Dockerfile

# This is a multi-stage build file, which means a stage is used to build
# the backend (dependencies), the frontend stack and a final production
# stage re-using assets from the build stages. This keeps the final production
# image minimal in size.

# Stage 1 - Backend build environment
# includes compilers and build tooling to create the environment
