Goal of this description is to setup a complete ONAP with focus of SDNC services

Steps

Installing Docker, Kubernetes and Rancher
Initiation of HELM
Downloading OOM charts
Installation of all OOM based ONAP componnents
Installation of Device Simulators

OpenStack Preparation

Required Security Groups Rules

Installing Kubernetes and Rancher

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 20.04 as the boot image for the virtual machine without any volume

Select m4.large flavor

Networking

Apply customization script for Control Plane VMs

The script to be copied:

#!/bin/bash

DOCKER_VERSION=19.03.15

sudo apt-get update

curl https://releases.rancher.com/install-docker/$DOCKER_VERSION.sh | sh

docker login -u docker -p docker nexus3.onap.org:10001

sudo apt-get install make -y

#nfs server
sudo apt-get install nfs-kernel-server -y
sudo mkdir -p /dockerdata-nfs
sudo chown nobody:nogroup /dockerdata-nfs/


exit 0

This customization script will:

Update Ubuntu
Install docker and hold the docker version to 19.03.15
set hosts file with IP and hostname
install nfs-kernel-server

Launched Instances

Create the Kubernetes 12 nodes worker cluster named as onap-workers 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 20.04 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)

Launched onap-workers instances

Configure Rancher Kubernetes Engine

Install RKE

Download and install RKE on the onap-control-01 VM. Binaries can be found here for Linux and Mac: https://github.com/rancher/rke/releases/download/v1.2.7/

Perform this on the onap-control-01 VM which has key to access the created VMs.

In our setup, the key of OpenStack controller has also been placed in onap-control-01 and used to login into VMs, so these steps have been performed on onap-control-01 VM.

mkdir rke
cd rke/
wget https://github.com/rancher/rke/releases/download/v1.2.7/rke_linux-amd64
mv rke_linux-amd64 rke
chmod 754 rke

RKE requires a cluster.yml as input. An example file is show below that describes a Kubernetes cluster that will be mapped onto the OpenStack VMs created earlier in this guide.

Example: cluster.yml

The example file:

Prepare cluster.yml

Before this configuration file can be used the IP address must be mapped for each control and worker node in this file.

Run RKE

From within the same directory as the cluster.yml file, simply execute:

ubuntu@onap-control-01:~/rke$ ./rke up

./rke up

The output will look something like:

Install helm chartmuseum plugin

Add chartmuseum plugin to helm

ubuntu@onap-control-01:~$ helm plugin install https://github.com/chartmuseum/helm-push.git

Setting up the NFS share for multinode kubernetes cluster:

Deploying applications to a Kubernetes cluster requires Kubernetes nodes to share a common, distributed filesystem. In this tutorial, we will setup an NFS Master, and configure all Worker nodes a Kubernetes cluster to play the role of NFS slaves.

It is recommneded that a separate VM, outside of the kubernetes cluster, be used. This is to ensure that the NFS Master does not compete for resources with Kubernetes Control Plane or Worker Nodes.

Launch new NFS Server VM instance

Select Ubuntu 18.04 as base image

Select Flavor

This customization script will:

Install docker and hold the docker version to 18.09.5
insert hostname and IP address of the onap-nfs-server in the hosts file
install nfs server

Resulting example

Configure NFS Share on Master node

Login into onap-nfs-server and perform the below commands

Create a master_nfs_node.sh file as below:

master_nfs_node.sh

#!/bin/bash

usage () {
  echo "Usage:"
  echo "   ./$(basename $0) node1_ip node2_ip ... nodeN_ip"
  exit 1
}

if [ "$#" -lt 1 ]; then
  echo "Missing NFS slave nodes"
  usage
fi

#Install NFS kernel
sudo apt-get update
sudo apt-get install -y nfs-kernel-server

#Create /dockerdata-nfs and set permissions
sudo mkdir -p /dockerdata-nfs
sudo chmod 777 -R /dockerdata-nfs
sudo chown nobody:nogroup /dockerdata-nfs/

