io.rancher.service.external_dns_name_template Custom DNS name template that overrides global custom DNS name template (see below) of default DNS name template for a specific service

Custom DNS name template

By default DNS entries are named <service>.<stack>.<environment>.<domain>. You can specify a custom name template used to construct the subdomain part (left of the domain/zone name) of the DNS records. The following placeholders are supported:

%{{service_name}}
%{{stack_name}}
%{{environment_name}}

Example:

%{{stack_name}}-%{{service_name}}.statictext

Make sure to only use characters in static text and separators that your provider allows in DNS names.
