Example .env

JAVA_VERSION=17-jre-focal           #Select Java version
SERVER_NAME=mcserver                #Specify container name
VOLUME_PATH=./server                #Specify local path to files
#LINK=                              #Download server.jar from link (comment or leave empty if you will not use it)
TYPE=papermc                        #Select server type: vanilla or papermc
VERSION=1.19.2                      #Select version e.g. 1.19.2
UID=1000                            #Specify the UID of user inside container
GID=2000                            #Specify the GID of user inside container (usually same as UID)
MINMEMORY=1G                        #Specify initial memory (-Xmx)
MAXMEMORY=2G                        #Specify maximum memory (-Xms)
PORT=25565                          #Specify server port

If you want to use custom .jar file you need to place your server.jar inside /server directory and set TYPE to custom

TYPE=custom

VERSION, LINK will not work.

If you want to use forge put download link and change TYPE to forge

LINK=https://maven.minecraftforge.net/net/minecraftforge/forge/.../forge-...-installer.jar
TYPE=forge

VERSION doesn't matter.

If you don't create an .env file the default value of variables will be used (via docker-compose.yaml)

JAVA_VERSION=17-jre-focal
VOLUME_PATH=./server
LINK=
TYPE=papermc
VERSION=1.19.2
UID=1000
GID=2000
MINMEMORY=1G
MAXMEMORY=2G
PORT=25565
