CLAMP Automation Composition Smoke Tests

This article explains how to build the CLAMP automation composition for development purposes and how to run smoke tests for automation composition. 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 (bottom of the linked page)

The procedure documented in this article has been verified using Ubuntu 20.04 LTS VM.

Cloning CLAMP automation composition and all dependency

Run a script such as the script below to clone the required modules from the ONAP git repository. This script clones CLAMP automation composition 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.

Typical ONAP Policy Framework Clone Script
 1 #!/usr/bin/env bash
 2
 3 ## script name for output
 4 MOD_SCRIPT_NAME='basename $0'
 5
 6 ## the ONAP clone directory, defaults to "onap"
 7 clone_dir="onap"
 8
 9 ## the ONAP repos to clone
10 onap_repos="\
11 policy/parent \
12 policy/common \
13 policy/models \
14 policy/clamp \
15 policy/docker "
16
17 ##
18 ## Help screen and exit condition (i.e. too few arguments)
19 ##
20 Help()
21 {
22     echo ""
23     echo "$MOD_SCRIPT_NAME - clones all required ONAP git repositories"
24     echo ""
25     echo "       Usage:  $MOD_SCRIPT_NAME [-options]"
26     echo ""
27     echo "       Options"
28     echo "         -d          - the ONAP clone directory, defaults to '.'"
29     echo "         -h          - this help screen"
30     echo ""
31     exit 255;

41         -d)
42             shift
43             if [ -z "$1" ]; then
44                 echo "$MOD_SCRIPT_NAME: no clone directory"
45                 exit 1
46             fi
47             clone_dir=$1
48             shift
49         ;;

52         -h)
53             Help;exit 0;;
54
55         *)    echo "$MOD_SCRIPT_NAME: undefined CLI option - $1"; exit 255;;
56     esac
57 done
58
59 if [ -f "$clone_dir" ]; then
60     echo "$MOD_SCRIPT_NAME: requested clone directory '$clone_dir' exists as file"
61     exit 2
62 fi
63 if [ -d "$clone_dir" ]; then
64     echo "$MOD_SCRIPT_NAME: requested clone directory '$clone_dir' exists as directory"
65     exit 2
66 fi
67
68 mkdir $clone_dir
69 if [ $? != 0 ]
70 then
71     echo cannot clone ONAP repositories, could not create directory '"'$clone_dir'"'
72     exit 3
73 fi
74
75 for repo in $onap_repos
76 do
77     repoDir=`dirname "$repo"`
78     repoName=`basename "$repo"`
79
80     if [ ! -z $dirName ]
81     then
82         mkdir "$clone_dir/$repoDir"
83         if [ $? != 0 ]
84         then
85             echo cannot clone ONAP repositories, could not create directory '"'$clone_dir/repoDir'"'
86             exit 4
87         fi
88     fi
89
90     git clone https://gerrit.onap.org/r/${repo} $clone_dir/$repo
91 done
92
93 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 automation composition and all dependency

Step 1: Optionally, for a completely clean build, remove the ONAP built modules from your local repository.

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.

Typical pom.xml to build the ONAP Policy Framework
 1  <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">
 2      <modelVersion>4.0.0</modelVersion>
 3      <groupId>org.onap</groupId>
 4      <artifactId>onap-policy</artifactId>
 5      <version>1.0.0-SNAPSHOT</version>
 6      <packaging>pom</packaging>
 7      <name>${project.artifactId}</name>
 8      <inceptionYear>2017</inceptionYear>
 9      <organization>
10          <name>ONAP</name>
11      </organization>
12
13      <modules>
14          <module>parent</module>
15          <module>common</module>
16          <module>models</module>
17          <module>clamp</module>
18      </modules>
19  </project>

Step 3: You can now build the Policy framework.

Build java artifacts only:

cd ~/git/onap/policy
mvn -pl '!org.onap.policy.clamp:policy-clamp-runtime' install

Build with docker images:

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 automation composition 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.

A sql such as the one below can be used to build the SQL initialization. Create the mariadb.sql file in the directory ~/git.

create database clampacm;
CREATE USER 'policy'@'%' IDENTIFIED BY 'P01icY';
GRANT ALL PRIVILEGES ON clampacm.* TO 'policy'@'%';

Execution of the command above results in the creation and start of the mariadb-smoke-test container.

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 automation composition 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:

{
  "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:

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 automation composition

Running on the Command Line using Maven

Once the mariadb and DMaap simulator are up and running, run the following commands:

cd ~/git/onap/policy/clamp/runtime-acm
mvn spring-boot:run

Running on the Command Line

cd ~/git/onap/policy/clamp/runtime-acm
java -jar target/policy-clamp-runtime-acm-6.2.2-SNAPSHOT.jar

Running in Eclipse

  1. Check out the policy models repository

  2. Go to the policy-clamp-runtime-acm module in the clamp repo

  3. Specify a run configuration using the class org.onap.policy.clamp.acm.runtime.Application as the main class

  4. Run the configuration

Swagger UI of Automation composition is available at http://localhost:6969/onap/policy/clamp/acm/swagger-ui/, and swagger JSON at http://localhost:6969/onap/policy/clamp/acm/v2/api-docs/

Running one or more participant simulators

Into dockercsitclamptestsdata 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:

participantId:
  name: org.onap.PM_Policy
  version: 1.0.0
participantType:
  name: org.onap.policy.clamp.acm.PolicyParticipant
  version: 2.3.1

Run the following commands:

cd ~/git/onap/policy/clamp/participant/participant-impl/participant-impl-simulator
java -jar target/policy-clamp-participant-impl-simulator-6.2.2-SNAPSHOT.jar --spring.config.location=src/main/resources/config/application.yaml

Creating self-signed certificate

There is an additional requirement for the Clamp automation composition docker image to run, is creating the SSL self-signed certificate.

Run the following commands:

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 automation composition docker image

Run the following command:

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-acm/src/main/resources/application.yaml,target=/opt/app/policy/clamp/etc/AcRuntimeParameters.yaml  \
 onap/policy-clamp-runtime-acm

Using CLAMP runtime to connect to CLAMP automation composition

Build CLAMP runtime image:

cd ~/git/onap/policy/clamp/runtime
mvn clean install -P docker -DskipTests

Run the following docker composition:

version: '3.1'

services:
  db:
    image: mariadb:10.5.8
    volumes:
       - "~/git/onap/policy/clamp/runtime/extra/sql/:/docker-entrypoint-initdb.d:rw"
