The application specification, or app spec, is a YAML manifest that declaratively states everything App Platform knows about your app. Each resource in your app is represented with all of its configuration values. App Specs are useful for automating App Platform operations; both the
doctl command-line tool and the DigitalOcean API allow you to upload App Specs for both the creation of new apps, and the editing of existing apps.
To download the App Spec for your app, go to the Settings tab for your app, and click the View link.
