Dynamic container
-----------------

.. currentmodule:: dependency_injector.containers

:py:class:`DynamicContainer` is a collection of the providers defined in the runtime.

.. literalinclude:: ../../examples/containers/dynamic.py
   :language: python
   :lines: 3-

configuration file or some other source that you can reach only after application is already

.. literalinclude:: ../../examples/containers/dynamic_runtime_creation.py
