Kubernetes HA -> Alpha CrashLoopBackOff

hi,
I tried it again,

kubectl delete pods,statefulsets,services,persistentvolumeclaims,persistentvolumes -l app=dgraph-zero
kubectl delete pods,statefulsets,services,persistentvolumeclaims,persistentvolumes -l app=dgraph-alpha
kubectl delete pods,replicasets,services,persistentvolumeclaims,persistentvolumes -l app=dgraph-ratel

copy from https://raw.githubusercontent.com/dgraph-io/dgraph/master/contrib/config/kubernetes/dgraph-ha.yaml, modify image to dgraph/dgraph:master

kubectl create dgraph_ha.ymal

and the Alpha prompt the same error message :

 ++ hostname -f
+ dgraph alpha --my=dgraph-alpha-2.dgraph-alpha.default.svc.cluster.local.:7080 --lru_mb 40960 --zero 10.68.72.53:5080
