An egg used to run Dragonfly inside of Pterodactyl.
Dragonfly is a Minecraft Bedrock Edition server software written in Go. More information can be found on their GitHub repository and their Discord server
Just import the egg.json file into your Pterodactyl panel and you're good to go! The script and Docker image will be automatically updated on each server start.
My egg implementation is clearly not the best I could've written, but it works. Feel free to open a pull request fixing what you think has to be fixed.
