ONAP/ORAN Tutorial

Description

Prerequisites

In order to access the test bed, create a reservationand have it approved by the reservation service. Access to the resources is granted after the reservation is confirmed. Please follow the process shown on the COSMOS getting started page to get started.

Resources required

One of the servers in any of the COSMOS domains.

Tutorial Setup

For this tutorial, the assumption is that the you made a reservation for sb1.cosmos-lab.org domain. Follow the steps below to gain access to the sandbox 1 console and set up nodes with appropriate images.

  1. If you don't have one already, sign up for a ​COSMOS account
  2. Create a resource reservation on sandbox 1
  3. Login into sandbox 1 console (console.sb1.cosmos-lab.org) with two SSH sessions.
  4. Make sure all the resources in the domain are turned off: 
    omf tell -a offh -t system:topo:allres
    For this tutorial we will be using the SB1 servers, srv1-lg1
  5. Load ORAN image oran-20220427.ndz on srv1-lg1: 
    omf load -i oran-20220427.ndz -t srv1-lg1 -r 60

This image is fairly large and will take up to 7 minutes to load.

  1. Turn all the required resources on and check the status 
    omf tell -a on -t srv1-lg1

    omf stat -t system:topo:allres
  2. ssh to the nodes, use option -Y for using GUI. Alos, please make sure to tunnel ports 30091 and 30205 though the console (or use VPN so you can gain subnet access from your local machine).

Tutorial Execution

Check that the services are running by executing the commad: 

root@srv1-lg1:~# kubectl get pods -n onap && kubectl get pods -n nonrtric

The output should look like: 

NAME                                               READY   STATUS                            RESTARTS        AGE

In case you want to build your own ORAN image, start with the ubuntu2004.ndz and remove snapd restriction from it with: 

sudo rm /etc/apt/preferences.d/snapd

Install snapd: 

sudo apt update
sudo apt install snapd

Add to /etc/profile 

export LC_ALL=C.UTF-8
export LANG=C.UTF-8

exit the ssh session and come back. Install a local Kubernetes with ​MicroK8s: 

sudo snap install microk8s --classic

Grab the ​O-RAN installation scripts: 

git clone --recursive https://github.com/sebdet/oran-deployment.git

And then install them 

./oran-deployment/scripts/layer-0/0-setup-microk8s.sh
./oran-deployment/scripts/layer-0/0-setup-charts-museum.sh
./oran-deployment/scripts/layer-0/0-setup-helm3.sh