#Update the /etc/exports
NFS_EXP=""
for i in $@; do
  NFS_EXP+="$i(rw,sync,no_root_squash,no_subtree_check) "
done
echo "/dockerdata-nfs "$NFS_EXP | sudo tee -a /etc/exports

#Restart the NFS service
sudo exportfs -a
sudo systemctl restart nfs-kernel-server

Make the above created file as executable and run the script in the onap-nfs-server with the IP's of the worker nodes:

chmod +x master_nfs_node.sh
sudo ./master_nfs_node.sh {list kubernetes worker nodes ip}
example from the WinLab setup:
sudo ./master_nfs_node.sh 10.31.4.21 10.31.4.22 10.31.4.23 10.31.4.24 10.31.4.25 10.31.4.26 10.31.4.27 10.31.4.28 10.31.4.29 10.31.4.30

Login into each kubernetes worker node, i.e. onap-k8s VMs and perform the below commands

Create a slave_nfs_node.sh file as below:

slave_nfs_node.sh

#!/bin/bash

usage () {
  echo "Usage:"
  echo "   ./$(basename $0) nfs_master_ip"
  exit 1
}

if [ "$#" -ne 1 ]; then
  echo "Missing NFS mater node"
  usage
fi

MASTER_IP=$1

#Install NFS common
sudo apt-get update
sudo apt-get install -y nfs-common

#Create NFS directory
sudo mkdir -p /dockerdata-nfs

#Mount the remote NFS directory to the local one
sudo mount $MASTER_IP:/dockerdata-nfs /dockerdata-nfs/
echo "$MASTER_IP:/dockerdata-nfs /dockerdata-nfs  nfs auto,nofail,noatime,nolock,intr,tcp,actimeo=1800 0 0" | sudo tee -a /etc/fstab

Make the above created file as executable and run the script in all the worker nodes:

chmod +x slave_nfs_node.sh
sudo ./slave_nfs_node.sh {master nfs node IP address}
example from the WinLab setup:
sudo ./slave_nfs_node.sh 10.31.3.11

ONAP Installation

Perform the following steps in onap-control-01 VM.

Clone the OOM helm repository

Perform these on the home directory

Clone oom repository with recursive submodules option
Add deploy plugin to helm
Add undeploy plugin to helm
Add helm local repository to the local running server

ubuntu@onap-control-01:~$ git clone -b master http://gerrit.onap.org/r/oom --recurse-submodules

ubuntu@onap-control-01:~$ helm plugin install ~/oom/kubernetes/helm/plugins/deploy

ubuntu@onap-control-01:~$ helm plugin install ~/oom/kubernetes/helm/plugins/undeploy

ubuntu@onap-control-01:~$ helm repo add local http://127.0.0.1:8080

Make charts from oom repository

Do not use sudo to perform the 'make' operation

This will take somewhere around 20-30 minutes of time to make all the helm charts and save the charts into local helm repository.

ubuntu@onap-control-01:~$ cd ~/oom/kubernetes; make all -e SKIP_LINT=TRUE; make onap -e SKIP_LINT=TRUE
Using Helm binary helm which is helm version v3.5.2

In case of missing or failures in deployment.

If the deployment of any onap module fails, please go through these steps to redeploy the modules.

In this example, we demonstrate failure of dmaap, which normally occurs due to timeout issues.

Missing deployment

In the above deployment, demo-sdnc is missing. So we reinstall this.

ubuntu@onap-control-01:~/oom/kubernetes$ helm install --namespace onap demo-sdnc local/sdnc --set global.masterPassword=WinLab_NetworkSlicing -f onap/resources/overrides/environment.yaml -f onap/resources/overrides/onap-all.yaml --timeout 1200s
NAME: demo-sdnc
LAST DEPLOYED: Tue Jul 13 16:11:58 2021
NAMESPACE: onap
STATUS: deployed
REVISION: 1
TEST SUITE: None
ubuntu@onap-control-01:~/oom/kubernetes$

Check the failed modules

perform 'helm ls' on the control node.

