Installing PNDA During Helm Chart Based DCAE Deployment
=======================================================
PNDA is integrated into ONAP as a component system of DCAE. It is possible to deploy PNDA as
part of an ONAP OOM deployment on Openstack infrastructure. This is achieved by using a
pnda-bootstrap container in kubernetes to deploy Openstack VMs and then install a PNDA cluster
onto those VMs.
Requirements
------------
PNDA deployment within ONAP requires the following:
* Openstack based infrastructure. Follow the `PNDA guide <http://pnda.io/pnda-guide/provisioning/openstack/PREPARE.html>`_
for more information.
* OOM / Helm template based installation of ONAP on Kubernetes.
* Kubernetes and PNDA need to share the same Openstack network subnet.
The dcae-pnda-bootstrap Helm chart currently deploys a PNDA cluster with the following resource
requirements:
+--------------------+--------------------+--------------------+--------------------+
|Node | CPU | RAM GB | Disk GB |
+====================+====================+====================+====================+
|Gateway | 2 | 4 | 20 |
+--------------------+--------------------+--------------------+--------------------+
|Edge | 8 | 32 | 50 |
+--------------------+--------------------+--------------------+--------------------+
|Hadoop Manager | 4 | 16 | 50 |
+--------------------+--------------------+--------------------+--------------------+
|Hadoop Data x 2 | 4 | 8 | 20 + 45 |
+--------------------+--------------------+--------------------+--------------------+
|Kafka | 2 | 8 | 50 |
+--------------------+--------------------+--------------------+--------------------+
There are several parameters that need to be defined with values from your environment for a
successful PNDA deployment within ONAP. These parameters can be grouped in separate files that
are passed as parameters to helm install. With the following files, the command to install ONAP
with PNDA would then look like this:
::
helm install -f ~/pnda.yaml -f ~/pnda-openstack.yaml -f ~/pnda-pem.yaml local/onap -n dev --namespace onap
``pnda.yaml``

This file contains settings to enable PNDA install and the evironment settings required by PNDA.
