Install highly available Redis

1. Add the Bitnami repository to Helm:

   helm repo add bitnami https://charts.bitnami.com/bitnami
   

2. Create a custom values file named redis-values.yaml and add the following configuration:

   master:
     persistence:
       enabled: true
       size: 8Gi
       storageClass: "<nameofstorageclass>"
     resources:
       requests:
         memory: 256Mi
         cpu: 100m
       limits:
         memory: 512Mi
         cpu: 200m
   replica:
     replicaCount: 3
     persistence:
       enabled: true
       size: 8Gi
       storageClass: "<nameofstorageclass>"
     resources:
       requests:
         memory: 256Mi
         cpu: 100m
       limits:
         memory: 512Mi
         cpu: 200m
   

3. Install Redis with Helm:

   helm install redis bitnami/redis -f redis-values.yaml
   

4. Save the Redis password as an environment variable:

   export REDIS_PASSWORD=$(kubectl get secret --namespace default redis -o jsonpath="{.data.redis-password}" | base64 -d)
   echo $REDIS_PASSWORD
   

5. Get the Redis service name and IP address:

   kubectl get service
   

   Example output:

   redis-master                                   ClusterIP   10.96.84.98     <none>        6379/TCP
