有没有办法为kubernetes上的redis设置maxmemory和maxmemory策略？
我正在使用命令kubectl apply-f redis-cache.yaml
文件redis-cache.yaml包含以下内容：

apiVersion: apps/v1
data:
  redis-config: |
    maxmemory 256
    maxmemory-policy allkeys-lru
kind: Deployment
metadata:
  name: redis-cache
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis-cache
  template:
    metadata:
      labels:
        app: redis-cache
    spec:
      nodeSelector:
        "beta.kubernetes.io/os": linux
      containers:
      - name: redis-cache
        image: redis
        resources:
          requests:
            cpu: 100m
            memory: 128Mi
          limits:
            cpu: 150m
            memory: 256Mi
        ports:
        - containerPort: 6379
          name: redis
---
apiVersion: v1
kind: Service
metadata:
  name: redis-cache
spec:
  ports:
  - port: 6379
  selector:
    app: redis-cache

库伯内特家族 deployment 没有名为 data .
您可以通过 ConfigMap 或者 Secret . redis配置文件位于 installdir/redis/etc/redis.conf .
配置Map：

apiVersion: v1
kind: ConfigMap
metadata:
  name: redis-config
data:
  redis.conf: |-
    maxmemory 256
    maxmemory-policy allkeys-lru

部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis-cache
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis-cache
  template:
    metadata:
      labels:
        app: redis-cache
    spec:
      nodeSelector:
        "beta.kubernetes.io/os": linux
      volumes:
      - name: redis-config
        configMap:
          name: redis-config
      containers:
      - name: redis-cache
        image: redis
        volumeMounts:
        - name: redis-config
          mountPath: /redis/etc
        resources:
          requests:
            cpu: 100m
            memory: 128Mi
          limits:
            cpu: 150m
            memory: 256Mi
        ports:
        - containerPort: 6379
          name: redis
