How scaling redis in k8s

Kubernetes
#1

I need scaling redis redis containers, and share same volumes, any ideia?
This not works, because create many volumes, one for each container: https://github.com/marcel-dempers/docker-development-youtube-series/blob/master/storage/redis/kubernetes/redis/redis-statefulset.yaml

#2

Redis nodes are not supposed to share a data volume. The nodes replicate data between themselves.
The manifest given on the github site with volumeClaimTemplate is normal for redis.
