[ERROR] Failed to auto-install CurseForge modpack

[jakeh042]

I'm trying to set up a server for my partner and I to play on together using a collection of mods that we've found, and the server appears to be running just fine, however when I try to load it I keep getting the "[ERROR] Failed to auto-install CurseForge modpack" notification.

services:
  mc:
    container_name: minecraft-server
    image: itzg/minecraft-server
    tty: true
    stdin_open: true
    ports:
      - "25565:25565"
    environment:
      UID: 0
      GID: 0
      EULA: "TRUE"
      MAX_PLAYERS: 2
      MODPACK_PLATFORM: AUTO_CURSEFORGE
      CURSEFORGE_FILES: "@/cf-mods.txt"
    volumes:
      # attach the relative directory 'data' to the container's /data path
      - ./data:/data

For future reference, provide the full startup logs. The details of the error were further up in the logs.

As for the issue, when using MODPACK_PLATFORM: AUTO_CURSEFORGE then you need to supply a modpack via CF_SLUG etc as described here.

In your case, since you have your own set of mods instead of a modpack you'll also need to declare a specific modloader TYPE instead such as https://docker-minecraft-server.readthedocs.io/en/latest/types-and-platforms/server-types/forge/#neoforge and its VERSION.

Here is an example of what that would look like all together
