Ruby Jekyll:在gitlab ci管道中使用PDFKit生成文件

我试图用jekyll生成一个静态网站，包括生成每篇文章的pdf文件

这是我的jekyll模块：

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

和注册表的Dockerfile.gitlab.com/thalion59fr/jekyll ci:master image: （基于，稍后我将使用继承创建一个适当的Dockerfile）

我最终通过修改建筑图像解决了这个问题：

  && rm -rf /var/cache/apk/* \

如您所见，我放弃了使用jekyll生成pdf。在“jekyll构建”之前，我使用gimli生成pdf文档。 然后我在posts布局中使用一些流动标记：

<a href="/statics/{{page.path | split: '/' | last | split: '.' | first}}.pdf">download as pdf</a>

xvfb允许wkhtmltopdf无头执行，脚本命令在此执行：

它不是很整洁，但现在就可以了。 我现在必须处理css，但是使用gimli会很容易
