Docker needs network only when one uses Dockerfile for deployment, a rather bad idea. Instead Docker images should be used. It allows to verify them on development/testing machine before deployment. And with this setup all "bad pieces" of Docker are located at developer's notebook. In production everything is read-only and shared among all containers.
