Figure out how to dockerize a Python app

[zmoog]

I am experimenting with a personal Discord bot, running it with tmux on my NUC server. Now I want to extend the bot capabilities and run it as container.

I want to run the bot as a container in Docker, and later K8s.

Here are a couple of interesting resources:

• https://docs.docker.com/language/python/containerize/
• https://www.docker.com/blog/how-to-dockerize-your-python-applications/

The multi-step tutorial https://docs.docker.com/language/python/containerize/ seems the best option, but today I will follow the lazy path and follow along the youtube video embedded in https://www.docker.com/blog/how-to-dockerize-your-python-applications/

Using https://github.com/zmoog/dolores

# Dockerfile
FROM python:3.12

ADD README.md .
ADD setup.py .
ADD dolores dolores
ADD .env .

RUN pip install -e '.[test]'

CMD ["dolores", "run"]

docker build -t dolores .

I had to disable the Trello cog because the trellokit package is not available on PyPI:

With the Dockerfile above, I am able to run dolores in a Doceker container.

There are multiple open questions:

• How to properly handle secrets (including .env is not an option).
• How to set up logs.
