How to serve a custom HTTPS domain on GitHub Pages with CloudFlare: *FREE*, secure and performant by default

Instructions

CloudFlare is an awesome reverse cache proxy and CDN that provides DNS, free HTTPS (TLS) support, best-in-class performance settings (gzip, SDCH, HTTP/2, sane Cache-Control and E-Tag headers, etc.), minification, etc.

  4. From the CloudFlare settings for that domain, enable HTTPS/SSL and set up a Page Rule to force HTTPS redirects. (If you want to get fancy, you can also enable automatic minification for text-based assets [HTML/CSS/JS/SVG/etc.], which is a pretty cool feature if you don't want already have a build step for minification.)

set -e, -u, -o, -x pipefail

The set lines

  • These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
  • With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.
  • set -euxo pipefail is short for:
set -e
set -u
