Jekyll on Docker

This tool provides a container-as-a-binary that will pass every option it is run with to the underlying ephemeral container where Jekyll is really installed.

Requirements

• Docker

Installation

Use make:

usage: make install
       make uninstall

$ make install
docker-compose build
Building jekyll

$

Usage

$ jekyll --version
jekyll 3.8.1
$

Custom gems

If there's a Gemfile in the folder this binary is ran into, bundle install will be executed before anything else – effectively preparing the ephemeral container with a very specific set of gems.

$ cd ~/my_project
$ echo "gem 'pygments.rb', '~> 0.6.3'" >> Gemfile
$ jekyll serve -w
