The default domain

Ferry serves a service under each domain of the server, but shows its URL with one domain.

The default domain sets the URL of a service in three places.

Place	What uses the default domain
The dashboard	The URL of each service
The CLI	The command `ferry open`
Your app	The variable `FERRY_EXTERNAL_URL`

Change the default domain

Terminal

$ ferry domains default example.comexample.com is the default domain: services are shown at https://<service>.example.com

Only a domain that Ferry serves can be the default.
A service reads its new FERRY_EXTERNAL_URL at its next deploy or restart.
If the default was a local name such as localhost, the first domain that becomes active becomes the default.
If you disconnect the default domain, the base domain becomes the default again.

Statuses of a domain

The status tells you if the names under a domain reach the server.

Manage domains

List the domains of the server, test one, change the default, or disconnect one.
