<!--
Specify compute resource requirements (CPU, memory) for any resource that defines a pod template. If a pod is successfully scheduled, it is guaranteed the amount of resource requested, but may burst up to its specified limits.
For each compute resource, if a limit is specified and a request is omitted, the request will default to the limit.
Possible resources include (case insensitive): Use "kubectl api-resources" for a complete list of supported resources..
-->
为定义 Pod 模板的任一资源指定计算资源要求CPU、内存
如果 Pod 被成功调度,将保证获得所请求的资源量,但可以在某一瞬间达到其指定的限制值。
对于每类计算资源,如果只指定限制值而省略请求值,则请求值将被默认设置为限制值。
可能的资源包括(不区分大小写):使用 "kubectl api-resources" 查看受支持资源的完整列表。
```shell
kubectl set resources (-f FILENAME | TYPE NAME) ([--limits=LIMITS & --requests=REQUESTS]
```
