Support for Raspberry pi 4

[adremides]

Seems like @discordjs/opus doesn't have the binary pre compiled to work with arm64v8.

Some changes in Dockerfile do the magic but image grows a lot due to the need of building tools.

Made an issue in the repo of discordjs/opus: Support for Raspberry pi 4

Dockerfile

FROM arm64v8/node:16-alpine

# Install python/pip
ENV PYTHONUNBUFFERED=1
RUN apk add --update --no-cache python3 && ln -sf python3 /usr/bin/python
RUN python3 -m ensurepip
RUN pip3 install --no-cache --upgrade pip setuptools
RUN apk add --update --no-cache make gcc g++

ENV NODE_ENV production

WORKDIR /home/node

COPY --chown=node:node . .

RUN npm i @discordjs/opus

USER node

RUN npm i

CMD ["npm", "run", "bot"];

docker-compose.yml

version: '3'

services:
  redis:
    container_name: youtube-bot-redis
    image: arm64v8/redis
    sysctls:
      - net.core.somaxconn=1024
    restart: always

  bot:
    image: youtube-bot:latest
    container_name: youtube-bot
    depends_on:
      - redis
    build: .
    restart: always

I'm not very good at Docker or Nodejs, so any improvment in this solution is very welcome!

Bot seems to load well after the corrections but I got an error when I send the /play command. Bot answers "There was a critical error whilst handling your request. Please report this to your admin.".
In the console this error appears:

EDIT: Problem seems to be the use of rejson module instead simple redis (used in the arm64v8 image). This is the error showed if redislabs/rejson image is used instead arm64v8:

Error: getaddrinfo ENOTFOUND redis
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:71:26) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'redis'
}

And that error is because Redis container is not running properly. This is the error, typical of a bad architecture image:

exec /usr/local/bin/docker-entrypoint.sh: exec format error

Solved redis problem... now I have this at play moment:

                                                throw Error('Bad audio resource, cannot continue.');
            ^

EDIT: Now this error solves by install pulseaudio. By the way, I'm using Ubuntu Server in a Raspberry pi 4.
