Redis高可用在kubernetes中的安裝部署

• 使用helm安裝。相當簡單
• 參考 https://github.com/DandyDeveloper/charts/tree/master/charts/redis-ha

kubectl create ns redis
helm install redis-ha dandydev/redis-ha -n redis -f values.yaml
helm upgrade redis-ha dandydev/redis-ha -n redis -f values.yaml

• 以下爲values.yaml

auth: true
redisPassword: Redis@20@21

• 如果需要導出ingress。本例使用traefik

apiVersion: traefik.containo.us/v1alpha1
kind: IngressRouteTCP
metadata:
  name: redis-ha-ingressroutetcp
  namespace: redis
spec:
  entryPoints:
    - redis
  routes:
  # Match 是與基礎路由對應的規則。
  - match: HostSNI(`*`)
    services:
    - name: redis-ha
      port: 6379

• traefik需要導出entrypoints。下面只列出重要點

kind: Deployment
	...
        - name: traefik
          image: traefik:v2.4
          args:
            - --entrypoints.redis.Address=:6379
          ports:
            - name: redis
              containerPort: 6379

apiVersion: v1
kind: Service
metadata:
  name: traefik
spec:
  type: NodePort
  selector:
    app: traefik
  ports:
    - protocol: TCP
      port: 6379
      name: redis
      targetPort: 6379
      nodePort: 31002
