# For development, we will yarn install on each container start.
# This ensures that we use our Docker development .yarnrc config
# and get any add/changed dependencies without needing a full rebuild.
#
# We are copying in a .yarnrc file that is specific to running within Docker.
# Thus, we don't want it in the main repo because it breaks yarn on the host
# machine. We also don't want it in APP_SOURCE_DIR where docker-compose will
# link in host files, so we create it as the user-level config.
# Note that this will be copied in for a prod build, too, but since
# we already ran yarn install above, it doesn't matter.
