Kubernetes----部署单节点Redis

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: v1kind: ConfigMapmetadata: name: redis-config namespace: ospp labels: app: redisdata: 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.yamlconfigmap/redis-config created[root@master ospp]#

二、创建Redis

（1）编写redis.yaml文件，内容如下：

apiVersion: apps/v1kind: Deploymentmetadata: name: redis namespace: ospp labels: app: redisspec: 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: v1kind: Servicemetadata: name: service-redis namespace: osppspec: ports: - port: 6379 protocol: TCP targetPort: 6379 nodePort: 30120 selector: app: redis type:

（2）使用如下命令创建redis

[root@master ospp]# kubectl apply -f redis.yamldeployment.apps/redis createdservice/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 wideNAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE SELECTORservice/service-redis NodePort 10.100.68.76 6379:30120/TCP 2m8s app=redisNAME READY UP-TO-DATE AVAILABLE AGE CONTAINERS IMAGES SELECTORdeployment.apps/redis 1/1 1 1 36s redis redis:5.0.7 app=redisNAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATESpod/redis-748df49b99-kdhx5 1/1 Running 0 36s 10.244.2.146 node2 [root@master ospp]#

三、验证redis

（1）若为安装redis-cli，先安装redis-cli

wget -zxvf redis-stable.tar.gzmv redis-stable /usr/local/src/cd /usr/local/srccd redis-stable/ make redis-clicp

（2）然后链接redis，如下表示OK

[root@master redis-stable]# redis-cli -h 192.168.16.40 -p 30120192.168.16.40:30120> keys *(error) NOAUTH Authentication required.192.168.16.40:30120> auth testOK192.168.16.40:30120> exit[root@master redis-stable]#
