zeros are working but alphas are not

When running helm install, alphas have following invalid address errors:

2020/03/24 13:21:01 dgraph3-dgraph-alpha-2.dgraph3-dgraph-alpha-headless.default.svc.cluster.local.:7080 is not valid address

runtime.goexit
	/usr/local/go/src/runtime/asm_amd64.s:1357

But everything are fine in zeros. Is that anything wrong when checking --my parameter for alpha?

to bypass the --my parameter checking, I changed alpha-statefulset.yaml as below, now the problem is fixed.

<             [[ `hostname` =~ -([0-9]+)$ ]] || exit 1
<             idx=${BASH_REMATCH[1]}
<             dgraph alpha --my={{ template "dgraph.alpha.fullname" . }}-$idx.{{ template "dgraph.alpha.fullname" . }}-headless.${POD_NAMESPACE}.svc.cluster.local:7080 --lru_mb {{ .Values.alpha.lru_mb }} --zero {{ template "dgraph.zero.fullname" . }}-0.{{ template "dgraph.zero.fullname" . }}-headless.${POD_NAMESPACE}.svc.cluster.local:5080

if it still has problem, replace with ip (hostname -i) should work:

dgraph alpha --my=$(hostname -i):7080 --lru_mb {{ .Values.alpha.lru_mb }} --zero {{ template "dgraph.zero.fullname" . }}-0.{{ template "dgraph.zero.fullname" . }}-headless.${POD_NAMESPACE}.svc.cluster.local:5080
