前段时间在集群上搭建了一个简易的单机版redis用于测试，注意redis是采用nodePort方式暴露的服务，因此需要在配置相应的端口安全组策略。redis编排文件如下：

apiVersion: apps/v1
kind: StatefulSet
metadata:
  labels:
    app: redis
  name: redis
  namespace: develop
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  serviceName: redis-svc
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
        - command:
            - redis-server
            - '--requirepass'
            - 'redis@654321'		# 初始密码	
          image: 'redis:5.0.5-alpine'
          imagePullPolicy: Always
          name: redis
          ports:
            - containerPort: 6379
              protocol: TCP
          resources:
            requests:
              cpu: 200m
              memory: 1Gi
          volumeMounts:
            - mountPath: /data
              name: volume-image-data
      dnsPolicy: ClusterFirst
      restartPolicy: Always
      volumes:
        - hostPath:
            path: /home/redis/develop   # 宿主机挂载路径
            type: ''
          name: volume-image-data
  updateStrategy:
    type: RollingUpdate
