Install highly available Redis

1. Add the Bitnami repository to Helm:

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

1. 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

1. Install Redis with Helm:

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

1. 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

1. Get the Redis service name and IP address:

kubectl get service

Example output:

redis-master                                   ClusterIP   10.96.84.98     <none>        6379/TCP
