+# Dockerfile using debian to compile quectocraft
+# Author: Tyler Murphy <tylerm.dev>
+
+# How to run:
+# With the working directory set to the root of this repository,
+# run the following shell command
+# docker build -f Dockerfile -t quectocraft .
+#
+# If you wish to run this in docker compose, it is already set
+# to build the Docker file. Therefore you can just run
+# docker compose up -d
+
+##### Build Environment #####
+
+# Used for building not for deployment
+# This is includes rustc which isnt needed for production
+# Use debian buster because its LTS and stable :3
+FROM rust:buster as builder
+WORKDIR /usr/src/quectocraft

+# Copy over the rust files and source code for quectocraft
+# Cargo.lock is needed because we dont want it updating packages
+# on different peoples system
+COPY ./Cargo.toml ./Cargo.toml
+COPY ./Cargo.lock ./Cargo.lock
+COPY ./src ./src
+
+# Make sure libluajit-dev is installed so that the mlua rust crate
+# can compile
+RUN apt-get update && \
+    apt-get install -y libluajit-5.1-dev && \
+    rm -rf /var/lib/apt/lists/*
+
+# Compile the program in into the containers local bin folder
+RUN cargo install --path .
+
+##### Production Environment #####
+
+# Mininimal container environment while still allowing dependcies
+# to work. Had issues compiling and running on alpine, so we are
+# using debian here.
+FROM debian:buster-slim
+
+# Copy over the the binary from the builder envirnment
+COPY --from=builder /usr/local/cargo/bin/quectocraft /usr/local/bin/quectocraft
+
+# Again make sure libluajit is installed, though we dont need the dev
+# version as headers are only needed when building
+RUN apt-get update && \
+    apt-get install -y libluajit-5.1 && \
+    rm -rf /var/lib/apt/lists/*
+
+# Create the working directory for quectocraft, this is where the plugin folder
