Simple-Docker-Discord-MCbot

Creating a Discord bot using discord.js to restart a Docker container on the host system involves several steps. Below is a complete guide to set this up, including the necessary code.

Setup Node.js and discord.js:

Setup Node.js and discord.js:

Ensure you have Node.js installed. Then, create a new project and install the necessary dependencies.

Setup & Dependencies

mkdir discord-docker-bot; cd discord-docker-bot

npm init -y

npm install discord.js@14 @discordjs/rest discord-api-types

npm install dotenv js-yaml 

Create a .env file

Create a .env file:

echo "DISCORD_TOKEN='YOUR_BOT_TOKEN'" > .env

This file will store your bot's token securely.

Modify the bot const

change these values according to your needs:

• const dockerComposeFile = '/home/$user/docker-minecraft/docker-compose.yml';
• const dockerContainerName = 'mcserver';
• const YourGuildID = 'YOUR_GUILD_ID';

Run the bot

Execute your bot script using Node.js:

node bot.js

Don't forget !

You need to grab your actual bot key on https://discord.com/developers/applications/ then add in the .env file as shown bellow replace:

DISCORD_TOKEN=YOUR_BOT_TOKEN

'YOUR_GUILD_ID'

with your Discord server ID/bot token

Ensure the bot has the necessary permissions

to create commands, read messages, and add reactions.

Make sure Docker and docker-compose are installed and configured correctly

on the host system where this script runs. Adjust the variables located in bot.js (or requires additional flags.)

TODO

Error Handling

• Wrap parts of code and try to handle potential errors.
• even Better error handling

Command Cooldown

• Implement cooldown for the main restart function to prevent spamming and avoid corruption.
• Implement cooldown for other commands to maintain the bot's performance and prevent user spamming.

Poll Timeout

• Set a timeout for your bot's polls, ending them if no reaction is received within that time.
• Set a countdown before execution/poll closes

Poll Results Verification

• Limit reactions per user to 1 for more accurate poll results.
• Easily configure the number of reactions required

Command Usage Logging

• Implement logging for all command usages to aid debugging.

Command Help

• Create a /help command to provide brief descriptions of all available commands and improve user understanding.

Permissions Check

• Before executing critical commands, check if the user has the necessary permissions. If not, return an error message.

Rate Limiting

• Implement rate limiting on command usage to prevent abuse and overloading your bot.

Embeds

• Utilize Discord Embeds to make bot's responses more visually appealing.
