k8s搭建redis单机版

1、创建redis配置configmaps
创建namespace
kubectl create namespace plugins

namespace/dev created

创建StatefulSet，并把数据挂载到宿主机上
vim statefulset-redis.yaml

---
apiVersion: v1
kind: ConfigMap
metadata:
  name: redis-conf
data:
  redis.conf: |
    bind 0.0.0.0
    port 6379
    requirepass 1qaz2wsx.
    pidfile .pid
    appendonly yes
    cluster-config-file nodes-6379.conf
    pidfile /data/k8s/mnt/redis/log/redis-6379.pid
    cluster-config-file /data/k8s/mnt/redis/conf/redis.conf
    dir /data/k8s/mnt/redis/data/
    logfile "/data/k8s/mnt/redis/log/redis-6379.log"
    cluster-node-timeout 5000
    protected-mode no

          volumeMounts:
            - name: data
              mountPath: /data/k8s/mnt/redis/
      containers:

          image: redis:5.0.8
          imagePullPolicy: IfNotPresent
          command:
            - sh
            - -c
            - "exec redis-server /data/k8s/mnt/redis/conf/redis.conf"
          ports:
            - containerPort: 6379
              name: redis
              protocol: TCP
          volumeMounts:
            - name: redis-config
              mountPath: /data/k8s/mnt/redis/conf/
            - name: data
              mountPath: /data/k8s/mnt/redis/
      volumes:
        - name: redis-config
          configMap:
            name: redis-conf
        - name: data
          hostPath:
            path: /data/k8s/mnt/redis/

部署
kubectl create -f redis-service.yaml -n plugins

3、连接测试
