How to manage system dependencies when using azk?

Question

I am using azk and my system is dependent on additional packages. I will be able to install them using (since I am using an image based on Ubuntu):

apt-get -yq update && apt-get install -y libqtwebkit-dev qt4-qmake

Can I add these steps to provide? As Azkfile.jsit will look like this:

// ...
provision: [
  "apt-get -yq update",
  "apt-get install -y libqtwebkit-dev qt4-qmake",
  "bundle install --path /azk/bundler",
  "bundle exec rake db:create",
  "bundle exec rake db:migrate",
]

Or is it better to create a new Docker image?

Answer 1

, , , , . , , bundle .

Dockerfile. :

FROM azukiapp/ruby:2.2.2 # or the image you were using previously
RUN apt-get -yq update && \
    apt-get install -y libqtwebkit-dev qt4-qmake && \
    apt-get clean -qq && \
    rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* # Keeping the image as small as possible

Azkfile.js image Dockerfile ( azk docs ):

image: { dockerfile: './PATH_TO_DOCKERFILE' },

, azk start, azk Docker .

. azk Docker, -B azk start.
