# The Dockerfile for this project is split into 5 layers.
# - Base:     The base image
# - System:   System package installation
# - Compile:  Custom compilation and installation
# - Packages: Application packages (e.g. npm, pip etc)
# - App:      Task runs and application prep
# The order of the layers is based on which parts are likely to be
#   modified the most.
# The project source is added in the App layer so as not to invalidate
#   the Dockerfile cache.
