Redis can be accessed via port 6379 and Sentinel can be accessed via port 26379 on the following DNS name from within your cluster: redis-ha.redis-ha.svc.cluster.local

To connect to your Redis server:

1. To retrieve the redis password:

   echo $(kubectl get secret redis-ha -o "jsonpath={.data['auth']}" | base64 --decode)

2. Connect to the Redis master pod that you can use as a client. By default the redis-ha-server-0 pod is configured as the master:

   kubectl exec -it redis-ha-server-0 sh -n redis-ha

3. Connect using the Redis CLI (inside container):

   redis-cli -a <REDIS-PASS-FROM-SECRET>

Redis® can be accessed via port 6379 on the following DNS name from within your cluster:

`redis-sentinel.redis-ha.svc.cluster.local` for read only operations

For read/write operations, first access the Redis® Sentinel cluster, which is available in port 26379 using the same domain name above.

To get your password run:

    export REDIS_PASSWORD=$(kubectl get secret --namespace redis-ha redis-ha-passwd -o jsonpath="{.data.redis-password}" | base64 -d)

To connect to your Redis® server:

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

   kubectl run --namespace redis-ha redis-client --restart='Never'  --env REDIS_PASSWORD=$REDIS_PASSWORD  --image docker.io/bitnami/redis:7.0.7-debian-11-r9 --command -- sleep infinity

   Use the following command to attach to the pod:

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

2. Connect using the Redis® CLI:

   REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h redis-sentinel -p 6379 # Read only operations
   REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h redis-sentinel -p 26379 # Sentinel access

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

    kubectl port-forward --namespace redis-ha svc/redis-sentinel 6379:6379 &
    REDISCLI_AUTH="$REDIS_PASSWORD" redis-cli -h 127.0.0.1 -p 6379
