Provide a Dockerfile for builds

[ravshansbox]

Currently it's hard to build the font. I've tried both on mac and linux without any success. Would be great to have a docker build.

There will be a browser-based tool for custom build.

Also, in v7, the minimal dependency is foundrytools-cli. I don't think it's too hard to install it.

[ravshansbox]

Installing it is not hard, but in bare ubuntu it is not working

[subframe7536]

Is there any error log?

[ravshansbox]

Yeap, sure. Here it is

What are the exact steps to do this in a fresh ubuntu?

[subframe7536]

hmm... I recommend to create a codespace on variable branch and build the font in it

What are the exact steps to do this in a fresh ubuntu?

In my Debian on WSL, there is no extra step

[ravshansbox]

I'm pretty sure you need to install python and pip at least

[subframe7536]

In codespace:

1. pip install foundrytools-cli
2. python build.py

That's all

[ravshansbox]

Figured out what was missing, it's the python-is-python3 package

[ravshansbox]

So basically, these are the required apt packages python3 python-is-python3 fontforge python3-fontforge

[subframe7536]

Thanks. Docs updated

Also, if one wants to use docker for this, the param --platform=linux/x86_64 should be included on ARM Macs, otherwise linux/arm64 is chosen and some packages won't compile on it
