ArrGo - Your humble Sea of Thieves based Discord bot

ArrGo is a Sea of Thieves themed Discord bot written in Go (Golang) and makes heavy use of the fantastic discordgo library.

Requirements

To run your own ArrGo instance, you require a Discord bot token. You can create one in the Discord developer portal

Also the bot uses PostgreSQL database as it's storage for user data. Therefore connectivity to a PgSQL server is required for the bot to operate correctly.

To build the bot from the sources, you need to have Go installed, as well.

Getting started

To get started with your own instance of ArrGo, make sure that you have all required components at hand. Next make sure to select the type of Docker environment you want to run on. Now it's time to set up your config file with the corresponding settings for your database, discord token, etc. As final set, you need to run the SQL migrations, so that bot sets up all required database tables and settings. You can do so by providing the -migrate flag. You are now all set and ready to start your ArrGo instance.

Releases

ArrGo is released as Docker image only. You can find the different branches on its Github Packages page.

Docker

Running the Docker image/container requires the exposure of the /arrgo/etc configuration path from your local storage. This path holds the arrgo.toml configuration file. You can also use the ARRGO_TOKEN environment variable within your Docker environment to pass the discord authentication token.

An example execution could look like this:

$ sudo docker run -ti -e ARRGO_TOKEN=<your discord token> -v /local/path/to/arrgo/etc:/arrgo/etc \
    ghcr.io/wneessen/arrgo:main 

docker-compose

We've also prepared an example docker-compose.yml file for you to integrate with your Docker environment to run the bot without much hassle of configuration

version: "3"
services:
  arrgo:
    image: ghcr.io/wneessen/arrgo:main
    container_name: arrgo
    network_mode: "host"
    restart: always
    environment:
      - ARRGO_TOKEN=<your token here>
    volumes:
      - /var/db/arrgo/etc:/arrgo/etc
      - /etc/localtime:/etc/localtime:ro
    logging:
      driver: local

Configuration

The configuration of the bot is fairly simple. The config file is in the TOML format, so it's really easy to understand. An example congfiguration arrgo.toml.examle is provided with the bot. Most settings are pre-configured with sane defaults, but some configuration (i. e. database settings) needs to be provided by the user.

The configuration is seperated within different sections. The following documentation describes the different sections.

Discord specific confguration

Within the [discord] section there is currently only one optional settings. The token setting specifies the Discord API token for your bot. Instead of providing it via the config file, you can also use the ARRGO_TOKEN environment variable to provide your token. The environment variable has higher importance than the config and therefore will override the token provided in the arrgo.toml

Example:

[discord]
token = "<your discord token>"

Log settings

The [log] section lets you configure the log level the bot is supposed to operrate on. Via the level setting you can choose between the following levels:

• debug
• info
• warn
• error

The bot logs everything in JSON format. The log level defaults to info.

Example:

[log]
level = "info"

Database configuration

The [db] section is mandatory and requires to be filled by the user before running the bot. As described in the requirement section, the bot operates on a PostgreSQL database. The following configuration settings can be provided:

• host: Specifies the hostname or IP address of the PostgreSQL database
• user: Specifies the PostgreSQL username for authentication
• pass: Specifies the PostgreSQL password for authentication
• db: Specifies the PostgreSQL database to connect to
• use_tls: Specifies if the connection to the database should force TLS encryption

Example:

[db]
user = "arrgo"
pass = "superS3cureP4ssw0rd"
db = "arrgo"
host = "pgsql.mynetwork.tld"
use_tls = true

Data specific settings

The [data] section holds settings that are specific to the data processing of the bot. Currently it only holds one setting - the enc_key. All sensitive data in the bot is encrypted on a per-user or per-guild basis. Since the user- and guild encryption keys need to be stored in the database as well, they are encrypted using a global data encryption key.

The enc_key needs to be a 32 character long random string. If none is provided in the configuration, the bot will generate one during startup and provide it to the user, before it then shuts down again. The bot will not start without a valid global encryption key set in the config file.

Example:

[data]
enc_key = "XbM,,I!23BO4AWr6T&@O?F{4gK@%RN!f"

Timer settings

ArrGo performs a couple of background tasks. These are controlled by timers, which can be configured in the [timer] section of the configuration. The bot uses sane defaults, but if you prefer to override some of the settings, you can do so here.

The following timer configurations are currently available:

• flameheart_spam (int): Sets a minimum amount of minutes for the random number generation of the Flameheard SPAM feature
• traderoutes_update (time.Duration): Sets the duration how often the bot should check the traderoutes API for updates
• userstats_update (time.Duration): Specifies the duration that the user should updates the user stats history
• ratcookie_check (time.Duration): The duration how often the bot checks the provided RAT cookies for validity

Example (with default values):

[timer]
flameheart_spam = "60"
traderoutes_update = "12h"
userstats_update = "30m"
ratcookie_check = "5m"

Sea of Thieves specific commands

Any Sea of Thieves related bot command is only available to registered users, as it requires the bot to access the private SoT API with a user specific remote access token (RAT). This token has to be stored in the bot's database and has to be renewed approx. every 14 days (the bot will DM you when your cookie expired).

Getting access to the API

Unfortunately the SoT API does not offer any kind of OAuth2 for authentication - at least not publicly available. Hence we have to use a kind of hackish way to get your access cookie from the Microsoft Live login.

You can either use the SoTBot-RAT-Chrome-Extension or the SoTBot-Token-Extractor (please read the notes in the project before using it) to get a current cookie and store it in the database of the bot. Unfortunately the cookie is only valid for approx. 14 days, so you'll have to renew it every now and then.

The RAT cookie

The RAT cookie grants full access to your account on the Sea of Thieves website. Therefore, even though the cookie is encrypted at rest, before storing your cookie in the bot's DB, please make sure that you know what you are doing. Maybe at some time, RARE decides to offer a apublic API, which offers OAuth2, so we can allow the bot having access to the API data without having to store/renew the cookie.

Automatic user balance tracking

The bot is able to track the users presence state. If a registered user with a valid RAT cookie has their "currently playing" feature activated with Discord and starts playing "Sea of Thieves", the bot will automagically fetch the users current balance and once the user stops playing, repeat the process. The before and after values are then compared and announced in either the guild's official system channel or alternatively in a channel that has been overriden by the guild administrator using the /override announce-channel slash command. By default the summary announcing is disable per guild and has to enabled by the guild administrator using the /config announce-sot-summary enable slash command.

Command documentation

Administrative commands

The bot offers two types of slash commands for configuring your bot on the Discord guild level. The /config command usually allows to set pre-configured enable/disable settings. The /override command allows to override system defaults.

Enable/disable Sea of Thieves user monitoring

The bot is able to monitor if a user plays Sea of Thieves and provide a summary after the play session. By default this feature is disabled, but can enabled guild-wide by an administrative user using the /config announce-sot-summary settings. The possible options are enable and disable
