应允许每个节点启动30个pods

Question

在本地群集kubernetes上运行e2e-test，命令如下：

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

显示错误：

[Feature:Performance] should allow starting 30 pods per node using { ReplicationController} with 0 secrets, 0 configmaps and 0 daemons [BeforeEach]
• Failure in Spec Setup (BeforeEach) [6.331 seconds]

看起来，本地集群Kubernetes有每个节点的pod限制。如何解决这个问题？本地集群配置为：

leeivan@master01:~/gowork/src/k8s.io/kubernetes$ kubectl get nodes
