report a bug

Describe the bug

pod stuck on container init even the temporal-cassandra is working find

temporal-admintools-6d54c4ccf-rhd5p 1/1 Running 0 8m17s temporal-cassandra-0 1/1 Running 0 8m17s temporal-frontend-8f59f594b-lqrx6 0/1 Init:1/4 0 8m17s temporal-history-7dfb5ff65-j4fjf 0/1 Init:1/4 0 8m17s temporal-matching-7fd865fbd4-xlbj6 0/1 Init:1/4 0 8m17s temporal-schema-setup-p6m5l 0/2 Init:1/4 0 8m17s temporal-web-78745cd865-bdlnt 1/1 Running 0 8m17s temporal-worker-cf5d58f6b-7cphl 0/1 Init:1/4 0 8m17s

and then i check the log on temporal-frontend

seem it resolved the k8s host machine dns and connect a external IP

so i try to dig this domain name on my own pod

temporal-cassandra.temporal.svc.cluster.local resolves to the correct address

seems k8s-dns is normal

temporal-cassandra hosts conf:

And just for reference i fixed it by change the cassandra.host to FQDN

temporal-helm/templates/_helpers.tpl: line 320

{{/* All Cassandra hosts. */}} {{- define "cassandra.hosts" -}} {{- range $i := (until (int .Values.cassandra.config.cluster_size)) }} {{- $cassandraName := include "call-nested" (list $ "cassandra" "cassandra.fullname") -}} {{- printf "%s.%s.svc.cluster.local." $cassandraName $.Release.Namespace -}} {{- end }} {{- end -}}

{{/* The first Cassandra host in the stateful set. */}} {{- define "cassandra.host" -}} {{- $cassandraName := include "call-nested" (list . "cassandra" "cassandra.fullname") -}} {{- printf "%s.%s.svc.cluster.local." $cassandraName .Release.Namespace -}} {{- end -}}

but i m not sure the reason

pls help to check and confirm
