+CLAMP control loop runtime Smoke Tests
+######################################
+
+.. contents::
+    :depth: 3
+
+
+This article explains how to build the CLAMP control loop runtime for development purposes and how to run smoke tests for control loop runtime. To start, the developer should consult the latest ONAP Wiki to familiarize themselves with developer best practices and how-tos to setup their environment, see `https://wiki.onap.org/display/DW/Developer+Best+Practices`.
+
+
+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 copied the settings.xml from oparent to *~/.m2/* directory
+* 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 using Unbuntu 20.04 LTS VM.
+
+Cloning CLAMP control loop runtime and all dependency
+*****************************************************
+
+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 CLAMP control loop runtime and all dependency.
+
+ONAP Policy Framework has dependencies to the ONAP Parent *oparent* module, the ONAP ECOMP SDK *ecompsdkos* module, and the A&AI Schema module.
+
+
+.. code-block:: bash
+   :caption: Typical ONAP Policy Framework Clone Script
+   :linenos:
+
+    #!/usr/bin/env bash
+
+    ## script name for output
+    MOD_SCRIPT_NAME='basename $0'
+
+    ## the ONAP clone directory, defaults to "onap"
+    clone_dir="onap"
+
+    ## the ONAP repos to clone
+    onap_repos="\
+    policy/parent \
+    policy/common \
+    policy/models \
+    policy/clamp \
+    policy/docker "
+
+    ##
+    ## Help screen and exit condition (i.e. too few arguments)
+    ##
+    Help()
+    {
+        echo ""
+        echo "$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;

+    ##
+    while [ $# -gt 0 ]
+    do
+        case $1 in
+            #-d ONAP clone directory
+            -d)
+                shift
+                if [ -z "$1" ]; then
+                    echo "$MOD_SCRIPT_NAME: no clone directory"

+                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 '"'$clone_dir'"'
+
+
+Execution of the script above results in the following directory hierarchy in your *~/git* directory:
+
+    *  ~/git/onap
+    *  ~/git/onap/policy
+    *  ~/git/onap/policy/parent
+    *  ~/git/onap/policy/common
+    *  ~/git/onap/policy/models
+    *  ~/git/onap/policy/clamp
+    *  ~/git/onap/policy/docker
+
+
+Building CLAMP control loop runtime and all dependency
+******************************************************
+
+**Step 1:** Optionally, for a completely clean build, remove the ONAP built modules from your local repository.
+
+    .. code-block:: bash
+
+        rm -fr ~/.m2/repository/org/onap
+
+
+**Step 2:**  A pom such as the one below can be used to build the ONAP Policy Framework modules. Create the *pom.xml* file in the directory *~/git/onap/policy*.
+
+.. code-block:: xml
+   :caption: Typical pom.xml to build the ONAP Policy Framework
+   :linenos:
+
+    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
+        <modelVersion>4.0.0</modelVersion>
+        <groupId>org.onap</groupId>
+        <artifactId>onap-policy</artifactId>
+        <version>1.0.0-SNAPSHOT</version>
+        <packaging>pom</packaging>
+        <name>${project.artifactId}</name>
+        <inceptionYear>2017</inceptionYear>
+        <organization>
+            <name>ONAP</name>
+        </organization>
+
+        <modules>
+            <module>parent</module>
+            <module>common</module>
+            <module>models</module>
+            <module>clamp</module>
+        </modules>
+    </project>
+
+
+**Step 3:** You can now build the Policy framework.
+
+Java artifacts only:
+
+    .. code-block:: bash
+
+       cd ~/git/onap/policy
+       mvn -pl '!org.onap.policy.clamp:policy-clamp-runtime' install
+
+With docker images:
+
+    .. code-block:: bash
+
+       cd ~/git/onap/policy/clamp/packages/
+       mvn clean install -P docker
+
+Running MariaDb and DMaaP Simulator
+***********************************
+
+Running a MariaDb Instance
+++++++++++++++++++++++++++
+
+Assuming you have successfully built the codebase using the instructions above. There are two requirements for the Clamp controlloop runtime component to run, one of them is a
+running MariaDb database instance. The easiest way to do this is to run the docker image locally.
+
+An sql such as the one below can be used to build the SQL initialization. Create the *mariadb.sql* file in the directory *~/git*.
+
+    .. code-block:: SQL
+
+       create database controlloop;
+       CREATE USER 'policy'@'%' IDENTIFIED BY 'P01icY';
+       GRANT ALL PRIVILEGES ON controlloop.* TO 'policy'@'%';
+
+
+Execution of the command above results in the creation and start of the *mariadb-smoke-test* container.
+
+    .. code-block:: bash
+
+       cd ~/git
+       docker run --name mariadb-smoke-test  \
+        -p 3306:3306 \
+        -e MYSQL_ROOT_PASSWORD=my-secret-pw  \
+        --mount type=bind,source=~/git/mariadb.sql,target=/docker-entrypoint-initdb.d/data.sql \
+        mariadb:10.5.8
+
+
+Running the DMaaP Simulator during Development
+++++++++++++++++++++++++++++++++++++++++++++++
+The second requirement for the Clamp controlloop runtime component to run is to run the DMaaP simulator. You can run it from the command line using Maven.
+
+
+Change the local configuration file *src/test/resources/simParameters.json* using the below code:
+
+.. code-block:: json
+
+   {
+     "dmaapProvider": {
+       "name": "DMaaP simulator",
+       "topicSweepSec": 900
+     },
+     "restServers": [
+       {
+         "name": "DMaaP simulator",
+         "providerClass": "org.onap.policy.models.sim.dmaap.rest.DmaapSimRestControllerV1",
+         "host": "localhost",
+         "port": 3904,
+         "https": false
+       }
+     ]
+   }
+
+Run the following commands:
+
+   .. code-block:: bash
+
+      cd ~/git/onap/policy/models/models-sim/policy-models-simulators
+      mvn exec:java  -Dexec.mainClass=org.onap.policy.models.simulators.Main -Dexec.args="src/test/resources/simParameters.json"
+
+
+Developing and Debugging CLAMP control loop runtime
+***************************************************
+
+Running on the Command Line using Maven
++++++++++++++++++++++++++++++++++++++++
+
+Once the mariadb and DMaap simulator are up and running, run the following commands:
+
+   .. code-block:: bash
+
+      cd ~/git/onap/policy/clamp/runtime-controlloop
+      mvn spring-boot:run
+
+
+Running on the Command Line
++++++++++++++++++++++++++++
+
+   .. code-block:: bash
+
+      cd ~/git/onap/policy/clamp/runtime-controlloop
+      java -jar target/policy-clamp-runtime-controlloop-6.1.3-SNAPSHOT.jar
+
+
+Running in Eclipse
+++++++++++++++++++
+
+1. Check out the policy models repository
+2. Go to the *policy-clamp-runtime-controlloop* module in the clamp repo
+3. Specify a run configuration using the class *org.onap.policy.clamp.controlloop.runtime.Application* as the main class
+4. Run the configuration
+

