VOLTHA Deployment Environment
=============================
All the components in the VOLTHA project are containerized and the default
deployment environment is ``kubernetes``.
Generally VOLTHA is installed in one of two setups:
- A physical ``kubernetes`` cluster, generally used for production deployments.
- A virtual ``kind`` cluster, generally used for development.
Regardless of the chosen environment the deployment process is the same,
more on this later, and the installation can be managed in the same way.
VOLTHA deployment
-----------------
VOLTHA components on top of ``kubernetes`` are managed via ``helm`` charts.
For more information about ``helm`` please refer to the `Official Documentation
<https://helm.sh>`_.
For the sake of this guide all you need to know is that an
``helm`` chart describes all the information required to deploy a component on top of
``kubernetes``, such as: containers, exposed ports and configuration parameters.
A VOLTHA deployment is composed, at its very minimum, by:
* Infrastructure
* A ``kafka`` cluster (can also be a single node)
* An ``etcd`` cluster (can also be a single node)
* ``ONOS`` (single or multi instance)
* [Optional] ``radius`` (for EAPOL based authentication)
* ``VOLTHA``
* ``voltha-core`` and ``ofAgent`` (contained in the same ``helm`` chart)
* Adapters
* [one or more] adapter pair(s) (OLT adapter + ONU Adapter)

VOLTHA Kubernetes deployment
Note that the ``Infrastructure`` components can be deployed outside of the
``kubernetes`` cluster.
