namespace的配额
代码语言:txt复制cat quota.yaml
apiVersion: v1
kind: ResourceQuota
metadata:
name: object-counts
namespace: default
spec:
hard:
configmaps: "10" ## 最多10个 ConfigMap
secrets: "10" ## 最多10个 secret
services: "10" ## 最多10个 service
services.loadbalancers: "2" ## 最多2个 Loadbanlacer 模式的 service
cpu: "1000" ## 该 Namespaces 下最多使用1000个 CPU 的资源
memory: 200Gi ## 该 Namespaces 下最多使用200Gi的内存
kubectl apply -f quota.yaml
简单测试configmaps的数量限制,可以看到现在10个
代码语言:txt复制for i in {1..11};do kubectl create configmap test-config-$i --from-literal=key1=config1;done

需要部署kube-router,cni没有提供