Delete the failed module

use the right release name from the name as shown in helm ls.

The below commands will delete all the pods and dependencies.

helm delete demo-dmaap
kubectl get persistentvolumeclaims -n onap | grep demo-dmaap | sed -r 's/(^[^ ]+).*/kubectl delete persistentvolumeclaims -n onap \1/' | bash
kubectl get persistentvolumes      -n onap | grep demo-dmaap | sed -r 's/(^[^ ]+).*/kubectl delete persistentvolumes      -n onap \1/' | bash
kubectl get secrets                -n onap | grep demo-dmaap | sed -r 's/(^[^ ]+).*/kubectl delete secrets                -n onap \1/' | bash
kubectl get clusterrolebindings    -n onap | grep demo-dmaap | sed -r 's/(^[^ ]+).*/kubectl delete clusterrolebindings    -n onap \1/' | bash
kubectl get jobs                   -n onap | grep demo-dmaap | sed -r 's/(^[^ ]+).*/kubectl delete jobs                   -n onap \1/' | bash
kubectl get pods                   -n onap | grep demo-dmaap | sed -r 's/(^[^ ]+).*/kubectl delete pods                   -n onap \1/' | bash

Delete any residue data from onap-nfs-server.

cd /dockerdata-nfs/
sudo rm -r demo-dmaap/

Reinstall module

Reinstall the deleted module with the same release name as used in the deletion

helm install --namespace onap -n demo-dmaap local/dmaap --set global.masterPassword=WinLab_NetworkSlicing -f onap/resources/overrides/environment.yaml -f onap/resources/overrides/onap-all.yaml --timeout 1200s

You can verify the deployment in a parallel terminal by checking the pods using the command

kubectl get pods -n onap | grep demo-dmaap

This shall show you the status of the upcoming pods during the deployment wait time.

Once this is deployed, you can verify using the "helm ls" command to check all the required modules are up and running.

Undeploy ONAP

For the release name 'demo' and namespace 'onap':

Perform these below commands in onap-control-1 where the helm was deployed.

helm undeploy demo
kubectl get persistentvolumeclaims -n onap | grep demo | sed -r 's/(^[^ ]+).*/kubectl delete persistentvolumeclaims -n onap \1/' | bash
kubectl get persistentvolumes      -n onap | grep demo | sed -r 's/(^[^ ]+).*/kubectl delete persistentvolumes      -n onap \1/' | bash
kubectl get secrets                -n onap | grep demo | sed -r 's/(^[^ ]+).*/kubectl delete secrets                -n onap \1/' | bash
kubectl get clusterrolebindings    -n onap | grep demo | sed -r 's/(^[^ ]+).*/kubectl delete clusterrolebindings    -n onap \1/' | bash
kubectl get jobs                   -n onap | grep demo | sed -r 's/(^[^ ]+).*/kubectl delete jobs                   -n onap \1/' | bash
kubectl get pods                   -n onap | grep demo | sed -r 's/(^[^ ]+).*/kubectl delete pods                   -n onap \1/' | bash

Perform the below commands in onap-nfs-server.

This is to delete all the network shared data which will not be deleted on purge delete of helm release.

cd /dockerdata-nfs/
sudo rm -r *

e.g.
ubuntu@onap-nfs-server:~$ cd /dockerdata-nfs/
ubuntu@onap-nfs-server:/dockerdata-nfs$ sudo rm -r *

ES-DB index read only – NFS out of disc space

ONAP log (elastic DB) consumes approx 1 GB per day. If disc space crosses a threshold, indindices of SDNC elastic DB are set to read-only.

** FORBIDDEN/12/index read-only / allow delete (api)] **

Housekeeping of elastic db can be done by Curator.
