## 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
|
|
```
|
|
|
|
### Mumbler Server Setting
|
|
|
|
To ensure compatibility please edit your murmur configuration file with the following
|
|
|
|
```bash
|
|
opusthreshold=0
|
|
```
|
|
|
|
This ensures all packets are opus encoded and should not cause any compatibility issues if your users are using up to date clients.
|
|
|
|
## Building From Source
|
|
|
|
This project requires Golang to build from source.
|
|
A simple go build command is all that is needed.
|
|
Ensure the opus library is installed.
|
|
|
|
```bash
|
|
go build -o mumble-discord-bridge *.go
|
|
```
|
|
|
