Integrate SD-Core with an Externally Managed Radio

For simplicity in managing deployments, the gNB Name can be supplied via a charm integration. This is the purpose of the sdcore-gnb-integrator charm.

Pre-requisites

• A Kubernetes cluster capable of handling the load from a container per represented gNB

• Charmed Aether SD-Core Terraform modules Git repository cloned onto the Juju host machine

• Charmed Aether SD-Core already deployed using Terraform

You need to have the following information ready:

• A name for the gNB

• The name of the juju model for the gNB integrator

• The name of the control plane model

• An offer URL from the core for the fiveg_core_gnb interface

Deploying gNB Integrator

Given the following:

• Model name: gnb-integration

• GNB Name: gnb01

• Control Plane Model: control-plane

• Offer URL: juju_offer.nms-fiveg-core-gnb.url

Either create a new .tf file, or add the following content to you existing main.tf.

module "gnb01" {
  app_name   = "gnb01"
  source     = "git::https://github.com/canonical/sdcore-gnb-integrator//terraform?ref=v1.5"
  model_name = "gnb-integration"
  channel    = "1.5/stable"
}

resource "juju_integration" "nms-gnb01" {
  model = "control-plane"

  application {
    name     = module.gnb01.app_name
    endpoint = module.gnb01.requires.fiveg_core_gnb
  }

  application {
    offer_url = juju_offer.nms-fiveg-core-gnb.url
  }
}
