scotthz/cncjs repository overview

Using this image is easier than installing CNCjs⁠ on bare-metal Raspberry Pi.

I run CNCjs as a service using systemd so that CNCjs starts automatically on boot. See below for the simple service file.

The following command line can be used to launch the container when not running as a service. I map port 80 to the container because I have a dedicated Raspberry Pi for CNCjs and don't run anything else on it. I map a folder to /cncjs in the container, though that doesn't do much in normal usage, but in can be useful if you run a shell CLI in the container.

docker run --privileged --rm --detach --volume /home/pi/Desktop:/cncjs --publish 80:8000 scotthz/cncjs:latest

⁠Dockerfile
