世界上并没有完美的程序，但是我们并不因此而沮丧，因为写程序就是一个不断追求完美的过程。

问：如何为namespace配置总的cpu和内存配额？
答：

为namespace配置总的cpu和内存配额（限制单个容器用LimitRange）

创建namespace

• kubectl create namespace quota-mem-cpu-example

创建ResourceQuota

• apiVersion: v1
  kind: ResourceQuota
  metadata:
  name: mem-cpu-demo
  spec:
  hard:
  requests.cpu: “1”
  requests.memory: 1Gi
  limits.cpu: “2”
  limits.memory: 2Gi
• kubectl create -f https://k8s.io/docs/tasks/administer-cluster/quota-mem-cpu.yaml --namespace=quota-mem-cpu-example
• kubectl get resourcequota mem-cpu-demo --namespace=quota-mem-cpu-example --output=yaml

创建Pod

• 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”
• kubectl create -f https://k8s.io/docs/tasks/administer-cluster/quota-mem-cpu-pod.yaml --namespace=quota-mem-cpu-example
• kubectl get pod quota-mem-cpu-demo --namespace=quota-mem-cpu-example
• kubectl get resourcequota mem-cpu-demo --namespace=quota-mem-cpu-example --output=yaml

删除

• kubectl delete namespace quota-mem-cpu-example
