# PostgreSQL can be accessed via port 5432 on the following DNS name from within your cluster:
# {{ template "postgresql.fullname" . }}.{{ .Release.Namespace }}.svc.cluster.local

#     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) }}

# {{ if and (.Values.networkPolicy.enabled) (not .Values.networkPolicy.allowExternal) }}
