在 Kubernetes 上使用 Bitnami Redis Sentinel 和 Sidekiq 可以提高可伸缩性和稳定性。

1. 部署 Bitnami Redis Sentinel

创建名为 redis-sentinel-deploy.yml 的文件，并输入以下内容：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: redis-sentinel
spec:
  replicas: 3
  selector:
    matchLabels:
      app: redis
  template:
    metadata:
      labels:
        app: redis
        role: sentinel
    spec:
      containers:
      - name: redis
        image: bitnami/redis-sentinel:latest
        args: [
          "redis-server",
          "/opt/bitnami/redis/mounted-etc/redis.conf",
          "--sentinel"
        ]
        volumeMounts:
        - name: redis-conf
          mountPath: /opt/bitnami/redis/mounted-etc/redis.conf
          subPath: redis-sentinel.conf
      volumes:
      - name: redis-conf
        configMap:
          name: redis-sentinel-config
          items:
          - key: redis-sentinel.conf
            path: redis-sentinel.conf

创建名为 redis-sentinel-svc.yml 的文件，并输入以下内容：

apiVersion: v1
kind: Service
metadata:
  name: redis-sentinel
spec:
  ports:
  - name: redis
    targetPort: 26379
    port: 26379
  selector:
    app: redis
    role: sentinel

创建名为 redis-sentinel-cm.yml 的文件，并输入以下内容：

apiVersion: v1
kind: ConfigMap
metadata:
  name: redis-sentinel-config
data:
  redis-sentinel.conf: |-
    port 26379
    daemonize no
    pidfile "/opt/bitnami/redis/var/run/redis-sentinel.pid"
    logfile "/opt/bitnami/redis/var/log/redis/redis-sentinel.log"
