Kubernetes Pod 资源限制

官方文档：https://kubernetes.io/docs/concepts/configuration/manage-compute-resources-container/

Pod和Container的资源请求和限制：
• spec.containers[].resources.limits.cpu
• spec.containers[].resources.limits.memory
• spec.containers[].resources.requests.cpu
• spec.containers[].resources.requests.memory

1、创建测试实例
vim pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: frontend
spec:
  containers:
  - name: db
    image: mysql
    env:
    - name: MYSQL_ROOT_PASSWORD
      value: "password"
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"
  - name: wp
    image: wordpress
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"

2、查看pod创建实例

NAME                              READY   STATUS    RESTARTS   AGE
frontend                          2/2     Running   1          63s

kubectl get pods
