How to build a fontconfig bundle for adding arbitrary fonts to headless chrome independent of the OS. This is specifically useful for deploying headless chrome to AWS lambda where it is necessary to include fonts for rendering CJK (Chinese, Japanese, Korean) characters into the deployed bundle.

Building fontconfig

Start up a lambda-like docker container:

docker run -i -t -v /tmp:/var/task lambci/lambda:build /bin/bash

Install some dependencies inside the container:

yum install gperf freetype-devel libxml2-devel git libtool -y

easy_install pip

Mac OS X

To check the current limits on your Mac OS X system, run:

Local Kubernetes setup on macOS with minikube on VirtualBox and local Docker registry

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
