-# Overview
-This set of playbooks can be used to deploy an Ambari-managed Hadoop
cluster containing Metron services using Ansible. These playbooks target
RHEL/CentOS 6.x operating
-systems.
-
-Installation consists of -
-- Building Metron tarballs, RPMs and the Ambari MPack
-- Deploying Ambari
-- Leveraging Ambari to install:
- * The required Hadoop Components
- * Core Metron (Parsing, Enrichment, Indexing)
- * Elasticsearch
- * Kibana
-- Starting All Services
-
-## Prerequisites
-The following tools are required to run these scripts:
-
-- [Maven](https://maven.apache.org/)
-- [Git](https://git-scm.com/)
-- [Ansible](http://www.ansible.com/) (2.0.0.2 or 2.2.2.0)
-- [Docker](https://www.docker.com/) (Docker for Mac on OSX)
-
-These scripts depend on two files for configuration:
-
-- hosts - declares which Ansible roles will be run on which hosts
-- group_vars/all - various configuration settings needed to install Metron
-
-For production use, it is recommended that Metron be installed on an
existing cluster managed by Ambari as described in the Installing Management
Pack section below.
-## Ambari
-The Ambari playbook will install a Hadoop cluster including the Metron
Services (Parsing, Enrichment, Indexing). Ambari will also install
Elasticsearch and Kibana.
-
-Currently, the playbooks supports building a local development cluster
running on one node or deploying to a 10 node cluster on AWS EC2.
-
-## Vagrant
-There is a development environment based on Vagrant that is referred to as
"Full Dev". This installs the entire Ambari/Metron stack. This is useful in
testing out changes to the installation procedure.
-
-### Prerequsities
-- Install [Vagrant](https://www.vagrantup.com/) (5.0.16+)
-- Install the Hostmanager plugin for vagrant - Run `vagrant plugin install
vagrant-hostmanager` on the machine where Vagrant is
-installed
-
-### Full-Dev
-Navigate to `metron/metron-deployment/vagrant/full-dev-platform` and run
`vagrant up`.
-
-## Ambari Management Pack
-An Ambari Management Pack can be built in order to make the Metron service
available on top of an existing stack, rather than needing a direct stack
update.
-
-This will set up
-- Metron Parsers
-- Enrichment
-- Indexing
-- GeoIP data
-- Optional Elasticsearch
-- Optional Kibana
-
-### Prerequisites
+This project contains a variety of tools for deploying Apache Metron.
Please refer to the following sections for more information on the best way to
deploy Metron in your environment.
+
+ * [How do I deploy Metron on a single
VM?](#how-do-i-deploy-metron-on-a-single-vm)
+ * [How do I deploy Metron on a large cluster with
Ambari?](#how-do-i-deploy-metron-on-a-large-cluster-with-ambari)
+ * [How do I build RPM packages?](#how-do-i-build-rpm-packages)
+ * [How do I build DEB packages?](#how-do-i-build-deb-packages)
+ * [How do I deploy Metron within AWS?](#how-do-i-deploy-metron-within-aws)
+
+## How do I deploy Metron on a single VM?
+
+#### Who is this for?
+
+If you are new to Metron and just want to explore the functionality that
it offers, this is good place to start. If you are a developer building on
Metron, then this is also a great way to test out your changes.
+
+#### What does this do?
+
+This option will deploy Metron on a virtual machine running on your
computer. This is often referred to as the "Full Dev" environment.
+
+#### How do I do it?
+Follow these [instructions to deploy Metron on a single
VM](vagrant/full-dev-platform/README.md).
+
+#### Where can I get more information?
+* [Full Dev Platform](vagrant/full-dev-platform)
+
+## How do I deploy Metron on a large cluster with Ambari?
+
+#### Who is this for?
+
+If you want to see how Metron can really scale by deploying it on your own
hardware, or even in your own cloud-based environment, this is the best option
for you.
+
+#### What does this do?
+
+This creates a Management Pack (MPack) extension for [Apache
Ambari](https://ambari.apache.org/) that simplifies the provisioning, managing
and monitoring of Metron on large clusters. This allows you to easily install
Metron on a large cluster using a simple, guided process. This also allows you
to monitor cluster health and even secure your cluster with kerberos.
+
+#### How do I do it?
+
+##### Prerequisites
+
- A cluster managed by Ambari 2.4.2+
-- Metron RPMs available on the cluster in the /localrepo directory. See
[RPMs](#rpms) for further information.
-- [Node.js](https://nodejs.org/en/download/package-manager/) repository
installed on the Management UI host
+- Installable Metron packages (either RPMs or DEBs) available on the
cluster, by default, in the `/localrepo` directory.
+- A [Node.js](https://nodejs.org/en/download/package-manager/) repository
installed on the host running the Management and Alarm UI.
+
+##### How do I build the Mpack?
+
+```
+cd metron-deployment
+mvn clean package -Pmpack
+```
-### Building Management Pack
-From `metron-deployment` run
+This results in the Mpack being produced at the following location.
```
-mvn clean package
+metron-deployment/packaging/ambari/metron-mpack/target/metron_mpack-0.4.2.0.tar.gz
