scfbuild with Docker

[b-g]

This is to document how to use scfbuild with Docker.

Add a Dockerfile with (to the folder containing scfbuild):

FROM ubuntu:18.04
RUN apt-get update && apt-get upgrade -y
RUN apt-get install python-pip -y
RUN pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org fonttools
RUN pip install --trusted-host=pypi.org --trusted-host=files.pythonhosted.org pyyaml
RUN apt-get install fontforge python-fontforge -y

In terminal:

# Create container; named "openmoji" (could be any other name):
$ docker build -t openmoji .

# Share folder between host computer and docker container
# Run bash "inside" of the container (think of it as being logged in to remote server)
$ docker run --interactive --tty --rm --volume "$PWD":/wd --workdir /wd "openmoji:latest" bash

# Now you can run scfbuild to create a colorfont with the contents of the shared folder e.g.:
$ bin/scfbuild -c scfbuild.yml

@13rac1 Thanks for the hints! Worked nearly out of the box :) Happy to do a PR documenting this ... if helpful.
