Mapcrafter Docker Image

Mapcrafter (Github) packed into a Docker image, so you can run it without having to install anything but docker itself.

Run it using something like this:

docker run -it --rm \
    -v /var/lib/minecraft/world:/minecraft_world \
    -v /var/lib/mapcrafter:/map \
    t9t9t/mapcrafter -b -j2 -c /map/mapcrafter.conf

You can also use it without --rm and with --name=mapcrafter, then you only have to use docker start -ai mapcrafter in the future to execute it using the same settings.

You would use a config file like this (which would be located at /var/lib/mapcrafter/mapcrafter.conf):

output_dir = /map/output

[global:map]
world = myworld
rotations = top-left top-right bottom-right bottom-left
water_opacity=0.5
texture_dir=/map/textures

[world:myworld]
input_dir = /minecraft_world
default_zoom = 6
default_view = 362,-174,64

[map:map_myworld]
name = Overworld

[map:map_myworld_night]
name = Overworld - Night
render_mode = nightlight

[map:map_myworld_topdown]
name = Overworld - Top-down
render_view = topdown

In this particular example, the host directory /var/lib/minecraft/world holds the Minecraft world data, which is mounted as a volume inside the container on /minecraft_world which is in turn specified as the input_dir of the world. The directory /var/lib/mapcrafter on the host machine contains mapcrafter related data, in particular the output directory where the generated map will be stored, a textures directory containing custom textures, and the configuration file itself (mapcrafter.conf).
