通过Config Map来对容器中redis应用的配置进行管理，如自定义配置文件、密码、日志路径等。

创建一个namespace

接下来的pod，svc都建到这个namespace下

kubectl create namespace devops

创建redis.conf对应的ConfigMap文件

touch redis-config.yaml

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

requirepass Hangzhou@123 这个密码记住，登录的时候需要用。

更新/创建在yaml中定义的对象

kubectl apply -f redis-config.yaml  -n devops

创建持久化文件

touch redis-deploy.yaml

---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis
  labels:
    app: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
    spec:
      containers:
      - name: redis
        image: redis:3.0.7
        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

创建configmap和deployment

kubectl apply -f redis-config.yaml  --force -n devops
kubectl apply -f redis-deploy.yaml -n devops  --force

创建对外访问服务svc

touch redis-svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: redis
  namespace: devops
  labels:
    app: redis
spec:
  type: NodePort
  ports:
    - name: tcp
      port: 6379
      nodePort: 30379
  selector:
    app: redis

更新/创建在yaml中定义的对象

kubectl apply -f redis-svc.yaml -n devops

查询一下端口

kubectl get svc -n devops
