Dockerfile

# This is an example Dockerfile showing how it's possible to install Klipper in Docker.
# IMPORTANT: The docker build must be run from the root of the repo, either copy the
# Dockerfile to the root, or run docker build with "-f", for example:
#       docker build . -f scripts/Dockerfile -t klipper
# Note that the host still needs to run Linux to connect the printers serial port to
# the container.
# When running, the serial port of your printer should be connected, including an
# argument such as:
#       --device /dev/ttyUSB0:/dev/ttyUSB0
# It's also required that your control program (eg: OctoPrint) be included in the same
# container as Docker does not allow sharing of the virtual serial port outside the
# container.
# The config should be in a file named "printer.cfg" in a directory mounted at:
#       /home/klippy/.config/
# For more Dockerfile examples with Klipper (and Octoprint) see:
# https://github.com/sillyfrog/OctoPrint-Klipper-mjpg-Dockerfile
