Dockerize suggestion

[yangsungtze]

Great work!!!
As different users may have varying environments and package versions, using a Dockerfile to containerize the project is recommended.
The built image uses about 600MB of disk space.
I've tested it with one of the sites personally and leave here for reference.

Dockerfile

FROM python:3.11-slim

WORKDIR /app

RUN apt-get update && apt-get install -y \
    build-essential \
    #libffi-dev \
    #libssl-dev \
    && rm -rf /var/lib/apt/lists/*

COPY . .

RUN pip install --no-cache-dir -r requirements.txt

ENTRYPOINT ["python", "subtitle_downloader.py"]

Build
docker build -t subtitle-downloader .

Execute

docker run -rm \
  -v "$PWD/cookies:/app/cookies" \
  -v "$PWD/downloads:/app/downloads" \
  subtitle-downloader \
  "<URL>" \
