The installation of ONAP Policy is **automated** by design and can be done via Docker as a standalone system.
Various tools, including healthcheck, logs, and Swagger can be used to ensure proper operation.
ONAP Policy Framework: Standalone Quick Start
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This article explains how to build the ONAP Policy Framework and get it running in Docker as a standalone system.
This article assumes that:
* You are using a *\*nix* operating system such as linux or macOS.
* You are using a directory called *git* off your home directory *(~/git)* for your git repositories
* Your local maven repository is in the location *~/.m2/repository*
* You have added settings to access the ONAP Nexus to your M2 configuration, see `Maven Settings Example <https://wiki.onap.org/display/DW/Setting+Up+Your+Development+Environment>`_ (bottom of the linked page)
The procedure documented in this article has been verified to work on a MacBook laptop running macOS Sierra Version 10.12.6 and a HP Z600 desktop running Ubuntu 16.04.3 LTS.
Cloning the ONAP repositories
-----------------------------
Run a script such as the script below to clone the required modules from the `ONAP git repository <https://gerrit.onap.org/r/#/admin/projects/?filter=policy>`_. This script clones the ONAP policy code and also clones some modules that ONAP Policy is dependent on.
ONAP Policy requires all the *policy* modules from the ONAP repository. It also requires the ONAP Parent *oparent* module and the ONAP ECOMP SDK *ecompsdkos* module.
.. code-block:: bash
:caption: Typical ONAP Policy Framework Clone Script
:linenos:
#!/usr/bin/env bash
## script name for output
MOD_SCRIPT_NAME=`basename $0`
## the ONAP clone directory, defaults to "onap"
clone_dir="onap"
## the ONAP repos to clone
onap_repos="\
policy/api \
policy/common \
policy/docker \
policy/drools-applications \
policy/drools-pdp \
policy/engine \
policy/gui \
policy/pap \
policy/pdp"
##
## Help screen and exit condition (i.e. too few arguments)
##
Help()
{
echo ""
echo "$MOD_SCRIPT_NAME - clones all required ONAP git repositories"
echo ""
echo " Usage: $MOD_SCRIPT_NAME [-options]"
echo ""
echo " Options"
echo " -d - the ONAP clone directory, defaults to '.'"
echo " -h - this help screen"
echo ""
exit 255;
}
##
## read command line
##
while [ $# -gt 0 ]
do
case $1 in
#-d ONAP clone directory
-d)
shift
if [ -z "$1" ]; then
echo "$MOD_SCRIPT_NAME: no clone directory"
exit 1
fi
clone_dir=$1
shift
;;
#-h prints help and exists
-h)
Help;exit 0;;
*) echo "$MOD_SCRIPT_NAME: undefined CLI option - $1"; exit 255;;
esac
done
if [ -f "$clone_dir" ]; then
echo "$MOD_SCRIPT_NAME: requested clone directory '$clone_dir' exists as file"
exit 2
fi
if [ -d "$clone_dir" ]; then
echo "$MOD_SCRIPT_NAME: requested clone directory '$clone_dir' exists as directory"
exit 2
fi
mkdir $clone_dir
if [ $? != 0 ]
then
echo cannot clone ONAP repositories, could not create directory '"'$clone_dir'"'
exit 3
fi
for repo in $onap_repos
do
repoDir=`dirname "$repo"`
repoName=`basename "$repo"`
if [ ! -z $dirName ]
then
mkdir "$clone_dir/$repoDir"
if [ $? != 0 ]
then
echo cannot clone ONAP repositories, could not create directory '"'$clone_dir/repoDir'"'
exit 4
fi
fi
git clone https://gerrit.onap.org/r/${repo} $clone_dir/$repo
done
echo ONAP has been cloned into '"'$clone_dir'"'
Execution of the script above results in the following directory hierarchy in your *~/git* directory:
* ~/git/onap
* ~/git/onap/policy
* ~/git/onap/policy/api
* ~/git/onap/policy/common
* ~/git/onap/policy/docker
* ~/git/onap/policy/drools-applications
* ~/git/onap/policy/drools-pdp
* ~/git/onap/policy/engine
* ~/git/onap/policy/gui
* ~/git/onap/policy/pap
* ~/git/onap/policy/pdp
Building ONAP
-------------
**Step 1.** Optionally, for a completely clean build, remove the ONAP built modules from your local repository.
.. code-block:: bash
rm -fr ~/.m2/repository/org/onap
rm -fr ~/.m2/repository/org/openecomp
rm -fr ~/.m2/repisotory/com/att
**Step 2**. A pom such as the one below can be used to build the ONAP Policy Framework modules. Create the *pom.xml* file in the directory *~/git/onap/policy*.
.. code-block:: xml
:caption: Typical pom.xml to build the ONAP Policy Framework
:linenos:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.onap</groupId>
<artifactId>onap-policy</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>${project.artifactId}</name>
<inceptionYear>2017</inceptionYear>
<organization>
<name>ONAP</name>
</organization>
<modules>
<module>common</module>
<module>engine</module>
<module>pdp</module>
<module>pap</module>
<module>drools-pdp</module>
<module>drools-applications</module>
<module>api</module>
<module>gui</module>
<module>docker</module>
</modules>
</project>
**Step 3**. You can now build the ONAP framework
* On *Ubuntu*, just build the Policy Framework tests and all
.. code-block:: bash
cd ~/git/onap
mvn clean install
* On *macOS*, you must build build the ONAP framework with tests turned off first. Then rebuild the framework with tests turned on and all tests will pass. Note: The reason for this behaviour will be explored later.
.. code-block:: bash
cd ~/git/onap
mvn clean install -DskipTests
mvn install
Building the ONAP Policy Framework Docker Images
------------------------------------------------
The instructions here are based on the instructions in the file *~/git/onap/policy/docker/README.md*.
**Step 1.** Build the policy engine docker image:
.. code-block:: bash
cd ~/git/onap/policy/engine/packages/docker/target
docker build -t onap/policy-pe policy-pe
**Step 2.** Build the Drools PDP docker image:
.. code-block:: bash
cd ~/git/onap/policy/drools-pdp/packages/docker/target
docker build -t onap/policy-drools policy-drools
**Step 3.** Build the Policy Nexus docker image:
.. code-block:: bash
cd ~/git/onap/policy/docker
docker build -t onap/policy-nexus policy-nexus
Starting the ONAP Policy Framework Docker Images
------------------------------------------------
In order to run the containers, you can use *docker-compose*. This uses the *docker-compose.yml* yaml file to bring up the ONAP Policy Framework.
SSS
**Step 1.** Make the file config/drools/drools-tweaks.sh executable.
.. code-block:: bash
chmod +x config/drools/drools-tweaks.sh
**Step 2.** Set the IP address to use to be an IP address of a suitable interface on your machine. Save the IP address into the file *config/pe/ip_addr.txt*.
**Step 3.** Set the environment variable *MTU* to be a suitable MTU size for the application.
.. code-block:: bash
export MTU=9126
**Step 4.** Determine if you want policies pre-loaded or not. By default, all the configuration and operational policies will be pre-loaded by the docker compose script. If you do not wish for that to happen, then export this variable:
.. code-block:: bash
export PRELOAD_POLICIES=false
**Step 5.** Run the system using *docker-compose*. Note that on some systems you may have to run the *docker-compose* command as root or using *sudo*. Note that this command takes a number of minutes to execute on a laptop or desktop computer.
.. code-block:: bash
docker-compose up
Installation Complete
---------------------
**You now have a full standalone ONAP Policy framework up and running!**
