为什么3 3Scale需要这么多资源

Question

当我从Openshift操作符安装3 3Scale时，有人知道为什么它需要这么多资源吗？

默认安装请求4CPU和大约9Gi内存，但限制为90 9Gi。因此，除非我的项目分配了超过90 it的内存，否则它不会安装。

如果我用100个线程加载测试，我最多能得到的是2个CPU和4Gi内存，占用所有的吊舱。

这是我的API管理器yaml

apiVersion: apps.3scale.net/v1alpha1
kind: APIManager
metadata:
  annotations:
    apps.3scale.net/apimanager-threescale-version: '2.9'

这是我以后的资源使用情况

spec:
  hard:
    limits.cpu: '24'
    limits.memory: 128Gi
    requests.cpu: '6'
    requests.memory: 13743895347200m
  scopes:

status:
  hard:
    limits.cpu: '24'
    limits.memory: 128Gi
    requests.cpu: '6'
    requests.memory: 13743895347200m
  used:
    limits.cpu: 16100m
    limits.memory: 85048677Ki
    requests.cpu: 3950m
    requests.memory: '8832423808'

Answer 1

在设置这里时，您可以为每个3 3scale组件resourceRequirementsEnabled: true找到必要的计算资源。这是为生产目的部署3 3scale时所需的最低要求。如果您只部署了一个设置resourceRequirementsEnabled: false的暂存环境，那么您就可以了。

请注意，3 3scale已经在版本2.11 (2.12即将发布)

我希望这些信息对你有帮助。
