Enhancement - DCCB as Docker Container

[fahrenhe1t]

It would be cool if the DiscordCurrentlyCastingBot was created as a Docker container. Easy to manage port access and configuration. Should have the ability to set up a bind volume so database and config is stored on host machine, and is retained between reboots and upgrades. Thanks for your consideration!

Sounds like a good excuse for me to finally get off my duff and learn how to Docker (:
I'll certainly look into it!

I got DiscordCurrentlyCastingBot to work as a Docker container on my home server. I cloned your project to a folder, and filled out the .env with my server/channel info. Then I use this Dockerfile to create the Docker image:

FROM python:3.7.13-alpine3.16

LABEL Maintainer="dopeghoti"

WORKDIR /opt/DiscordCurrentlyCastingBot/

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

COPY bot.py ./
COPY channeldb.py ./
COPY currentlycastingbot-pm2.json ./

CMD [ "python", "./bot.py" ]

Then I build the docker image with: docker build -t discordcurrentlycastingbot:1.1 .

Then I created a docker-compose.yml file to run it. The environment variables in the docker-compose file get passed to the container from the .env file the user creates in the same folder:

---
version: "3"
services:
  dccb:
    image: discordcurrentlycastingbot:1.1
    container_name: discordcurrentlycastingbot
    environment:
      PUID: 1000
      PGID: 1000
      TZ: US/Mountain
      DISCORD_TOKEN: "${DISCORD_TOKEN}"
      DISCORD_GUILD: "${DISCORD_GUILD}"
      DISCORD_PREFIX: "${DISCORD_PREFIX}"
      DISCORD_MONITOR: "${DISCORD_MONITOR}"
      DISCORD_CONTROL: "${DISCORD_CONTROL}"
      TWITCH_CLIENTID: "${TWITCH_CLIENTID}"
      TWITCH_SECRET: "${TWITCH_SECRET}"
      CHANNELS: "${CHANNELS}"
      WATCH_LENGTH: "${WATCH_LENGTH}"
    volumes:
      - ./config/${CHANNELS}:/opt/DiscordCurrentlyCastingBot/${CHANNELS}
    restart: unless-stopped

It maps the database to a bind volume so the data persists between restarts.
Then I run the docker container, and it's verified working on my end: docker compose up -d --force-recreate

Maybe you could create the official image on your end and upload it to the github container repo (ghcr.io) or hub.docker.com?

Thanks for this! I'll fiddle around with it and do a little testing, and if it flies as well as I imagine it will, shall incorporate this.
