fercord

A discord bot written in Rust, for personal use.

Configuration

When running locally/directly

You can specify the location of the config file by setting the CONFIG environment variable (i.e.: CONFIG=$XDG_CONFIG_HOME/fercord/config.toml) or if not specified we look in .config/config.toml in the current working directory.

Example config.toml:

discord_token = "your-bot-token"
database_url = "sqlite://fercord.db"
redis_url = "redis://localhost/"
job_interval_min = 1
shard_key = "c69b7bb6-0ca4-40da-8bad-26d9d4d2fb50"

• discord_token: Your bot token
• databse_url: the url to the database. Currently we only support postgres
• redis_url: the url to the redis instance used to store runtime configuration
• job_interval_min: the interval (in minutes) that the scheduler leaves between runs
• shard_key: a UUID that should be unique per bot instance that is connecting to the same key-value store

Configuration from environment variables

Every variable mentioned above can be overriden from the environment. The correct environment variable prefix is "FERCORD_".

To override your discord token you would set the environment variable FERCORD_DISCORD_TOKEN to your token. Settings set through environment variables take precendence over configuration set via a config file.

Docker

The container has a built-in config.toml stored at /config/config.toml. The only setting set there is job_interval_min (set to 1). If you want to build your own docker image, you can override the location fercord looks for the config file by setting the CONFIG environment variable in the Dockerfile.

This means the following environment variables HAVE to be specified in order for the container to be able to function:

• FERCORD_DISCORD_TOKEN
• FERCORD_DATABASE_URL
• FERCORD_REDIS_URL
• FERCORD_SHARD_KEY

If you want a different job interval, you can specify it through FERCORD_JOB_INTERVAL_MIN.

The sqlite database is placed in the /data directory and called fercord.db. The container exposes /data as a volume, so it will persist between updates etc.

RUST_LOG

The default value for RUST_LOG in the container is info,sqlx::query=warn. You can override this, but if you choose to, please copy the value for sqlx::query.

Any log level lower than that will output the queries that sqlx runs, which might be a security issue.
