创建LimitRange, memory-limit.yaml

apiVersion: v1

spec:
  limits:
  - default:
      memory: 512Mi
    defaultRequest:
      memory: 256Mi
    type: Container

命名空间上施加限制

kubectl apply memory-limit.yaml --namespace demo-ns

在该命名空间下创建pod定义，pod-limit-m-demo1.yaml

apiVersion: v1
kind: Pod
 
metadata:
  name: pod-lm-demo1
  namespace: demo-ns
  labels:
    app: pod-lm
    version: v1
 
spec:
  containers:
  - name: pod-demo1-m
    image: busybox
    ports:
    - name: demo1-m-http
      containerPort: 80
