Node 6.2.2 & node.bcrypt.js

When using bcrypt with this image you may run into a problem if you are mounting your local node_modules folder into your docker container. There may be times when you need to recompile C++ addons (which bcrypt has). So, to do this make sure that before your container starts executing code to run npm rebuild link.

I do this by building my container and then execing into it. I then manually run npm rebuild as I haven't found a better way to do this yet.

I hope this saves somebody else the hour I wasted trying to figure this out.

Edit
So an easier solution for docker compose is command: bash -c "npm rebuild && npm start" assuming npm start kicks off your server. This same method can be applied to a Dockerfile or the command line.

Edit2
Another, albeit uglier, solution is to mount the Host machines g++ compiler:

/usr/lib/x86_64-linux-gnu/:/usr/lib/x86_64-linux-gnu/

No repository file or test is named. Review the documentation and Dockerfile or Docker Compose entry points for the Node 6.2.2 image, then verify the documented bcrypt workaround by running npm rebuild before npm start; done means the guidance clearly explains the mounted node_modules case.
