Prior to commencing execution of an application inside a working container, a temporary container having an equivalent application template or container template as the working container is started. A first instance of the application is instantiated and executed from inside the temporary container. Relevant information, obtained during the execution of the first application instance from inside the temporary container, and relevant information from a host associated with the application, is extracted. The relevant information from the host and the temporary container is aggregated. A second instance of the application is executed and the aggregated information is injected into the working container.
