INF142-Project - Group 31

Mandatory assignment 2 - Group 31

Proposal

• Station client, randomly using UDP / TCP
• Storage server accepting UDP and TCP connections
• MongoDB for storing sensor data
• WebServer for rendering the web page displaying sensor data from MongoDB
• Frontend with some simple Javascript code for fetching data from the server.

Run all containers:

1. docker-compose up
2. Visit localhost:5000 in browser
3. Success

Build new docker images after code modifications:

1. Close current running docker-compose by either interrupting the terminal or docker-compose down
2. Delete old docker images: docker image rm web-server storage-server station -f
3. Rebuild and start: docker-compose up
4. Answer y when asked to replace old containers

Getting started with web-server (local)

1. Run the following command in the root folder:

   pip install -r requirements.txt.

2. Set up a .env file with the following variables in the web-server folder:

   • APP_PORT
   • MONGODB_DATABASE
   • MONGODB_USERNAME
   • MONGODB_PASSWORD
   • MONGODB_HOSTNAME

3. Run the following command python server.py in the web-server folder to start the server.

MVP

• It consists of at least three Python scripts, one for each of the aforementionedprocesses.
• At least one TCP socket is used.
• At least one UDP socket is used.
• The provided script station.py is used by the weather station process to simulate the readings of weather sensors. Note that you only need to import a class from this script. You do not need to understand the code in it.
• The storage server process periodically stores data in a file or database.
• The storage server process provides remote access to the stored data.
• The FMI process(user agent) runs in a CLI and, upon request, displays all the data available in the storage server.

Adding some extras

• [] Requests
• Flask
• Docker (and Docker Compose)
• [] SQL
• MongoDB
• A GUI
