k8snamespace配置cpu最大和最小限额

世界上并没有完美的程序&＃xff0c;但是我们并不因此而沮丧&＃xff0c;因为写程序就是一个不断追求完美的过程。

问&＃xff1a;如何为namespace配置最大和最小限额&＃xff1f;
答&＃xff1a;

为namespace配置cpu最大和最小限额

创建namespace

• kubectl create namespace constraints-cpu-example

创建LimitRange

• apiVersion: v1
  kind: LimitRange
  metadata:
  name: cpu-min-max-demo-lr
  spec:
  limits:
  • max:
    cpu: “800m”
    min:
    cpu: “200m”
    type: Container
• kubectl create -f https://k8s.io/docs/tasks/administer-cluster/cpu-constraints.yaml --namespace&＃61;constraints-cpu-example
• kubectl get limitrange cpu-min-max-demo-lr --output&＃61;yaml --namespace&＃61;constraints-cpu-example

创建Pod

• apiVersion: v1
  kind: Pod
  metadata:
  name: constraints-cpu-demo
  spec:
  containers:
  • name: constraints-cpu-demo-ctr
    image: nginx
    resources:
    limits:
    cpu: “800m”
    requests:
    cpu: “500m”
• kubectl create -f https://k8s.io/docs/tasks/administer-cluster/cpu-constraints-pod.yaml --namespace&＃61;constraints-cpu-example
• kubectl get pod constraints-cpu-demo --namespace&＃61;constraints-cpu-example
• kubectl get pod constraints-cpu-demo --output&＃61;yaml --namespace&＃61;constraints-cpu-example

删除

• kubectl delete namespace constraints-cpu-example
