# helm install redis redis
NAME: redis
LAST DEPLOYED: Wed Jul  8 14:00:29 2020
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Redis can be accessed via port 6379 on the following DNS name from within your cluster:
redis-redis.default.svc.cluster.local
To get your password run:

    REDIS_PASSWORD=$(kubectl get secret --namespace default redis-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 redis-redis-client --rm --tty -i \
    --env REDIS_PASSWORD=$REDIS_PASSWORD \
   --image bitnami/redis:4.0.8-r2 -- bash

2. Connect using the Redis CLI:

  redis-cli -h redis-redis -a $REDIS_PASSWORD
