FTB Modpacks

A generic service to pull FTB modpacks from api.feed-the-beast.com. There are 2 ways to install a server through this service. The first method only requires you to know the modpacks name and (optionally) version. The second method requires you to know the id for the modpack and (optionally) version in the api.

Method 1 (Recommended)

FTB_SEARCH_TERM: the modpack name to query for, must be at least 3 characters long. EX: for FTB: Interactions you would do "interactions".
FTB_VERSION_STRING: the string version that you want to install. Leave blank to install latest stable release. EX: for FTB: Interactions 2.0.2, you would put "2.0.2".

Method 2

FTB_MODPACK_ID: the id that directs to the modpack in the api. EX: for FTB: Interactions the id would be "5". https://api.feed-the-beast.com/v1/modpacks/public/modpack/5
FTB_MODPACK_VERSION_ID: the version id in the api. Leave blank to install latest stable release. EX: for FTB: Interactions 2.0.2 the id is "86". https://api.feed-the-beast.com/v1/modpacks/public/modpack/5/86

NOTE Not all FTB packs come with a server.properties file, due to this the server.properties file may not get updated with the correct ip address and port at first launch. Please restart the server after first launch to fix this.

Neoforged

If you have trouble using an neoforge pack, make sure to select the latest java.

Install Script

#!/bin/ash
# Generic FTB Server Installation Script
#
# Server Files: /mnt/server
# MODPACK_VERSION = version of the modpack, set in variables
# i.e MODPACK_VERSION=1.5.0
# MODPACK_URL = url base of the pack, set in variables, hardcoded
# i.e https://www.feed-the-beast.com/projects/ftb-revelation/files
# MODPACK_URL=ftb-revelation

## Correcting for bad variables
GETPACK=$(echo ${MODPACK_URL} | cut -d "/" -f 5 )
echo -e "\n The pack being downloaded is $GETPACK \n"

## Getting the Base URL
BASEURL=https://www.feed-the-beast.com/projects/${GETPACK}/files
echo "The base URL is ${BASEURL}"

## This is meant to get the pack ID that is unique and not exactly clear 


if [ -z "${MODPACK_VERSION}" ] || [ "${MODPACK_VERSION}" == "latest" ]; then
    ID=`curl -sl ${BASEURL} | grep -i -A9 'title="release"' | grep -i -o 'href=".*"' |  cut -d "/" -f5 | sed s/\"//g`
    echo "ID: ${ID}"
else 
    ID=`curl -sl ${BASEURL} | grep -i -A9 "${MODPACK_VERSION}" | grep -m1 -oE 'href="[^\"]+"' | cut -d "/" -f5 | grep -oE [0-9]+`
    echo "ID: ${ID}"
fi

SECONDURL=${BASEURL}/${ID}
echo "SECONDURL: ${SECONDURL}"

GOOD_ID=`curl -sl ${SECONDURL} | grep -i server | grep -Eo 'href="[^\"]+"' | grep -o -E "[0-9]+" | tail -1`
echo "GOOD_ID: ${GOOD_ID}"

DL_URL=${BASEURL}/${GOOD_ID}/download
echo "Download_URL: ${DL_URL}"

cd /mnt/server

echo "Executing curl -L ${DL_URL} -o $GETPACK.zip"
curl -L ${DL_URL} -o $GETPACK.zip

unzip ${GETPACK}.zip

rm -rf ${GETPACK}.zip

echo "Running FTBInstall.sh"
if [ -f ./FTBInstall.sh ]; then
    sh ./FTBInstall.sh
else
    echo -e "No FTBInstall script found. Assumeing it's not needed."
fi


## install end
echo "-----------------------------------------"
echo "Installation completed..."
