# To use this Dockerfile:
# 1. `docker build . -t mymesa_image`
# 2. `docker run --name mymesa_instance -p 8521:8521 -it mymesa_image`
# 3. In your browser, visit http://127.0.0.1:8521
#
# Currently, this Dockerfile defaults to running the Wolf-Sheep model, as an
# illustration. If you want to run a different example, simply change the
# MODEL_DIR variable below to point to another model, e.g.
# examples/sugarscape_cg or path to your custom model.
# You specify the MODEL_DIR (relative to this Git repo) by doing:
# `docker run --name mymesa_instance -p 8521:8521 -e MODEL_DIR=examples/sugarscape_cg -it mymesa_image`
# Note: the model directory MUST contain a run.py file.

ENV MODEL_DIR=examples/wolf_sheep
