Dockerfile

#################
#
# Because Composer is organized as a monorepo with multiple packages
# managed by yarn workspaces, our Dockerfile may not look like other
# node / react projects. Specifically, we have to add all source files
# before doing yarn install due to yarn workspace symlinking.
