Open5GS + multiple load balanced eUPF

Requirements

• helm installed

Attention!

---

this document work in progress!!

now, we dont have solution for routing and NAT with one IP pool and multiple eUPF

check steps not working

Deployment steps

1. install eupf (for example we use 2 replicas of eUPF)

   make upf

check pods and ips:

$ kubectl get po -n open5gs -l "app.kubernetes.io/name=eupf" -o wide
NAME     READY   STATUS    RESTARTS   AGE     IP             NODE      NOMINATED NODE   READINESS GATES
eupf-0   1/1     Running   0          6m29s   10.233.64.17   edgecom   <none>           <none>
eupf-1   1/1     Running   0          6m19s   10.233.64.44   edgecom   <none>           <none>

2. install open5gs

   make open5gs

3. configure SMF

   make smf

4. install gNB

   make gnb

5. install UERANSim

   make ue1

   make ue2

6. check SMF logs:

ue1 is connected and work via eUPF 0 (10.233.64.17)

ue2 is connected and work via eUPF 1 (10.233.64.44)

Check steps

1. exec shell in UE pod

   kubectl -n open5gs exec -ti deployment/ueransim1-ueransim-ues -- /bin/bash

2. run ICMP test

   ping -I uesimtun0 1.1.1.1

Undeploy steps

1. undeploy all

   make clean
