Message transmission method and device and storage medium

The invention discloses a message transmission method and device and a storage medium, relates to the technical field of communication, is applied to a working node in a container network communication system, and comprises the following steps: receiving container configuration data from a controller; and matching a container address in the container configuration data with a physical network card address of the target working node to obtain a container network segment mapping relation of the target working node, determining a traffic engineering drainage relation of the target working node according to the container network segment mapping relation of the target working node and the traffic engineering relation, and determining the traffic engineering drainage relation of the target working node according to the traffic engineering drainage relation. And transmitting the container message to the working nodes except the target working node. According to the method provided by the invention, the communication
