I have been searching alot on how to deploy redis with high availability on kubernetes. I have some problems using redis cluster mode and when using the master-slave mode we need to also deploy sentinel to be able to handle master failures

I have been reviewing this great doc which explains how to do that but, I think there is something missing.

I have deployed what's mentioned there but, I needed to make some changes to for the sentinel containers to run in sentinel mode now the main redis-master pod manifest which has the main redis master and the sentinel looks like this.

# redis-master.yaml

apiVersion: v1
kind: Pod
metadata:
  labels:
    name: redis
    redis-sentinel: "true"
    role: master
  name: redis-master
spec:
  containers:
    - name: master
      image: redis
      env:
        - name: MASTER
          value: "true"
      ports:
        - containerPort: 6379
      resources:
        limits:
          cpu: "0.1"
      volumeMounts:
        - mountPath: /redis-master-data
          name: data
    - name: sentinel
      image: redis
      command:
        - redis-sentinel
        - "/redis-master-data/redis.conf"
      env:
        - name: SENTINEL
          value: "true"
      ports:
        - containerPort: 26379
      volumeMounts:
        - mountPath: /redis-master-data
          name: data
        - mountPath: /redis-master
          name: config
  initContainers:
  - name: copy
    image: redis
    command: ["bash", "-c", "cp /redis-master/redis.conf /redis-master-data/"]
    volumeMounts:
    - mountPath: /redis-master
      name: config
    - mountPath: /redis-master-data
      name: data
  volumes:
    - name: data
      emptyDir: {}
    - name: config
      configMap:
        name: example-redis-config
        items: 
        - key: redis-config
          path: redis.conf

now after all that I am having 2 problems

• first this doc is making a service for the sentinels only so I know I should make a service for the redis but I am not even sure are they both masters or not.

• second problem assuming one is master and the other is a slave when a failure happens and the sentinel elects a new master how to make that new master belong to the service of the redis masters and not the slave service (cause usually we will make 2 services one which expose masters and the other for slaves)

NOTE: please review the doc mentioned above to understand my question well.
