Installing 5G core in an Oracle Cloud Kubernetes cluster enhanced with Verrazzano

Create a namespace:

kubectl create namespace open5gs

Enable Istio sidecar injection in ns using Rancher UI:

Or using kubectl:

kubectl label namespace open5gs istio-injection=enabled 

Now execute the following:

kubens open5gs

helm repo add openverso https://gradiant.github.io/openverso-charts/

helm install open5gs openverso/open5gs --version 2.0.8 --values https://gradiant.github.io/openverso-charts/docs/open5gs-ueransim-gnb/5gSA-values.yaml 

Wait for the stuff to be created:

Let’s see if we can open up the webui, execute the following:

kubectl port-forward svc/open5gs-webui 3000:3000

And open localhost:3000 in you browser (admin/1423):

Webui shows the 2 subscribers created on deployment:

Now open Kiali and take a look to the graph, the 5g network functions are comunicating with the network repository.

Now, let’s continue deploying the RAN emulation:

helm install ueransim-gnb openverso/ueransim-gnb --version 0.2.2 --values https://gradiant.github.io/openverso-charts/docs/open5gs-ueransim-gnb/gnb-ues-values.yaml

ueransim-gnb successfully installed!
Check gnodeb log with:

kubectl -n open5gs1 logs deployment/ueransim-gnb


You have also deployed 2 ues. You can enter ues terminal with:

kubectl -n open5gs1 exec -ti deployment/ueransim-gnb-ues -- /bin/bash

There is a tun interface for each ue. 
You can bind your application to the interface to test ue connectivity.
Example:

ping -I uesimtun0 gradiant.org
traceroute -i uesimtun0 gradiant.org
curl --interface uesimtun0 https://www.gradiant.org/ 


You can also deploy more ues connected to this gnodeb with openverso/ueransim-ues chart:

helm install -n open5gs1 ueransim-ues openverso/ueransim-ues --set gnb.hostname=ueransim-gnb

As we can see gNodeB and pod emulating UE’s are already deployed:

kubectl -n open5gs1 logs deployment/ueransim-gnb

kubectl -n open5gs1 exec -ti deployment/ueransim-gnb-ues -- /bin/bash
bash-5.1# ./entrypoint.sh 
Usage : ./entrypoint.sh [gnb|ue]
bash-5.1# ./entrypoint.sh ue
GNB_IP: 10.244.6.218
Launching ue: nr-ue -c ue.yaml
