# In general, we want to copy files in order of least -> most changed for layer caching reasons.

# - Copy in LICENSE so that people can see it if they explore the image contents
COPY LICENSE .
# - Copy in the production config generation script
COPY create_config_prod.js .
# - Copy in the service info generator
COPY create_service_info.js .
# - Copy in the entrypoint, which writes the config file and starts NGINX
COPY run.bash .
# - Copy in package.json to provide version to scripts
COPY package.json .
# - Copy webpack-built source code from the build stage to the final image
#    - copy this last, since it changes more often than everything above it
#    - this way we can cache layers
