Covid-19 data from RKI Visualisation with grafana influxdb & Node-Red

Basic Concept

As a big fan of containerised applications, I decided to fetch the latest covid api data from RKI (Robert Koch Institute) website. Fetch api data from Python and automate the script in the Node-RED to fetch the latest data every day at 3:00 am. Save it to influxdb and visualise it in the Grafana dashboard.

Installation Requirements

• Docker and Docker Compose should be installed on the system.

Steps to run the docker containers

• From the root of this repo you will find the file name docker-compose.yml. Edit this file according to your requirements and run on the host.

Example:
docker-compose pull
docker-compose up -d

• Check if the all the containers are running by executing docker ps.

• Open the UI of Node-RED to import the flow from the file nodered_flow.json in order to run the Python script in it.

• See Example below:

• Import the grafana dashboard model from the file grafana_dashboard_model.json in the grafana UI.

• Visualisation example of Covid Dashboard see below:
