# This function creates a manifest for db creation and user management.

# {- $dbToDropJob := dict "envAll" . "serviceName" "senlin" -}
# { $dbToDropJob | include "helm-toolkit.manifests.job_db_drop_mysql" }
#
# If the service does not use oslo then the db can be managed with:
# {- $dbToDrop := dict "inputType" "secret" "adminSecret" .Values.secrets.oslo_db.admin "userSecret" .Values.secrets.oslo_db.horizon -}
# {- $dbToDropJob := dict "envAll" . "serviceName" "horizon" "dbToDrop" $dbToDrop -}
