This is an Egg for Pterodactyl. It provides support for hosting an Eco server.
In Pterodactyl, click on Import Egg at the page Nests.
Also you'll have to disable throttling in the daemons config /srv/daemon/config as the gameserver creates a lot of messages while generating maps. Also you need to restart wings.
Alternatively you could upload your own map before starting the server.
The Egg uses a custom docker container uploaded by me to the docker hub. The mono docker container shipped with Pterodactyl makes the server crash as libraries are missing.
