+## DigitalOcean DNS
+
+Rancher External DNS service powered by DigitalOcean
+
+#### Changelog
+
+##### v0.6.4
+
+* Adds support for overriding name template for specific services by setting io.rancher.service.external_dns_name_template label to it in docker-compose.yml
+
+#### Usage
+
+##### DigitalOcean DNS record TTL
+The DigitalOcean API currently does not support per-record TTL setting. You should configure the global TTL setting for the domain manually and set it to a low value (e.g. 60).
+
+##### Limitation when running the service on multiple Rancher servers
+
+When running multiple instances of the External DNS service configured to use the same domain name, then only one of them can run in the "Default" environment of a Rancher server instance.
+
+##### Supported host labels
+
+`io.rancher.host.external_dns_ip`     
+Override the IP address used in DNS records for containers running on the host. Defaults to the IP address the host is registered with in Rancher.
+      
+`io.rancher.host.external_dns`    
+Accepts 'true' (default) or 'false'    
+When this is set to 'false' no DNS records will ever be created for containers running on this host.
+
+##### Supported service labels
+
+`io.rancher.service.external_dns`     
+Accepts 'always', 'never' or 'auto' (default)  
+- `always`: Always create DNS records for this service
+- `never`: Never create DNS records for this service
+- `auto`: Create DNS records for this service if it exposes ports on the host
+
+`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.
