# No CMD or Procfile in Image

### Cause

Aptible relies on your [Image's](https://www.aptible.com/docs/core-concepts/apps/deploying-apps/image/overview.md) `CMD` or the presence of a [Procfile](https://www.aptible.com/docs/how-to-guides/app-guides/define-services.md) in order to define [Services](https://www.aptible.com/docs/core-concepts/apps/deploying-apps/services.md) for your [App](https://www.aptible.com/docs/core-concepts/apps/overview.md).

If your App has neither, the deploy cannot succeed.

### Resolution

Add a `CMD` directive to your image, or add a Procfile in your repository.
