## OVH DNS
Rancher External DNS service powered by OVH
#### Usage
##### 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.
