This is also called the folder format. - **Single-file format**: Defined by a data from the previously three files concatenated in the order givem and separated by `---\n` in a single file named named 'my-app.dockerapp'. -- **Image forma t**: Defined by a Docker image in the engine store or exported as a tarball. +- **Image format**: Defined by a Docker image in the engine store or exported as a tarball. The docker-app binary lets a user render an application package to a Compose file using the settings values in the settings file or those specified by the user. This Compose file can then be deployed to a cluster running in Swarm mode or Kubernetes using `docker stack deploy` or to a single engine or Swarm classic cluster using `docker-compose up`.
