Question

使用以下命令在本地集群kubernetes上运行e2e测试：

<style type="text/css" media="print">
  @page {
    size: auto;  
    margin: 0;  
  }
</style>
//now set manual padding to body
<style>
  body{
    padding-left: 1.3cm;
    padding-right: 1.3cm; 
    padding-top: 1.1cm;
  }
</style>

显示错误：

go run hack/e2e.go -- --provider=local --test --check-version-skew=false --test_args="--host=https://192.168.1.5:6443 --ginkgo.focus=\[Feature:Performance\]"

貌似，本地集群Kubernetes具有每个节点Pod的限制。如何解决这个问题？本地群集配置为：

[Feature:Performance] should allow starting 30 pods per node using { ReplicationController} with 0 secrets, 0 configmaps and 0 daemons [BeforeEach]

Answer 1

根据kubelet documentation：

--max-pods int32
Number of Pods that can run on this Kubelet. (default 110)

因此，110应该足以通过测试。但是测试可能会根据Allocatable.CPU and Allocatable.Memory

来衡量节点的实际容量

此外，在测试运行之前，所有名称空间都应为deleted：

// Terminating a namespace (deleting the remaining objects from it - which
// generally means events) can affect the current run. Thus we wait for all
// terminating namespace to be finally deleted before starting this test.

您的名称空间之一似乎仍处于活动状态，因此测试失败。

应该允许每个节点启动30个Pod
