NOTES:
** Please be patient while the chart is being deployed **
Redis can be accessed via port 6379 on the following DNS names from within your cluster:

bulging-eel-redis-master.default.svc.cluster.local for read/write operations
bulging-eel-redis-slave.default.svc.cluster.local for read-only operations


To get your password run:

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

To connect to your Redis server:

1. Run a Redis pod that you can use as a client:

   kubectl run --namespace default bulging-eel-redis-client --rm --tty -i --restart='Never' \
    --env REDIS_PASSWORD=$REDIS_PASSWORD \
   --image docker.io/bitnami/redis:4.0.12 -- bash

2. Connect using the Redis CLI:
   redis-cli -h bulging-eel-redis-master -a $REDIS_PASSWORD
   redis-cli -h bulging-eel-redis-slave -a $REDIS_PASSWORD

To connect to your database from outside the cluster execute the following commands:

    kubectl port-forward --namespace default svc/bulging-eel-redis 6379:6379 &
    redis-cli -h 127.0.0.1 -p 6379 -a $REDIS_PASSWORD

kubectl get pods -o wide
