	// App name: Each app running on Fly.io has a unique app name. This
	// identifies the app for the user, and can also identify its Machines on
	// their IPv6 private network, using internal DNS. For example,
	// syd.$FLY_APP_NAME.internal can refer to the app’s Machines running in the
	// syd region. Read more about 6PN Naming in the Private Networking docs.
	AppName = os.Getenv("FLY_APP_NAME")

	// Machine ID: The Machine’s unique ID on the Fly.io platform. This is the

	//  Region name: The three-letter name of the region the Machine is running
	//  in. Details of current regions are listed in the Regions page. As an
	//  example, “ams” is the region name for Amsterdam.
