dockerized_wkhtmltox

dockerized wkhtmltox for use in dockerized rails projects

why do you need sutch a thing?

Current ruby image (which is usually used for dockerized rails projects) is built debian version which does not play nicely with wkhtmltox, e.g. if you want to generate some image (*.png, *.jpg, etc.) from your Rails app, you will usually find that gem 'imgkit' is the tool to use, but it depends on wkhtmltox which wont be happy inside container (some incompatible jpeg libraries at time of creation) created from available ruby image.

temporary solution - this docker image

the most enduring kind of solutions - temporary one...

add this line to your Dockerfile around same time when you create your application folder:

# make direcory to mount wkhtmltox bin files
RUN mkdir /wkhtmltox

2nd step

modify this snippet into your docker-compose.yml:

version: '3'
services:
  web:
    build: .
    volumes:
      - wkhtmltox-volume:/wkhtmltox

  wkhtmltox:
    image: martinskruze/dockerized_wkhtmltox
     volumes:
       - wkhtmltox-volume:/wkhtmltox_instalation/wkhtmltox/bin

volumes:
  wkhtmltox-volume:

3rd step

add file config/initializers/imgkit.rb:

IMGKit.configure do |config|
  config.wkhtmltoimage = '/wkhtmltox/wkhtmltoimage'
end
