Name

The name is the unique identifier of the application. Platform.sh supports multiple applications within a project, so each application must have a unique name within a project. The name may only be composed of lower case alpha-numeric characters (a-z0-9).

Warning:

Changing the name of your application after it has been deployed will destroy all storage volumes and result in the loss of all persistent data. This is typically a Very Bad Thing to do. It could be useful under certain circumstances in the early stages of development but you almost certainly don’t want to change it on a live project.

This name is used in the .platform/routes.yaml file to define the HTTP upstream (by default php:http). For instance, if you called your application app you will need to use app:http in the upstream field.

You can also use this name in multi-application relationships.
