1、配置configmap

kind: ConfigMap
apiVersion: v1
metadata:
  name: redis-config
  namespace: default
  labels:
    app: redis
data:
  redis.conf: |-
    dir /data
    port 6379
    bind 0.0.0.0
    appendonly yes
    protected-mode no
    requirepass 123
    pidfile /data/redis-6379.pid

2、配置nfs目录

cd /k8s
mkdir redis
chmod 777 -R redis/

2、配置pv和pvc

apiVersion: v1
kind: PersistentVolume
metadata:
  name: redis-pv
spec:
  accessModes:
    - ReadWriteOnce
  capacity:
    storage: 5Gi
  nfs:
    path: /k8s/redis
    readOnly: false
    server: 10.10.10.25  # nfs服务器ip

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: redis-pvc
  namespace: default
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 5Gi
  storageClassName: ''
  volumeName: redis-pv

3、部署deploment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  namespace: default
  labels:
    app: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
    spec:
      # 进行初始化操作，修改系统配置，解决 Redis 启动时提示的警告信息
      initContainers:
        - name: system-init
          image: busybox:1.32
          imagePullPolicy: IfNotPresent
          command:
            - "sh"
            - "-c"
            - "echo 2048 > /proc/sys/net/core/somaxconn && echo never > /sys/kernel/mm/transparent_hugepage/enabled"
          securityContext:
            privileged: true
            runAsUser: 0
          volumeMounts:
          - name: sys
            mountPath: /sys
      containers:
        - name: redis
          image: redis:5.0.8
          command:
            - "sh"
            - "-c"
            - "redis-server /usr/local/etc/redis/redis.conf"
          ports:
            - containerPort: 6379
          resources:
            limits:
              cpu: 1000m
              memory: 1024Mi
            requests:
              cpu: 1000m
              memory: 1024Mi
          livenessProbe:
            tcpSocket:
              port: 6379
            initialDelaySeconds: 300
            timeoutSeconds: 1
            periodSeconds: 10
            successThreshold: 1
            failureThreshold: 3
          readinessProbe:
            tcpSocket:
              port: 6379
            initialDelaySeconds: 5
            timeoutSeconds: 1
            periodSeconds: 10
            successThreshold: 1
            failureThreshold: 3
          volumeMounts:
            - name: data
              mountPath: /data
            - name: config
              mountPath: /usr/local/etc/redis/redis.conf
              subPath: redis.conf
      volumes:
        - name: data
          persistentVolumeClaim:
            claimName: redis-pvc
        - name: config
          configMap:
            name: redis-config
        - name: sys
          hostPath:
            path: /sys

4、配置nodeport供外部访问

apiVersion: v1
kind: Service
metadata:
  name: redis-front 
  labels:
    app: redis
  namespace: default
spec:
  selector:
    app: redis
  type: NodePort
  clusterIP: 10.43.0.2      #任意10.43.0.x
  ports:
    - name: ''
      port: 6379
      protocol: TCP
      targetPort: 6379
      nodePort: 30003      #任意30000-32767
  sessionAffinity: None
