Some subsystems of OpenSDN solution are delivered as Docker containers.

OpenSDN Containers

The following are key features of the new architecture of OpenSDN containers:

  • All of the OpenSDN containers are multiprocess Docker containers.

  • Each container has an INI-based configuration file that has the configurations for all of the applications running in that container.

  • Each container is self-contained, with minimal external orchestration needs.

  • A single tool, Ansible, is used for all levels of building, deploying, and provisioning the containers. The Ansible code for the OpenSDN system is named tf-ansible and kept in a separate repository. The OpenSDN Ansible code is responsible for all aspects of OpenSDN container build, deployment, and basic container orchestration.
