This page documents how to get CLAMP up and running on a local machine and also how to get CLAMP loaded and set up in an IDE. We may use the information on this page as input for a page in the CLAMP documentation.

...

1. Check CLAMP out of its repo

   Code Block
   language bash
   git clone "https://gerrit.onap.org/r/clamp"

   
   

2. Change into the "clamp" directory

3. Build CLAMP

   Code Block
   language bash
   mvn clean install

     You may get the following error (See

   Jira Legacy
   server ONAP JIRASystem Jira serverId 425b2b0a4733707d-557c2057-3c0c3a0f-b515ae5e-579789cceedb4fd8aff50176 key CLAMP-944

   )

   Code Block
   language bash
   [ERROR] DOCKER> I/O Error [[docker.io/python:2-slim] "python": Timeout after 120088 ms while waiting on tcp port '[/172.17.0.3:8080]']

   If so, then run the following command to skip integration tests

   Code Block
   language bash
   mvn clean install -DskipITs

   
   

...

1. Open a console and go into the directory extra/bin-for-dev

   Code Block
   language bash
   cd extra/bin-for-dev

   
   

2. Start an instance of the CLAMP MaraDB database in Docker using the helper script. This script uses docker-compose to bring up an instance of the CLAMP MariaDB.

   Code Block
   language bash
   ./start-db.sh

   
   

3. Start an instance of the CLAMP endpoint emulator in Docker using the helper script. This script uses docker-compose to bring up an instance of the CLAMP endpoint emulator.

   Code Block
   language bash
   ./start-emulator.sh

   
   

4. Check that the database and emulator are running

   Code Block
   language bash
   docker ps

   You should see the two images running

Building ControlLoop docker images in CLAMP

Control loop docker images are built in clamp/packages and pushed to ONAP nexus docker registry nexus3.onap.org:10003
using maven command.

Steps are depicted as below:

1. Open a console and go into the directory clamp/packages

   Code Block
   $cd clamp/packages

   
   

2. Run below command

   Code Block
   $mvn clean install -P docker

   Note: This command when run from clamp main directory will build all docker images of Clamp. When run in clamp/packages folder will build
   ControlLoop docker images alone.

3. There is a fabric8, docker-maven-plugin in clamp/packages/policy-clamp-docker/pom.xml which builds 3 docker images and pushes to ONAP nexus docker registry nexus3.onap.org:10003

   Code Block
   onap/policy-clamp-cl-runtime onap/policy-clamp-cl-k8s-ppnt onap/policy-clamp-cl-http-ppnt onap/policy-clamp-cl-pf-ppnt

   
   

4. Configuration to build docker images is present in following files

   Code Block
   $cd clamp/packages/policy-clamp-docker/src/main/docker

   
   

5. Docker images once built can be brought up manually on localhost using docker commands, or through docker-compose in CSIT
   Clone policy docker repo

   Code Block
   $cd docker/csit/ $./run-project-csit.sh clamp

   Note: More detailed information on CSIT is in Testing CLAMP

6. Docker images from docker-compose file in /policy/docker/csit for clamp
