# PostgreSQL can be accessed via port 5432 on the following DNS name from within your cluster:
# {{ template "postgresql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local
# 
# To get your user password run:
# 
#     PGPASSWORD=$(kubectl get secret --namespace {{ .Values.global.nsPrefix }} {{ template "postgresql.fullname" . }} -o jsonpath="{.data.postgres-password}" | base64 --decode; echo)
# 
# To connect to your database run the following command (using the env variable from above):
# 
#    kubectl run --namespace {{ .Values.global.nsPrefix }} {{ template "postgresql.fullname" . }}-client --restart=Never --rm --tty -i --image postgres \
#    --env "PGPASSWORD=$PGPASSWORD" \{{- if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
#    --labels="{{ template "postgresql.fullname" . }}-client=true" \{{- end }}
#    --command -- psql -U {{ default "postgres" .Values.postgresUser }} \
#    -h {{ template "postgresql.fullname" . }} {{ default "postgres" .Values.postgresDatabase }}
# 
# {{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
# Note: Since NetworkPolicy is enabled, only pods with label
# {{ template "postgresql.fullname" . }}-client=true"
# will be able to connect to this PostgreSQL cluster.
# {{- end }}
# 
# To connect to your database directly from outside the K8s cluster:
#    {{- if contains "NodePort" .Values.service.type }}
#      PGHOST=$(kubectl get nodes --namespace {{ .Values.global.nsPrefix }} -o jsonpath='{.items[0].status.addresses[0].address}')

#      PGHOST=127.0.0.1
#      PGPORT={{ default "5432" .Values.service.port }}
# 
#      # Execute the following commands to route the connection:
#      export POD_NAME=$(kubectl get pods --namespace {{ .Values.global.nsPrefix }} -l "app={{ template "postgresql.fullname" . }}" -o jsonpath="{.items[0].metadata.name}")
#      kubectl port-forward --namespace {{ .Values.global.nsPrefix }} $POD_NAME {{ default "5432" .Values.service.port }}:{{ default "5432" .Values.service.port }}
