The Q™

The Q is a Discord bot, a wildly overengineered Rust monorepo, a probably-not-necessary set of Protobuf tools, and most importantly the culmination of years of “we should have a Discord bot that _____” messages in the group chat. It doesn’t do anything particularly useful but it does do quite a few fun things, and by the gods it looks good doing ‘em.

Installation

There are several ways to run The Q. It can be used as a binary or built as a container, and it also comes packaged with a complementary docker-compose.yml to get log ingest and a dashboard with Grafana and Loki.

As a Binary

To build just the binary for the bot, run:

$ cargo build --release --bin the-q

The executable will be located at target/release/the-q and ready for action.

As a Container

To build a containerized version of the bot and tag it with the-q:latest, run:

$ docker build --target bot -t the-q/latest .

(You can replace docker with podman if you so desire.)

Running the container is a little trickier than simply running the binary, but still straightforward, as described below.

With Docker Compose

Starting the services defined in docker-compose.yml will build the container automatically, so no initial setup is required. However, if you would like to perform the build step separately, simply run the following:

$ docker-compose build

Usage

Once installed the bot can simply be started by running the executable or container and providing a Discord API token. This can be done as a command-line argument or as an environment variable (including within a .env file). To see all available command-line flags (and their corresponding environment variables) run the-q --help.

Loading the Environment

To load the Discord API token into the bot’s environment, create a file named .env.local and add the following to it, replacing MY_API_KEY with your actual API token:

DISCORD_TOKEN=MY_API_KEY

If you don't yet have an API token, check out Discord's getting started tutorial for info on how to create a bot user and add it to your servers.

Running the Binary

If you built The Q as a standalone binary, then starting the bot is as simple as running target/release/the-q.

NOTE: .env, .env.prod, and .env.local must be within the current working directory when you run the executable, otherwise the bot will silently skip loading them.

Running the Container

The containerized version of the bot will automatically run the binary inside the container if the container is run with no arguments. The .env and .env.prod files from the repository are built into the container, and loading .env.local can be done with the --env-file flag like so:

$ docker run --env-file .env.local the-q

If you wish to pass command-line arguments to the container, you must invoke the binary directly:

$ docker run the-q bin/the-q --my-flags

Running with Docker Compose

To provision the Grafana container, you will need to pass two environment variables to docker-compose: GF_USER and GF_PASSWD. These can be passed to docker-compose any number of ways, but as an example the repository provides a shell script compose.sh that loads them from a file. To use the script, create a file directly inside the repository root named .env.compose and add the following to it:

GF_USER=admin
GF_PASSWD=admin

Be sure to replace admin with a secure username and password. Then, simply invoke the script to run docker-compose:

$ ./compose.sh up -d
