Proxmox VE and Kubernetes Network

[debtolee]

H i
I created two Proxmox VE environments. And I installed Kubernetes to create master 3 worker 6.
Then I installed bitnami/postgresql-ha with replica 6 using helm.

helm install postgresql-ha -n ${nsc} db-postgres/postgresql-ha -f db-postgres/postgresql-ha/values.yaml \
  --set postgresql.password=MyPassword \
  --set postgresql.repmgrPassword=MyPassword \
  --set pgpool.adminPassword=MyPassword \
  --set postgresql.pgHbaTrustAll=true \
  --set postgresql.maxConnections=900 \
  --set postgresql.replicaCount=6 \
  --set postgresql.usePgRewind=true \
  --set postgresql.extendedConf="wal_log_hints = on" \
  --set postgresql.image.debug=true \
  --set volumePermissions.enabled=true \
  --set pgpool.image.debug=true \
  --set metrics.image.debug=true \
  --set backup.enabled=true \
  --set backup.cronjob.storage.existingClaim="nfs-db-postgres-ha-backup" \
  --set backup.cronjob.storage.size=4Gi \
  --set service.type=NodePort \
  --set service.nodePorts.postgresql=MyPort
  # --set postgresql.upgradeRepmgrExtension=true

helm upgrade  postgresql-ha -n ${nsc} db-postgres/postgresql-ha -f db-postgres/postgresql-ha/values.yaml \
  --set postgresql.password=MyPassword \
  --set postgresql.repmgrPassword=MyPassword \
  --set pgpool.adminPassword=MyPassword \
  --set postgresql.pgHbaTrustAll=true \
  --set postgresql.maxConnections=900 \
  --set postgresql.replicaCount=6 \
  --set postgresql.usePgRewind=true \
  --set postgresql.extendedConf="wal_log_hints = on" \
  --set postgresql.image.debug=true \
  --set volumePermissions.enabled=true \
  --set pgpool.image.debug=true \
  --set metrics.image.debug=true \
  --set backup.enabled=true \
  --set backup.cronjob.storage.existingClaim="nfs-db-postgres-ha-backup" \
  --set backup.cronjob.storage.size=4Gi \
  --set service.type=NodePort \
  --set service.nodePorts.postgresql=MyPort \
  --set postgresql.upgradeRepmgrExtension=true

But only one pod works and the rest goes to 0/1 Running state.

It worked without any problems when configured with nodes in a single pc, but this time, when I tried to install postgresql after configuring Kubernetes master node 3 and workernode 6 in two nodes of the proxmox ve environment, respectively, this issue arose.

I don't know what I'm gonna do.
