This was an overview of the things that we're woking on ONAP to make possible the execution of VNFs in Kubernetes

1. Support of Containerized
Workloads in ONAP

2. Provides a comprehensive platform for real-time, policy-driven orchestration and
automation of physical and virtual network functions that will enable software,
network, IT and cloud providers and developers to rapidly automate new services and
support complete lifecycle management.

4. Current status
• Supports OpenStack based remote
• Windriver Titanium
• VMWare VIO
• Native Kilo, Newton, Ocata,
Pike…
• Only VM based VNFs.

5. Proposal
• Support for containerized VNFs or CNFs.
• Kubernetes can be used for both VMs
and Containers
• Avoid multiple controllers.
• Reduce number of compute nodes.

8. MultiCloud/k8s plugin
Phase 1 :
- Come out Multi-Service changes
- Test with VMs and containers.
- Test using scripts on top of Multi-Cloud Service(simulating SO
actions)
- Identify TOSCA modeling changes.
- Provide feedback to bigger architecture to support K8S.
- Testing
- DP Container: DPDK based Router
- IOT infrastructure: EdgeX services as containers
- Ensure that both VM and containers can exist on same
networks.
Model Driven API:
- TOSCA fragments in API
- API categories : Compute, Storage and Networks.
K8S Plugin (Go lang)
- Converts TOSCA to K8S API data.
- Converts TOSCA VL fragment to OVN API
- Uses OPNFV TOSCA parser (Python Service – Modifications are
needed)
Edge :
- Virtlet for VMs, Dockers for Containers.
- OVN for networking

11. How to contribute it?
1. Using the Kubernetes Reference Deployment (KRD) to setup an environment
• https://git.onap.org/multicloud/k8s/tree/vagrant/README.md
2. Attend weekly meetings
• https://wiki.onap.org/pages/viewpage.action?pageId=16009184
3. Do code reviews and submit patches:
• https://gerrit.onap.org/r/#/q/project:multicloud/k8s
4. Improve the documentation
