配置命名空间下 Pod 配额

创建域名空间

kubectl create namespace quota-mem-cpu-example

本地创建 yaml 文件

配置 mem-cpu 配额
复制之后在本地创建文件

apiVersion: v1
kind: ResourceQuota
metadata:
  name: mem-cpu-demo
spec:
  hard:
    requests.cpu: "1"
    requests.memory: 1Gi
    limits.cpu: "2"
    limits.memory: 2Gi

启动 ResourceQuota

kubectl apply -f ./examples/admin/resource/quota-mem-cpu.yaml --namespace=quota-mem-cpu-example

查看配额

kubectl get resourcequota pod-demo --namespace=quota-pod-example --output=yaml
spec:  
    hard:
      pods: "2"
status:
  hard:
    pods: "2"
  used:
    pods: "0"

apiVersion: v1
kind: Pod
metadata:
  name: quota-mem-cpu-demo
spec:
  containers:
  - name: quota-mem-cpu-demo-ctr
    image: nginx
    resources:
      limits:
        memory: "800Mi"
        cpu: "800m"
      requests:
        memory: "600Mi"
        cpu: "400m"

启动 Pod

kubectl apply -f ./examples/admin/resource/quota-mem-cpu-pod.yaml --namespace=quota-mem-cpu-example

kubectl get pod quota-mem-cpu-demo --namespace=quota-mem-cpu-example

apiVersion: v1
kind: Pod
metadata:
  name: quota-mem-cpu-demo-2
spec:
  containers:
  - name: quota-mem-cpu-demo-2-ctr
    image: redis
    resources:
      limits:
        memory: "1Gi"
        cpu: "800m"
      requests:
        memory: "700Mi"
        cpu: "400m"

启动

kubectl apply -f ./examples/admin/resource/quota-mem-cpu-pod-2.yaml --namespace=quota-mem-cpu-example

获取

 kubectl get pod quota-mem-cpu-demo --namespace=quota-mem-cpu-example

删除域名空间

kubectl delete namespace quota-mem-cpu-example
