5geve-wp3-dcm-handler script

This repository contains the logic needed for providing a REST API to the Data Collection Manager, in order to handle automatically the life cycle of this component (related to topic subscription/withdrawal and publish operations).

Usage: sudo python3 dcm_rest_client.py [--dcm_ip_address <dcm_ip_address>] [--port <port_number>] [--spanish_site_plugin_ip_port <spanish_site_plugin_ip_port>] [--italian_site_plugin_ip_port <italian_site_plugin_ip_port>] [--french_site_plugin_ip_port <french_site_plugin_ip_port>] [--greek_site_plugin_ip_port <greek_site_plugin_ip_port>] [--log <log_level>]

Default DCM IP address is localhost, default port is 8090, default site brokers IP-ports are default:8090, and default log level is info.

Application API

The REST API provided by the dcm_rest_client.py script can be seen in the corresponding api-docs files in this repository.

Steps to be followed

First of all, install Python 3 in the server which will hold this script.

sudo apt install python3-pip

Then, export some variables related to the language.

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales

After this, install the required packages for this Python script, which can be found in the requirements.txt file.

pip3 install -r requirements.txt

Start the Kafka mirrors you need using the provided script and configuration file example for a sample site (edit the BROKER_IP parameter). Specify the site name as parameter and keep it running. Run one instance for each site you have.

cd kafka_mirror
./create_kafka_mirror.sh spanish

Finally, execute the script.

sudo python3 dcm_rest_client.py --dcm_ip_address localhost --port 8090 --spanish_site_plugin_ip_port localhost:8090 --italian_site_plugin_ip_port localhost:8090 --french_site_plugin_ip_port localhost:8090 --greek_site_plugin_ip_port localhost:8090 --log info
