will automatically be applied to each pod based on the `LimitRange` configuration.
