+** 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:
+redis-master.default.svc.cluster.local for read/write operations
+redis-slave.default.svc.cluster.local for read-only operations
+To get your password run:
+    export REDIS_PASSWORD=$(kubectl get secret --namespace default redis -o jsonpath="{.data.redis-password}" | base64 --decode)
+To connect to your Redis server:
+. Run a Redis pod that you can use as a client:
+   kubectl run --namespace default redis-client --rm --tty -i --restart='Never' \
+    --env REDIS_PASSWORD=$REDIS_PASSWORD \
+   --image docker.io/bitnami/redis:6.0.3-debian-10-r2 -- bash
+. Connect using the Redis CLI:
+   redis-cli -h redis-master -a $REDIS_PASSWORD
+   redis-cli -h redis-slave -a $REDIS_PASSWORD
+To connect to your database from outside the cluster execute the following commands:
+    kubectl port-forward --namespace default svc/redis-master 6379:6379 &
+    redis-cli -h 127.0.0.1 -p 6379 -a $REDIS_PASSWORD
