KATANA Revival and Extension

[xilouris]

There is clear objective for the Lab to continue the development and the evolution of KATANA Slice Manager. @TheReaperGR has been all over it taking his best shot in revival of KATANA to bring it up to speed with the rest components such as VIM (Latest Openstack) and Orchestrator (OSM).

Currently KATANA is operational for what essentially was the latest set of features before staying behind.

The next steps not with prioritisation are:

• Develop and integrate default support for Cloud Native Functions (CNF) exploiting current K8S support integrated in current OSM version
• Orchestrate and deploy open5GS component
• Work in monitoring and telemetry for the slices
• Integrate Blockchain support
• Security Operations support after detection of anomaly.
• etc ...

@akiskourtis @mchristopoulou we can enhance the list of features and decide on the next steps especially for support of OASEES, PRIVATEER

according to this https://osm.etsi.org/docs/user-guide/latest/05-osm-usage.html#using-kubernetes-based-vnfs-knfs

OSM expects a preinstalled K8S environment similarly to Openstack. However it can be just a cluster on another Virtualisation Host (e.g. proxmox, openstak, bare metal etc)

For OSM you can use one of these three different ways to install your Kubernetes cluster:

OSM Kubernetes cluster Network Service
Self-managed Kubernetes cluster in a VIM
Kubernetes baremetal installation

The someone can deploy available packets in K8S directly via OSM as part of extended services along with VNFs and PNFs

@OikonomakisAndreas we may need your help on this one. We need to have at least a small vanilla Proxmox based K8s in order to test this out.

NOTE: Subscription and Notification support in OSM
ETSI NFV SOL005 `defines a class of Northbound APIs through which entities can subscribe for changes in the Network Service (NS) life-cycle, Network service descriptor (NSD) and Virtual network service descriptor (VNFD). The entities get notified via HTTP REST APIs which those entities expose.

Since the current support is only restricted to NS, while NSD and VNFD are in roadmap, for here onwards we will refer subscription and notification for NS. `
