Create clusters manually

kubectl -n test01 exec -it redis-0 -- redis-cli --cluster create --cluster-replicas 1 $(kubectl -n test01 get pods -l app=redis -o jsonpath='{range.items[*]}{.status.podIP}:6379 ' | awk 'NF--')

Automatically create clusters

helm repo add bitnami https://charts.bitnami.com/bitnami
helm install staging bitnami/redis-cluster \
  --set usePassword=false \
  --set replica.replicaCount=6 \
  --set persistence.size=1Gi \
  --set metrics.enabled=true \
  --set persistence.storageClass=openebs-hostpath

# Turn on  metrics Will turn on the side car
