Updates to improve docker compatibility

[gdunstone]

firmwareFeatures.js is not added in the dockerfile, this causes the app not to start.

change to Dockerfile:3

ADD config.js firmwareFeatures.js grblStrings.js LICENSE lw.comm-server.service package.json README.md server.js version.txt /laserweb/

Also npm start doesnt seem to work and is actually not even used in the systemd unit.

change to docker_entrypoint.sh:5

nice -n -20 node server.js

Also it would be good to have some info on how to build and run the docker image in the wiki. Just some stuff like using --cap-add=SYS_NICE and --device=/dev/ttyUSB0

I'm a docker noob. Why should someone want to run LW as docker on a raspi, if the app is running natively?

Docker creates a virtualenv encapsulating the requirements (like having all packaged on a blackbox) It's very useful, and should not eat much resources doing so in the same machine is emulating :) El jue., 17 may. 2018 17:18, Claudio Prezzi <notifications@github.com> escribió:
