Running Blueprints Processor Microservice in an IDE
====================================================

Objective
~~~~~~~~~~~~

Have the processor running locally is to use the IDE to run the code, while having the database running in a container. 
This way, code changes can be conveniently tested and debugged.


Check out the code
~~~~~~~~~~~~~~~~~~~

Check out the code from Gerrit: https://gerrit.onap.org/r/#/admin/projects/ccsdk/cds

Build it locally
~~~~~~~~~~~~~~~~~~

In the checked out directory, type

.. code-block:: bash

   mvn clean install -DskipTests=true -Dmaven.test.skip=true -Dmaven.javadoc.skip=true -Dadditionalparam=-Xdoclint:none

Spin up a Docker container with the database
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Blueprints Processor project uses a database to store information about the blueprints 
and therefore it needs to be online before attempting to run it.

One way to create the database is by using the :file:`docker-compose.yaml` 
file present on the distribution module. This database will require a local directory to mount a volume, before running docker-compose remember to create following directory:

.. code-block:: bash

   mkdir -p -m 755 /opt/app/cds/mysql/data

Navigate to the docker-compose file in the distribution module:

.. tabs::

   .. group-tab:: Latest

      .. code-block:: bash

         cd ms/blueprintsprocessor/application/src/main/dc

   .. group-tab:: Frankfurt

      .. code-block:: bash

         cd ms/blueprintsprocessor/application/src/main/dc

   .. group-tab:: El Alto

      .. code-block:: bash

         ms/blueprintsprocessor/distribution/src/main/dc

   .. group-tab:: Dublin

      .. code-block:: bash

         ms/blueprintsprocessor/distribution/src/main/dc

And run docker-composer:

.. code-block:: bash

    docker-compose up -d db

This should spin up a container of the MariaDB image in the background.
To check if it has worked, this command can be used:

.. code-block:: bash

    docker-compose logs -f

The phrase ``mysqld: ready for connections`` indicates that the database was started correctly.

From now on, the Docker container will be available on the computer; if it ever gets stopped,
it can be started again by the command:

.. code-block:: bash

   docker start <id of mariadb container>


Set permissions on the local file system
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Blueprints processor uses the local file system for some operations and, therefore,
need some existing and accessible paths to run properly.

Execute the following commands to create the needed directories, and grant access to the current user to modify them:

.. code-block:: bash

   mkdir -p -m 755 /opt/app/onap/blueprints/archive
   mkdir -p -m 755 /opt/app/onap/blueprints/deploy
   mkdir -p -m 755 /opt/app/onap/scripts
   sudo chown -R $(id -u):$(id -g) /opt/app/onap/

Import the project on the IDE
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For this page, the chosen IDE is IntelliJ, but the instructions present here can
be adapted to be used in other IDEs as well.

Go to *File | Open* and choose the :file:`pom.xml` file of the cds directory:

|imageImportProject|

Sometimes it may be necessary to reimport Maven project:

|imageReimportMaven|


Override some application properties
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After the project is compiled, a Run Configuration profile overriding some application properties
with custom values needs to be created, to reflect the local environment characteristics.

   .. group-tab:: Latest

      Navigate to the main class of the Blueprints Processor, the BlueprintProcessorApplication class:

      ``ms/blueprintsprocessor/application/src/main/kotlin/org/onap/ccsdk/cds/blueprintsprocessor/BlueprintProcessorApplication.kt``.

      Right-click inside it, at any point, to load the context menu and select create 
      BlueprintProcessorApplication configuration from context:

      |imageCreateRunConfigkt|

      **The following window will open:**

      |imageRunConfigKt|

      **Add the following in the field `VM Options`:**

      .. code-block:: bash
         :caption: **Custom values for properties**

         -Dspring.profiles.active=dev

      You can override any value from **application-dev.properties** file here. Use the following pattern:

      .. code-block:: java

         -D<application-dev.properties key>=<application-dev.properties value>

Add/replace the following in Blueprint's application-dev.properties file:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: java

   blueprintsprocessor.grpcclient.remote-python.type=token-auth
   blueprintsprocessor.grpcclient.remote-python.host=localhost
   blueprintsprocessor.grpcclient.remote-python.port=50051
   blueprintsprocessor.grpcclient.remote-python.token=Basic Y2NzZGthcHBzOmNjc2RrYXBwcw==

   blueprintprocessor.remoteScriptCommand.enabled=true


Run the application
~~~~~~~~~~~~~~~~~~~

Select either run or debug for this Run Configuration to start the Blueprints Processor:

|imageRunDebug|

|imageBuildLogs|


Testing the application
~~~~~~~~~~~~~~~~~~~~~~~~~

There are two main features of the Blueprints Processor that can be of interest of a developer:
blueprint upload and blueprint process.

To upload custom blueprints,  the endpoint ``api/v1/execution-service/upload`` is used.

To process, the endpoint is ``api/v1/execution-service/process``.

Postman is a software that can be used to send these request, and an example of
them is present on https://www.getpostman.com/collections/b99863b0cde7565a32fc.


Possible Fixes
~~~~~~~~~~~~~~~~~~~

Imported packages or annotiations are not found, Run Config not available?
*****************************************************************************

1. Rebuild with ``maven install ...`` (see above)
2. Potentially change Maven home directory in Settings
3. Maven reimport in IDE

Compilation error?
********************

* Change Java Version to 11 or 8
