This is a clone off this project: https://github.com/jakerieger/FlaskIntroduction.git, dockerized.

Before:

• How To Run

1. Install virtualenv:

$ pip install virtualenv

2. Open a terminal in the project root directory and run:

$ virtualenv env

3. Then run the command:

$ .\env\Scripts\activate

4. Then install the dependencies:

$ (env) pip install -r requirements.txt

5. Finally start the web server:

$ (env) python app.py

This server will start on port 5000 by default. You can change this in app.py by changing the following line to this:

if __name__ == "__main__":
    app.run(debug=True, port=<desired port>)

After:

1. Install Docker

https://docs.docker.com/engine/install/

3. Run:

$ docker compose up --build

This server will start on port 5000 by default. You can change this in app.py by changing the following line to this:

if __name__ == "__main__":
    app.run(debug=True, port=<desired port>)

Once the containers are running, you can access the API at http://localhost:5000 and the Prometheus dashboard at http://localhost:9090. The /metrics endpoint of the API will expose the metrics that Prometheus can scrape.
