一、创建ConfigMap

（1）首先创建命名空间

kubectl create namespace ospp

（2）编写redis-config.yaml文件，内容如下：

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

（3）使用如下命令创建configmap

[root@master ospp]# kubectl apply -f redis-config.yaml
configmap/redis-config created
[root@master ospp]#

二、创建Redis

（1）编写redis.yaml文件，内容如下：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  namespace: ospp
  labels:
    app: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
      - name: redis
        image: redis:5.0.7
        command:
          - "sh"
          - "-c"
          - "redis-server /usr/local/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: config
          mountPath:  /usr/local/redis/redis.conf
          subPath: redis.conf
      volumes:
      - name: config
        configMap:
          name: redis-config
---
apiVersion: v1
kind: Service
metadata:
  name: service-redis
  namespace: ospp
spec:
  ports:
    - port: 6379
      protocol: TCP
      targetPort: 6379
      nodePort: 30120
  selector:
    app: redis
  type: NodePort

（2）使用如下命令创建redis

[root@master ospp]# kubectl apply -f redis.yaml
deployment.apps/redis created
service/service-redis unchanged
[root@master ospp]#

（3）查看创建资源如下：

[root@master ospp]# kubectl get service,deploy,pod -n ospp -o wide
NAME                    TYPE       CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE    SELECTOR
service/service-redis   NodePort   10.100.68.76   <none>        6379:30120/TCP   2m8s   app=redis
NAME                    READY   UP-TO-DATE   AVAILABLE   AGE   CONTAINERS   IMAGES        SELECTOR
deployment.apps/redis   1/1     1            1           36s   redis        redis:5.0.7   app=redis
NAME                         READY   STATUS    RESTARTS   AGE   IP             NODE    NOMINATED NODE   READINESS GATES
pod/redis-748df49b99-kdhx5   1/1     Running   0          36s   10.244.2.146   node2   <none>           <none>
[root@master ospp]#

三、验证redis

（1）若为安装redis-cli，先安装redis-cli

wget http://download.redis.io/redis-stable.tar.gz
tar -zxvf redis-stable.tar.gz
mv redis-stable /usr/local/src/
cd /usr/local/src
cd redis-stable/
 make redis-cli
cp src/redis-cli /usr/local/bin/

（2）然后链接redis，如下表示OK

[root@master redis-stable]# redis-cli -h 192.168.16.40 -p 30120
192.168.16.40:30120> keys *
(error) NOAUTH Authentication required.
192.168.16.40:30120> auth test
OK
192.168.16.40:30120> exit
[root@master redis-stable]#
