cIPsec is a new implemented that is targeted in Frankfurt. This time, the VIMs containing these resources is no longer Openstack but Kubernetes. This implementation is planned to be achieved along with the help of the functionalities provided in Extending HPA for K8S. The K8s plugin resided in MC will handle the job of scheduling IPsec. As it is implemented in Kubernetes, IPsec need to be packaged as a helm chart that would be processed by the k8s plugin.

However, since the helm chart will be transmitted as an artifact inside the CSAR package and currently SO is not able to handle the container-based -based CSAR package, a heat template and related policies need to be mapped to the helm chart, containing the requirements that needed for IPsec.
