问题
I'm trying to generate a static website with jekyll, including the generation of a per article pdf file.
Here is my jekyll module :
require 'pdfkit'
module Jekyll
Jekyll::Hooks.register :site, :post_write do |post|
post.posts.docs.each do |post|
filename = post.site.dest + post.id + ".pdf"
dirname = File.dirname(filename)
Dir.mkdir(dirname) unless File.exists?(dirname)
kit = PDFKit.new(post.content, :page_size => 'Letter')
kit.stylesheets << './css/bootstrap.min.css'
kit.to_file(filename)
end
end
end
Everything is working properly on my workstation, so i suppose there is a problem with my pipeline.
Here is my .gitlab-ci.yml :
stages:
- build
- deploy
build:
image: registry.gitlab.com/thalion59fr/jekyll-ci:master
stage: build
script:
- bundle
- gem list
- bundle exec jekyll build --trace
only:
- master
artifacts:
paths:
- _site/
deploy:
image: registry.gitlab.com/thalion59fr/jekyll-ci:master
stage: deploy
script:
- aero deploy --directory _site
dependencies:
- build
And the Dockerfile of the registry.gitlab.com/thalion59fr/jekyll-ci:master image : (based on this one, I will make a proper Dockerfile with inheritance later)

Thanks for your help ! David

I finally solved the problem by modifying the building-image:
FROM aerobatic/jekyll:0.0.2
MAINTAINER David Vergison <david.vergison@gmail.com>
ADD xvfb-run /usr/bin/
RUN chmod +x /usr/bin/xvfb-run \
&& gem update --system \
&& gem install --no-ri --no-rdoc gimli \
&& apk --update add curl ttf-freefont fontconfig xvfb qt5-qtbase-dev dbus \
&& rm -rf /var/cache/apk/* \
And by installing wkhtmltopdf via the packages manager AFTER the gimli gem :
stages:
- build
- deploy
build:
image: registry.gitlab.com/thalion59fr/jekyll-ci:master
stage: build
script:
- bundle install
- apk add wkhtmltopdf --no-cache --repository http://dl-3.alpinelinux.org/alpine/edge/testing/ --allow-untrusted
- mkdir statics
- cd _posts/
- /usr/bin/xvfb-run -- gimli -o ../statics/
- cd ..
- bundle exec jekyll build --trace
only:
- master
artifacts:
when: on_success
expire_in: 3 days
paths:
- _site/
deploy:
image: aerobatic/jekyll
stage: deploy
script:
- aero deploy --directory _site
dependencies:
- build
As you can see, I gave up using jekyll to generate the pdf. I use gimli to generate pdf documents before the "jekyll build". Then I use some liquid markup in the posts layout :
<a href="/statics/{{page.path | split: '/' | last | split: '.' | first}}.pdf">download as pdf</a>
xvfb is here to allow wkhtmltopdf to be execute headless, and the script comme from here : https://gist.github.com/tyleramos/3744901
It's not realy neat, but it will do for now. I now have to work on the css, but it's going to be easy with gimli.
