Containerize OVS/OVN Components for Easy Management
Explore how containerizing OVS/OVN components can streamline the process of managing and deploying Open vSwitch and OVN, optimizing development efforts and enabling easier movement between environments. Learn about the traditional challenges of managing OVS/OVN components and how containerization offers a more efficient solution. Discover the future support for OVN control plane as a container in cluster mode and the potential challenges and benefits it brings for production environments. Dive into Docker demos, references for container images, installation guides, and more to enhance your understanding of containerizing OVS/OVN components.

Containerize OVS/OVN components Aliasgar Ginwala (aginwala@ebay.com)
Traditional approach for managing ovs/ovn components Developers/Operators have to build and install ovs/ovn on host by downloading source, tarball, deb/rpm packages, setup VM/BM, etc. to certify and test. Automation is needed to monitor processes explicitly even for production deployment. Upgrades take time as we need to install ovs/ovn on every host in large scale environment. Cannot run in k8s with a pod spec.
Containerize ovs/ovn Easy to manage and move around Optimizes dev efforts No kernel modules required for ovn. OVN container components need not be dependent on host OS Easy to run on k8s in a pod spec by combining multiple containers in same pod.
Demo Docker Build, push and use ovs/ovn.
Future support Starting OVN control plane as a container in cluster mode. SSL support when starting containers Challenges for running it in production? Monitoring?
