# Mumble Discord Bridge
Mumble Discord Bridge is an open source Go application to bridge the audio between Mumble and Discord.
It was built with the hope that people can continue to use the voice application of their choice.
## Usage
Several configuration variables must be set for the binary to function correctly.
All variables can be set using flags or in the environment.
The binary will also attempt to load .env file located in the working directory.
```bash
Usage of mumble-discord-bridge:
-discord-cid string
DISCORD_CID, discord cid
-discord-gid string
DISCORD_GID, discord gid
-discord-token string
DISCORD_TOKEN, discord bot token
-mumble-address string
MUMBLE_ADDRESS, mumble server address, example example.com
-mumble-password string
MUMBLE_PASSWORD, mumble password, optional
-mumble-port int
MUMBLE_PORT mumble port (default 64738)
-mumble-username string
MUMBLE_USERNAME, mumble username (default "discord-bridge")
```
## Setup
### Creating a Discord Bot
A Discord bot is required to authenticate this application with Discord.
The guide below provides information on how to setup a Discord bot.
[Create a Discord Bot](https://discordpy.readthedocs.io/en/latest/discord.html)
Individual Discord servers need to invite the bot before it can connect.
### Binary
Prebuilt binaries are available.
```bash
curl -s https://api.github.com/repos/stieneee/mumble-discord-bridge/releases/latest | grep "mumble-discord-bridge" | grep "browser_download_url" | cut -d '"' -f 4 | wget -qi -
```
### Docker
This project is built and distributed in a docker container.
A sample docker command can be copied from below.
This service command will always attempt to restart the service due to the `--restart=always` flag even when the server is restarted.
For testing purposes it may be best to remove the restart flag.
Replace the environment variables with variable for the desired mumble server, discord bot and discord server/channel.
```bash
# Sample for testing
docker docker run -e MUMBLE_ADDRESS=example.com -e MUMBLE_PASSWORD=optional -e DISCORD_TOKEN=TOKEN -e DISCORD_GID=GID -e DISCORD_CID=CID stieneee/mumble-discord-bridge
# Run as a service
docker docker run -e MUMBLE_ADDRESS=example.com -e MUMBLE_PASSWORD=optional -e DISCORD_TOKEN=TOKEN -e DISCORD_GID=GID -e DISCORD_CID=CID --restart=always --name=mumble-discord-bridge -d stieneee/mumble-discord-bridge
# Stop the service
docker stop mumble-discord-bridge && docker rm mumble-discord-bridge
```
## Building From Source
