Cackalackycon - Score Processor

Env

We transitioned to doppler to handle secrets, but the first iteration was used with a .env file.

Non Docker

Create virtualenv first

pip install virtualenv
virtualenv -p python3 scoreprocessor
. .\scoreprocessor\Scripts\activate

Install requirements

pip install -r requirements.txt

Run the Processor

With Doppler

doppler secrets set SKIP_METRICS=False
doppler run -- python processor.py --log-config log.ini

Without Doppler

You'll have to set variables prior to running. So either set them inline, or export.

SKIP_METRICS=True python processor.py --log-config log.ini

Build the image

docker build -t score-processor:latest .

Start the container

docker run --name score-processor -e DOPPLER_TOKEN="<token>" --network local-ckc

Stop the container

docker stop score-processor

Remove the container

docker rm score-processor

Access the container

docker exec -it score-processor /bin/bash

Network

To communicate with local otel collector, create a docker network: docker network create local-ckc

Then, run the containers with your network: --network local-ckc

Valid messages

When it's a list of dict, we expect the game key "g" to be the full name of the game When it's a list of list, we expect either an abbreviation or the full name

GAME_ABBREVIATION_MAP = {
    "BO": "Breakout",
    "LA": "Labyrinth",
    "RO": "Asteroids",