+
+
+Running one or more participant simulators
+++++++++++++++++++++++++++++++++++++++++++
+
+Into *docker\csit\clamp\tests\data* you can find a test case with policy-participant. In order to use that test you can use particpant-simulator.
+Copy the file *src/main/resources/config/application.yaml* and paste into *src/test/resources/*, after that change *participantId* and *participantType* as showed below:
+
+   .. code-block:: yaml
+
+      participantId:
+        name: org.onap.policy.controlloop.PolicyControlLoopParticipant
+        version: 2.3.1
+      participantType:
+        name: org.onap.PM_Policy
+        version: 1.0.0
+
+Run the following commands:
+
+   .. code-block:: bash
+
+      cd ~/git/onap/policy/clamp/participant/participant-impl/participant-impl-simulator
+       java -jar target/policy-clamp-participant-impl-simulator-6.1.3-SNAPSHOT.jar --spring.config.location=src/test/resources/application.yaml
+
+
+Creating self-signed certificate
+++++++++++++++++++++++++++++++++
+
+There is an additional requirement for the Clamp control loop runtime docker image to run, is creating the SSL self-signed certificate.
+
+Run the following commands:
+
+   .. code-block:: bash
+
+      cd ~/git/onap/policy/docker/csit/
+      ./gen_truststore.sh
+      ./gen_keystore.sh
+
+Execution of the commands above results additional files into the following directory *~/git/onap/policy/docker/csit/config*:
+
+    *  ~/git/onap/policy/docker/csit/config/cakey.pem
+    *  ~/git/onap/policy/docker/csit/config/careq.pem
+    *  ~/git/onap/policy/docker/csit/config/caroot.cer
+    *  ~/git/onap/policy/docker/csit/config/ks.cer
+    *  ~/git/onap/policy/docker/csit/config/ks.csr
+    *  ~/git/onap/policy/docker/csit/config/ks.jks
+
+
+Running the CLAMP control loop runtime docker image
++++++++++++++++++++++++++++++++++++++++++++++++++++
+
+Run the following command:
+
+   .. code-block:: bash
+
+      docker run --name runtime-smoke-test \
+       -p 6969:6969 \
+       -e mariadb.host=host.docker.internal \
+       -e topicServer=host.docker.internal \
+       --mount type=bind,source=~/git/onap/policy/docker/csit/config/ks.jks,target=/opt/app/policy/clamp/etc/ssl/policy-keystore  \
+       --mount type=bind,source=~/git/onap/policy/clamp/runtime-controlloop/src/main/resources/application.yaml,target=/opt/app/policy/clamp/etc/ClRuntimeParameters.yaml  \
+       onap/policy-clamp-cl-runtime
