NOTES:
** Please be patient while the chart is being deployed **

Redis(TM) can be accessed on the following DNS names from within your cluster:

    my-release-redis-master.default.svc.cluster.local for read/write operations (port 6379)
    my-release-redis-replicas.default.svc.cluster.local for read-only operations (port 6379)



To get your password run:

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

To connect to your Redis(TM) server:

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

   kubectl run --namespace default redis-client --restart='Never'  --env REDIS_PASSWORD=$REDIS_PASSWORD  --image docker.io/bitnami/redis:6.2.5-debian-10-r0 --command -- sleep infinity

   Use the following command to attach to the pod:

   kubectl exec --tty -i redis-client \
   --namespace default -- bash

2. Connect using the Redis(TM) CLI:
   redis-cli -h my-release-redis-master -a $REDIS_PASSWORD
   redis-cli -h my-release-redis-replicas -a $REDIS_PASSWORD

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

    kubectl port-forward --namespace default svc/my-release-redis-master 6379:6379 &
    redis-cli -h 127.0.0.1 -p 6379 -a $REDIS_PASSWORD
