:description: This example shows how you can create an application using multiple declarative
|
||
|
|
containers. We build an example Python micro application following the dependency
|
||
|
|
injection principle. It consists from several services with a domain logic that
|
||
|
|
have dependencies on database & AWS S3.

This example shows how you can create an application using multiple declarative containers. Using
|
||
|
|
multiple declarative containers is a good choice for a large application. For
|
||
|
|
building a moderate or a small size application refer to :ref:`application-single-container`.
