OOM Cloud Setup Guide

OOM deploys and manages ONAP on a pre-established Kubernetes cluster - the creation of this cluster is outside of the scope of the OOM project as there are many options including public clouds with pre-established environments. However, this guide includes instructions for how to create and use some of the more popular environments which could be used to host ONAP. If creation of a Kubernetes cluster is required, the life-cycle of this cluster is independent of the life-cycle of the ONAP components themselves. Much like an OpenStack environment, the Kubernetes environment may be used for an extended period of time, possibly spanning multiple ONAP releases.

Note

Inclusion of a cloud technology or provider in this guide does not imply an endorsement.

Software Requirements

The versions of Kubernetes that are supported by OOM are as follows:

OOM Software Requirements
Release Kubernetes Helm kubectl Docker
amsterdam 1.7.x 2.3.x 1.7.x 1.12.x
beijing 1.8.10 2.8.2 1.8.10 17.03.x
casablanca 1.11.5 2.9.1 1.11.5 17.03.x
dublin 1.13.5 2.12.3 1.13.5 18.09.5

Minimum Hardware Configuration

The hardware requirements are provided below. Note that this is for a full ONAP deployment (all components). Customizing ONAP to deploy only components that are needed will drastically reduce the requirements.

OOM Hardware Requirements
RAM HD vCores Ports
224GB 160GB 112 0.0.0.0/0 (all open)

Note

Kubernetes supports a maximum of 110 pods per node - configurable in the –max-pods=n setting off the “additional kubelet flags” box in the kubernetes template window described in ‘ONAP Development - 110 pod limit Wiki’ - this limit does not need to be modified . The use of many small nodes is preferred over a few larger nodes (for example 14x16GB - 8 vCores each). Subsets of ONAP may still be deployed on a single node.

Cloud Installation

OOM can be deployed on a private set of physical hosts or VMs (or even a combination of the two). The following guide describe the recommended method to setup a Kubernetes cluster: ONAP on HA Kubernetes Cluster.

There are alternative deployment methods described on the Cloud Native Deployment Wiki
