Build arguments
Two build arguments are required, namely MC_VERSION and FORGE_VERSION. You
can find your required versions here.
Then, you can specify them in the .env file:
MC_VERSION=1.16.4
FORGE_VERSION=35.1.4
Environment variables
The two possible environment variables are XMS and XMX. These specify the
initial RAM & maximum RAM usage respectively. Only XMX is required; XMS is
just set to the same value as XMX if not specified. You must specify them as
a number, e.g. XMS=4. This number represents a quantity of gigabytes.
Mount points
There a three useful mount points defined:
/app/config: this is where all server config files reside, as well as the mods./app/worlds: this is where the world files are stored.
You can mount these directories somewhere in the host file system by specifying
the mount paths in the .env file. These can be both absolute or relative
paths.
Other config variables
The only other config variable is PORT. This specifies on what port your
server will be discoverable over the internet. The default Minecraft port is
25565.
Java flags
I use the Java flags defined
here.
If you don't agree with this decision, you can change the ENTRYPOINT at the
end of the Dockerfile to the following:
ENTRYPOINT java \
-Xms"${XMS:-$XMX}G" \
-Xmx"${XMX}G" \
-jar "$FORGE_JAR" \
--universe /app/worlds \
--nogui
This will only use the flags absolutely necessary, while still allowing you to tweak the memory variables.
