Submitted as part of an application to the position of developer trainee at Reaktor.

Hosted version will be up at https://reaktorbirdnest.jaspnas.com for a limited time.

Running the project

get certificates from CA (e.g. letsencrypt) or run the following command openssl genrsa -des3 -passout pass:x -out server.pass.key 2048 && openssl rsa -passin pass:x -in server.pass.key -out key.pem && rm server.pass.key && openssl req -new -key key.pem -out server.csr -subj "/C=FI/ST=Turku/L=Turku/O=JaspnasCom/OU=IT Department/CN=reaktorbirdnest.jaspnas.com" && openssl x509 -req -days 100 -in server.csr -signkey key.pem -out cert.crt to generate a self-signed certificate.

Put the cert and key into /root/reaktorbirdnest.jaspnas.com.crt and /root/reaktorbirdnest.jaspnas.com-key.pem

docker compose up -d in the root directory

Description

The project consist of 4 docker containers running on a separate network using Docker compose.

Backend

The backend module updates the database and serves information about drones to clients. It is written in golang.

Frontend

The frontend module is written in react and shows the data fetched from the backend.

Mongo

The project uses mongodb to store drones.

Yxorp

The project uses nginx as a reverse proxy to distribute traffic between the frontend and backend.

Tying it togehter

The frontend first requests data from the backend using a get request to the /api/drones endpoint. After this it connects to a websocket at /api/websocket that continuosly sends all drones caught violating the protected area. The valid (CA-signed) certificates are only stored on the reverse proxy server while backend and frontend use randomly generated certificates.
