Distribution User Manual
************************

:depth: 3
Installation
^^^^^^^^^^^^
Requirements
------------
.. container:: paragraph
Distribution is 100% written in Java and runs on any platform
that supports a JVM, e.g. Windows, Unix, Cygwin.
Installation Requirements
#########################
.. container:: ulist
- Downloaded distribution: JAVA runtime environment
(JRE, Java 8 or later, Distribution is tested with the
OpenJDK)
- Building from source: JAVA development kit (JDK,
Java 8 or later, Distribution is tested with the OpenJDK)
- Sufficient rights to install Distribution on the system
- Installation tools
.. container:: ulist
- TAR and GZ to extract from that TAR.GZ
distribution
.. container:: ulist
- Windows for instance
`7Zip <http://www.7-zip.org/>`__
- `Docker <https://www.docker.com/>`__ to run Distribution
inside a Docker container
Build (Install from Source) Requirements
########################################
.. container:: paragraph
Installation from source requires a few development
tools
.. container:: ulist
- GIT to retrieve the source code
- Java SDK, Java version 8 or later
- Apache Maven 3 (the Distribution build environment)
Get the Distribution Source Code
--------------------------------
.. container:: paragraph
The Distribution source code is hosted in ONAP as project distribution.
The current stable version is in the master branch.
Simply clone the master branch from ONAP using HTTPS.
.. container:: listingblock
.. container:: content
.. code:: text
git clone https://gerrit.onap.org/r/policy/distribution
Build Distribution
------------------
.. container:: paragraph
The examples in this document assume that the distribution source
repositories are cloned to:
.. container:: ulist
- Unix, Cygwin: ``/usr/local/src/distribution``
- Windows: ``C:\dev\distribution``
- Cygwin: ``/cygdrive/c/dev/distribution``
.. important::
A Build requires ONAP Nexus
Distribution has a dependency to ONAP parent projects. You might need to adjust your Maven M2 settings. The most current
settings can be found in the ONAP oparent repo: `Settings <https://git.onap.org/oparent/plain/settings.xml>`__.
.. important::
A Build needs Space
Building distribution requires approximately 1-2 GB of hard disc space, 100 MB for the actual build with full
distribution and around 1 GB for the downloaded dependencies.
.. important::
A Build requires Internet (for first build)
During the build, several (a lot) of Maven dependencies will be downloaded and stored in the configured local Maven
repository. The first standard build (and any first specific build) requires Internet access to download those
dependencies.
.. container:: paragraph
Use Maven for a standard build without any tests.

| # mvn clean install -DskipTest | >cd \dev\distribution |
| | >mvn clean install -DskipTests |
+-------------------------------------------------------+--------------------------------------------------------+
.. container:: paragraph
The build takes 2-3 minutes on a standard development laptop. It
should run through without errors, but with a lot of messages from
the build process.
|
.. container:: paragraph
When Maven is finished with the build, the final screen should look
similar to this (omitting some ``success`` lines):

installation. The following example show how to change to the target
directory and how it should look.

Install Distribution
--------------------
.. container:: paragraph
Distribution can be installed in different ways:
.. container:: ulist
- Windows, Unix, Cygwin: manually from a ``.tar.gz`` archive
- Windows, Unix, Cygwin: build from source using Maven, then
install manually
Install Manually from Archive (Windows, 7Zip, GUI)
##################################################
.. container:: paragraph
Download a ``tar.gz`` archive and copy the file into the install
folder (in this example ``C:\distribution``). Assuming you are using 7Zip,
right click on the file and extract the ``tar`` archive.
|
.. container:: content
Extract the TAR archive
.. container:: paragraph
Then right-click on the new created TAR file and extract the actual
distribution.
|
.. container:: content
Extract the distribution
.. container:: paragraph
Inside the new distribution folder you see the main directories: ``bin``,
``etc``and ``lib``
|
.. container:: paragraph
Once extracted, please rename the created folder to
``distribution-full-2.0.2-SNAPSHOT``. This will keep the directory name in
line with the rest of this documentation.
Build from Source
-----------------
Build and Install Manually (Unix, Windows, Cygwin)
##################################################
.. container:: paragraph
Clone the Distribution GIT repositories into a directory. Go to that
directory. Use Maven to build Distribution (all details on building
Distribution from source can be found in *Distribution HowTo: Build*).
.. container:: paragraph
Now, take the ``.tar.gz`` file and install distribution.
Installation Layout
-------------------
.. container:: paragraph
A full installation of distribution comes with the following layout.
.. container:: listingblock
.. container:: content
- bin
- etc
- lib
Running Distribution in Docker
------------------------------
Run in ONAP
###########
.. container:: paragraph
Running distribution from the ONAP docker repository only requires 2
commands:
.. container:: olist arabic
#. Log into the ONAP docker repo
.. container:: listingblock
.. container:: content
::
docker login -u docker -p docker nexus3.onap.org:10003
.. container:: olist arabic
#. Run the distribution docker image
.. container:: listingblock
.. container:: content
::
docker run -it --rm nexus3.onap.org:10003/onap/policy-distribution:latest
Build a Docker Image
####################
.. container:: paragraph
Alternatively, one can use the Dockerfile defined in the Docker
package to build an image.
Distribution Configurations Explained
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Introduction to Distribution Configuration
------------------------------------------
.. container:: paragraph
A distribution engine can be configured to use various combinations
of policy reception handlers, policy decoders and policy forwarders.
The system is built using a plugin architecture. Each configuration
option is realized by a plugin, which can be loaded and
configured when the engine is started. New plugins can be
added to the system at any time, though to benefit from a
new plugin, an engine will need to be restarted.
|
.. container:: paragraph
The distribution already comes with sdc reception handler,
file reception handler, xacml policy decoder, file in csar policy decoder,
xacml policy forwarder, apex policy forwarder.
General Configuration Format
----------------------------
.. container:: paragraph
The distribution configuration file is a JSON file containing a few
main blocks for different parts of the configuration. Each
block then holds the configuration details. The following
code shows the main blocks:
.. container:: listingblock
.. container:: content
.. code:: text
{
"restServerParameters":{
... (1)
},
"receptionHandlerParameters":{ (2)
"pluginHandlerParameters":{ (3)
"policyDecoders":{...}, (4)
"policyForwarders":{...} (5)
}
},
"receptionHandlerConfigurationParameters":{
... (6)
}
,
"policyForwarderConfigurationParameters":{
... (7)
}
,
"policyDecoderConfigurationParameters":{
... (8)
}
}
.. container:: colist arabic
+-----------------------------------+-----------------------------------+
| **1** | rest server configuration |
+-----------------------------------+-----------------------------------+
| **2** | reception handler plugin |
| | configurations |
+-----------------------------------+-----------------------------------+
| **3** | plugin handler parameters |
| | configuration |
+-----------------------------------+-----------------------------------+
| **4** | policy decoder plugin |

A configuration example
-----------------------
.. container:: paragraph
The following example loads HPA use case related plug-ins.

Notifications are consumed from SDC through SDC client.
Consumed artifacts format is CSAR.
