[大数据]k8s部署单机版redis3.0

创建本地目录用于redis持久化

创建持久化文件mkdir -p /Users/renzhengxin/IdeaProjects/k8s/redis/v30/data

创建持久卷

创建持久卷定义vim redis-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: redis30-pv
  labels:
    pv: redis30-pv
spec:
  capacity:
    storage: 20Gi
  accessModes:
  - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  hostPath:
    #此处可自定义本地已存在的路径
    path: /Users/renzhengxin/IdeaProjects/k8s/redis/v30/data

执行创建持久卷：kubectl create -f redis-pv.yaml
查看持久卷：kubectl get pv

创建持久卷声明

创建持久卷声明定义vim redis-pvc.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: redis30-pvc
spec:
  # 必须声明下面此行，否则会自动创建pv而不是绑定到已有pv
  storageClassName: ""
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi
  selector:
    matchLabels:
      pv: redis30-pv

执行创建持久卷声明：kubectl create -f redis-pvc.yaml
查看持久卷声明：kubectl get pvc
查看持久卷：kubectl get pv

创建配置文件

创建redis配置文件：vim redis-cm.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: redis30-conf
data:
  redis30.conf: |
        bind 0.0.0.0
        port 6379
        pidfile .pid
        appendonly yes
        cluster-config-file nodes-6379.conf
        pidfile /data/redis/log/redis30.pid
        cluster-config-file /data/redis/conf/redis30.conf
        dir /data/redis/data/
        logfile "/data/redis/log/redis30.log"
        cluster-node-timeout 5000

创建configMap：
kubectl create -f redis-cm.yaml
查看configMap：
kubectl describe cm redis30-conf

创建StatefulSet

创建StatefulSet定义vim redis-ss.yaml

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: redis30-app
spec:
  replicas: 1
  serviceName: redis30-svc
  selector:
    matchLabels:
      name: redis30
  template:
    metadata:
      labels:
        name: redis30
    spec:
      initContainers:
      - name: init-redis
        image: busybox:1.35
        command: ['sh', '-c', 'mkdir -p /data/redis/log/;mkdir -p /data/redis/conf/;mkdir -p /data/redis/data/']
        volumeMounts:
        - name: data
          mountPath: /data/redis/
      containers:
      - name: redis
        # 此处为M1版本的macOS使用的镜像，一般非arm架构的mac/linux使用redis:3.3即可
        image: amd64/redis:3.0
        imagePullPolicy: IfNotPresent
        command:
        - sh
        - -c
        - "exec redis-server /data/redis/conf/redis30.conf"
        ports:
        - containerPort: 6379
          name: redis
          protocol: TCP
        volumeMounts:
        - name: redis-config
          mountPath: /data/redis/conf/
        - name: data
          mountPath: /data/redis/
      volumes:
      - name: redis-config
        configMap:
          name: redis30-conf
      - name: data
        persistentVolumeClaim:
            claimName: redis30-pvc

执行创建StatefulSet：kubectl create -f redis-ss.yaml
查看StatefulSet：kubectl get statefulSet
查看Pod：kubectl get po

创建服务

创建服务定义vim redis-svc.yaml

kind: Service
apiVersion: v1
metadata:
  labels:
    name: redis30-svc
  name: redis30-svc
spec:
  type: NodePort
  ports:
  - name: redis
    port: 6379
    targetPort: 6379
    nodePort: 30030
  selector:
    name: redis30

执行创建服务：kubectl create -f redis-svc.yaml
查看服务：kubectl get svc

访问集群

如本地已安装redis客户端，使用以下命令：
redis-cli -h localhost -p 30030
查看节点信息使用以下指令：
info
