Introduction / Background:

As part of the 5G slicing use case, the core NSSMF shall be instantiating a 5G core service which typically would comprise of AMF, SMF and UPF CNFs.

In order to demonstrate this use case a dummy AMF, SMF and UPF helm charts are created. The configurations applied to these CNFs during instantiation and later as part of day 2 configurations comprise of S-NSSAI and the configuration mechanism is assumed to be configmap type of k8s. 

This page provides all the details on how to design a typical 5G core NS in SDC, Helm charts for dummy AMF, SMF, UPF and CBA packages for day 0, day 1 and day 2 configurations. These artifacts could form as a base template / seed artifacts using which interested people could try onboarding the vendor 5G core CNFs.

As part of the 

5G Core Slice creation and Core NS instantiation using the Macro flow through NBI Automation.
Here we are performing the Instantiation,Day0,Day1 and Day2 configuration with help of SO, SDNC, Multicloud (k8s-plugin) and CDS.
There are two E2E workflows involved i.e Macro POST (Instantiation) and PUT (Modify Config) operations.

Prerequisites:

  • Update the SO catalogdb table as below for config-assign and config-deploy process from SO to CDS
  • Update the CBA package with VF name, i.e we need to create the "snssai" property at VF level (ex: VF name "fiveg" and property is "snssai"), so it will look in Service as "fiveg0_snssai".
