Input Schema

Name	Required	Description
`domain`	No	Custom domain name (optional, as railway will generate one for you and is generally better to leave it up to railway to generate one. There's usually no need to specify this and there are no use cases for overriding it.)
`environmentId`	Yes	ID of the environment
`serviceId`	Yes	ID of the service
`suffix`	No	Suffix for the domain (optional, railway will generate one for you and is generally better to leave it up to railway to generate one.)
`targetPort`	No	Target port for the domain (optional, as railway will use the default port for the service and detect it automatically.)
