Prerequisites

• docker
• helm
• k8s

Docker Installation

curl -fsSL https://get.docker.com -o get-docker.sh

sudo sh get-docker.sh

Docker without sudo:

sudo usermod -aG docker $USER     

newgrp docker 

Helm Installation

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3

chmod 700 get_helm.sh

./get_helm.sh

K8S cluster Installation

1. Add Kubernetes Signing Key

curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add

2. Add Software Repositories

sudo apt-add-repository "deb http://apt.kubernetes.io/ kubernetes-xenial main"

PS.: if it fails on finding apt-add-repository command, install the package below:

sudo apt-get install software-properties-common -y

3. Kubernetes Installation Tools

sudo apt-get install kubeadm kubelet kubectl
sudo apt-mark hold kubeadm kubelet kubectl

4. disabling the swap memory on each server:

sudo swapoff -a

5. Assign Unique Hostname for Each Server Node

sudo hostnamectl set-hostname master-node

6. Initialize Kubernetes on Master Node

sudo kubeadm init --pod-network-cidr=10.244.0.0/16

PS.: in case of error

[ERROR CRI]: container runtime is not running: output: time="2020-09-24T11:49:16Z" level=fatal msg="getting status of runtime failed: rpc error: code = Unimplemented desc = unknown service runtime.v1alpha2.RuntimeService"
, error: exit status 1

follow the steps below and retry the init:

rm /etc/containerd/config.toml
systemctl restart containerd

7. to create a directory for the cluster:

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

8. Deploy Pod Network to Cluster

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

OBS: if the pod got tainted do:

kubectl taint nodes --all node-role.kubernetes.io/master-

in case of any other taint errors, use 'kubectl describe node' to find out more about it (check the field: Taints)

Install SDRAN

# Add project helm repositories
helm repo add cord https://charts.opencord.org
helm repo add atomix https://charts.atomix.io
helm repo add onos https://charts.onosproject.org
helm repo add sdran https://sdrancharts.onosproject.org

# Update repository helm
helm repo update

# Install atomix
helm install atomix-controller atomix/atomix-controller -n kube-system --version 0.6.9

helm install atomix-raft-storage atomix/atomix-raft-storage -n kube-system --version 0.1.25

# Install Onos-operator
helm install -n kube-system onos-operator onos/onos-operator --version 0.5.2

# Install ran-simulator e do onos-kpimon flags
helm -n sdran install sd-ran sdran/sd-ran --set import.ran-simulator.enabled=true --set import.onos-kpimon.enabled=true --set ran-simulator.pci.modelName=your-modal-name --version 1.4.2

helm install -n sdran onos-exporter sdran/onos-exporter --set import.fluent-bit.enabled=true --set import.opensearch.enabled=true --set import.prometheus-stack.enabled=true

OBS: Precisa realizar o seguinte ajuste devido o opensearch e em seguida restartar o docker:

sysctl -w vm.max_map_count=262144
systemctl restart docker.service

RANSim usando um modelo diferente

obs: nao está funcionando dessa forma e está passando atraves da flag --set ran-simulator.pci.modelName=two-cell-two-node-model.

Por default, o RANSim usa o model.yaml como arquivo modelo. Para usar um diferente específico deve-se:

Dentro do pod onos-cli executar:

wget https://raw.githubusercontent.com/onosproject/sdran-helm-charts/master/ran-simulator/files/model/model-5cell-100ue.yaml


onos ransim load --data=/home/onos/model-5cell-100ue.yaml --data-name=model-5cell-100ue.yaml
