SDCore Helm Charts

This repository contains Helm charts for deploying Aether SD-Core on Kubernetes.

Note that these Helm Charts can be used to deploy the Aether SD-Core. However, the user should override the values.yaml file(s) to be able to properly deploy all pods. One simple way to do so is by using the sdcore-5g-values.yaml file from Aether-Onramp. Morever, some values need to be accordingly updated depending on the specific deployment/setup as shown below.

Pre-requisites (If NOT using Aehter OnRamp)

The only pre-requisite to use the Helm Charts by themselves is the creation of the namespace for cert-manager in Kubernetes. That is, by default, the Helm Charts will try to deploy cert-manager in the namespace called cert-manager, as shown below. Therefore, the user needs to create this namespace before installing the Helm Charts.

certmanager:
  enabled: true
  fullnameOverride: certmanager
  namespace: cert-manager
  crds:
    enabled: true

Example of usage with Aether OnRamp

It is strongly recommended to use Aether-Onramp for the deployment of the SD-Core because OnRamp, besides deploying the SD-Core, it also takes care of the networking required for the packets to be forwarded across the 5GC.
