Temporary storage for files transfer between containers

There is a container with the main application. There are different types of container workers.
The main container must somewhere to put the files in some store and notify the workers. Or they have to somehow find out that a new file is the correct type for him. The worker must take this file to work with him and also send a new file to the host application.
Sometimes I need to transfer 2 or more files. Therefore it is necessary to archive them for correct transfer.
Help me, that can be used for temporary storage of files? It would be great if it is archived itself.
