Abstract: Embodiments for aggregated information calculation and injection for application containers by one or more processors. 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.

Abstract: Embodiments for applying host access control rules for application containers by one or more processors. A first set of user identifiers and permissions is extracted from a temporary container and a second set of user identifiers and permissions is extracted from a host on which a working container will reside. The first set and the second set of user identifiers and permissions are combined into an aggregate set of user identifiers and permissions and injected into the working container.

Abstract: Embodiments for aggregated information calculation and injection for application containers by one or more processors. 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. Relevant information from inside the temporary container and relevant information from a host associated with the application is extracted. Aggregated information is calculated based on the extracted relevant information from inside the temporary container and from the host.

Abstract: Caching extracted information from application containers by one or more processors. Upon extracting relevant information from a temporary container, the relevant information is cached at a container template level. A space guard is applied controlling an amount of storage consumed by the cached relevant information, and a time guard is applied controlling an expiration of the cached relevant information. The cached relevant information is maintained for injection into a working container. Applying the space guard includes defining a purge process for pruning or removing cached relevant information stored in the cache, and candidate files for the purge process may be identified using a predetermined criterion. Applying the time guard includes using a time metric defined in a profile of an information injection agent, where the time metric is based on one of a creation time, a last access time or a last modified time of the cached relevant information.
