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

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.

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

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.

Delete the failed module

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

...

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

Reinstall module

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

...

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':

Create the Kubernetes 12 nodes worker cluster named as onap-workers on OpenStack cloud

Launch new VM instances in OpenStack

Select Ubuntu 20.04 as base image

Select Flavor

Networking

Apply customization script for Kubernetes VM(s)

Launched onap-workers instances

Configure Rancher Kubernetes Engine

Install RKE

Prepare cluster.yml

Run RKE

Validate RKE deployment

Verify the kubernetes cluster

Install Helm

Resulting example

Configure NFS Share on Master node

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

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

ONAP Installation

Clone the OOM helm repository

Perform these on the home directory

Make charts from oom repository

Deploying ONAP

Deploying ONAP with helm command

Verify the deploy:

In case of missing or failures in deployment.

Missing deployment

Check the failed modules

Delete the failed module

Reinstall module

Undeploy ONAP
