An Elixir Discord bot made with Nostrum for playing audio from various sources in voice channels.
When run in a dev environment, the app expects a bot token to be provided in a .env file in the following format: DISCORD_BOT_TOKEN="TOKEN_HERE". You can add your bot token to the .env.example file and rename it to .env.
Next you just need to build the Docker image and run it. Use docker build -f Dockerfile.dev . to build the image in a dev environment where it is receiving the bot token from the .env file. Once built, run it with docker run -it IMAGE_ID_HERE. Since the Dockerfile.dev file builds the image with a default command to run the app in an iex session, the -it arguments should be used in the docker run command to keep the container open so you can interact with it. If this behavior is undesirable then you can change the line CMD ["iex", "-S", "mix"] of the Dockerfile.dev file to be CMD ["mix", "run", "--no-halt"] instead.
If the bot isn't responding to message commands, ensure privileged gateway intents are enabled for the application in your Discord developer portal.
The bot expects commands to be given via message events rather than slash commands. Commands it listens for are:
!ping- Responds with "pong".!summon- Will find the voice channel the user sending the command is in and joins the channel.!leave- Will leave the voice channel it is connected to.!play URL_HERE- Will attempt to play the audio from the given URL. The URL can be any that ffmpeg can read. E.g.!play music/my favorite song.mp3will play the filemy favorite song.mp3if it exists at that path, and!play http://streams.ilovemusic.de/iloveradio10.mp3will attempt to play the audio from that HTTP stream.!stream URL_HERE- Will attempt to stream the audio from the given livestream URL using streamlink. E.g.!stream twitch.tv/day9tvwill attempt to stream the audio from Day9tv's Twitch channel.!stop- Will stop playback.!pause- Will pause the playback.!resume- Will resume the playback.
