A method and system for managing dynamic runtime information provision for a container implementing a Session Management Function (SMF) executed by an electronic device in a 3rd generation partnership project (3GPP) 5th Generation (5G) mobile network core. The method includes starting a container image load, the container image including at least a secret sub unit and an application sub unit, the application sub unit providing the SMF, determining an input source to provide a secret value for the container, the input source identified by information in the secret sub unit in the container image, and providing the secret value to a destination sub unit of the container.
