Kubermetes 部署redis pod

Redis PersistentVolume 定义 (redis-pv.yaml)

apiVersion: v1
kind: PersistentVolume
metadata:
  name: redis-pv-volume
spec:
  capacity:
    storage: 1Gi # 确保与PVC请求的大小一致
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  hostPath:
    path: "/mnt/data" # 根据实际环境调整路径。注意：hostPath仅适用于单节点测试环境。

Redis PersistentVolumeClaim 定义 (redis-pvc.yaml)

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: redis-pv-claim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi # 根据需求调整大小
  storageClassName: "" # 如果有特定的StorageClass，请填写相应的名称，否则留空使用默认

Redis Deployment 和 Service 定义 (redis-deployment.yaml)

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis-deployment
spec:
  selector:
    matchLabels:
      app: redis
  replicas: 1
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
        - name: redis
          image: redis:latest
          ports:
            - containerPort: 6379
          env:
            - name: REDIS_PASSWORD # 设置环境变量
              value: "Ql250205" # 替换为你想要的密码
          args: ["--requirepass", "$(REDIS_PASSWORD)", "--bind", "0.0.0.0"] # 允许所有IP访问并设置密码
          volumeMounts:
            - name: redis-persistent-storage
              mountPath: /data
      volumes:
        - name: redis-persistent-storage
          persistentVolumeClaim:
            claimName: redis-pv-claim
---
apiVersion: v1
kind: Service
metadata:
  name: redis-service
spec:
  ports:
    - port: 6379
      targetPort: 6379
      nodePort: 31002 # 选择一个未被占用的NodePort
  selector:
    app: redis
  type: NodePort

应用这些配置

创建 PersistentVolume：

kubectl apply -f redis-pv.yaml

创建 PersistentVolumeClaim：

kubectl apply -f redis-pvc.yaml

部署 Redis 并创建服务：

kubectl apply -f redis-deployment.yaml

检查 Redis Pod 和 Service 是否正常运行：

kubectl get pods
kubectl get svc
