Overview
For ONAP SDN-R load and stress test and Proof of concept, June 19 a three node SDN-R cluster is used. Version is El Alto.
Precondition
- Running performant physical server cluster (The hardware requirements)
- Openstack installed
- VM cloud image ubuntu 18.04-server-image
Goal of this description is to setup a partial ONAP with focus of SDN-R services
Steps
- Installing Kubernetes and Rancher
- Initiation HELM
- Downloading OOM charts
- Installation of SDN-R, LOG, AAI, SO, PORTAL, ROBOT Framework, OOF
- Installartion of Device Simulators
Installing Kubernetes and Rancher (Step 1)
Create the Rancher 3 nodes control cluster named as onap-control on OpenStack
The following instructions describe how to create 3 OpenStack VMs to host the Highly-Available Kubernetes Control Plane. ONAP workloads will not be scheduled on these Control Plane nodes.
Launch new VMs in OpenStack.
Select Ubuntu 18.04 as the boot image for the VM without any volume
Select m1.large flavor
Apply customization script for Control Plane VMs
The script to be copied:
!/bin/bash
DOCKER_VERSION=18.09.5
sudo apt-get update
curl https://releases.rancher.com/install-docker/$DOCKER_VERSION.sh | sh mkdir -p /etc/systemd/system/docker.service.d/ cat > /etc/systemd/system/docker.service.d/docker.conf << EOF [Service] ExecStart= ExecStart=/usr/bin/dockerd -H fd:// --insecure-registry=nexus3.onap.org:10001 EOF
sudo usermod -aG docker ubuntu
systemctl daemon-reload
systemctl restart docker
apt-mark hold docker-ce
IP_ADDR=ip address |grep ens|grep inet|awk '{print $2}'| awk -F / '{print $1}' HOSTNAME=hostname
echo "$IP_ADDR $HOSTNAME" >> /etc/hosts
docker login -u docker -p docker nexus3.onap.org:10001
sudo apt-get install make -y
wget https://storage.googleapis.com/kubernetes-release/release/v1.13.5/bin/linux/amd64/kubectl
chmod +x kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
wget http://storage.googleapis.com/kubernetes-helm/helm-v2.12.3-linux-amd64.tar.gz
tar -zxvf helm-v2.12.3-linux-amd64.tar.gz
sudo mv linux-amd64/helm /usr/local/bin/helm
sudo apt-get update
sudo apt-get upgrade -y
exit 0
This customization script will:
- update ubuntu
- install docker
- install make
- download and install kubectl
- download and install helm
- once again update & upgrade ubuntu
Launched Instances
Create the Kubernetes 12 nodes worker cluster named as onap-k8s on OpenStack cloud
The following instructions describe how to create OpenStack VMs to host the Highly-Available Kubernetes Workers. ONAP workloads will only be scheduled on these nodes.
Launch new VM instances in OpenStack
Select Ubuntu 18.04 as base image
Select Flavor
The size of Kubernetes hosts depend on the size of the ONAP deployment being installed.
If a small subset of ONAP applications are being deployed (i.e. for testing purposes), then 16GB or 32GB may be sufficient.
Networking
Apply customization script for Kubernetes VM(s)

This customization script will:
- update ubuntu
- install docker
- install nfs common
- download and install kubectl
- update and upgrade ubuntu
Launched k8s instances
