Dockerfile

# This file is used to build the docker image for the server.
# It makes sure to split the build into two stages:
# 1. Build dependencies and cache them.
# 2. Build the executable and copy it into a minimal runtime image.
# For context on the approach see:
# https://stackoverflow.com/questions/58473606/cache-rust-dependencies-with-docker-build
