Dockerfile that attempts to run the app as non-root user. This creates a `node` user & sets permissions on app files. Note you cannot `chown` files in a docker 'volume' during the build process, but you can at runtime (as part of your `CMD`) but in that case you can't use the `USER` command to change the UID before `CMD` runs.

###
# Node.js app Docker file
#
# Some basic build instructions:
# ```
# # you should delete node_modules b/c you don't want that copied during 'ADD'
# docker build -t thom-nic/node-bootstrap .
# # run a shell in the container to inspect the environment (as root):
# docker run --rm -itu root thom-nic/node-bootstrap /bin/bash
# ```
