Develop your Jekyll project in a Docker container, without installing all the
dependencies on the host.
Or don't.

| Install [Bundler]      | `make bundler`

| Parameter            | Default   | Description
| -------------------- | --------- | --------------------------------------------------
| PROJECT_DIR          | ..        | Jekyll project directory
| RUBY_INSTALL_VERSION | 0.7.0     | ruby-install version
| RUBY_VERSION         | 2.6.5     | Ruby version
| CHRUBY_VERSION       | 0.3.9     | chruby version
| PREFIX               | ~/.local/ | Installation directory for ruby-install and chruby

Set parameter values by passing them to make, i.e.

    make ruby RUBY_VERSION=2.7.0

Examples
--------

### Jekyll in Docker

    make docker/up PROJECT_DIR=../jekyll-project/

This builds two images: `jekyll_base` and `jekyll_project`, and runs a
container, which mounts PROJECT_DIR, and runs Jekyll there.

To rebuild the images (i.e. when you bump dependencies), run

    make docker/build PROJECT_DIR=../jekyll-project/

Bring everything down:

    make docker/down

### Jekyll on the host

    make ruby-install
    make ruby-install/clean
    make ruby
    make chruby
    make chruby/clean
    make bundler
    make dependencies PROJECT_DIR=../jekyll-project/
    make jekyll/serve PROJECT_DIR=../jekyll-project/

Some of these might not work on the first try (you'd need to install some
native dependencies for your gems, use `sudo`, etc.).
