Idempotent machine images #420

Open Fodoj opened 9 years ago

Fodoj commented 9 years ago

As far as I can see, machine_image is not recreated only if there a data bag item inside machine_image data bag. But if I upgrade my cookbooks that are used inside this machine image, then I would love image to be rebuilt. Or if add new recipe to this image, let's say

machine_image "web" do
  recipe "my-app::deploy"
end

that builds an image. Then I decide that I want some extra metrics collection to happen:

machine_image "web" do
  recipe "my-app::deploy"
  recipe "metrics::setup"
end

What do you think - is it important that chef would understand this change and rebuild an image or it's feature that is not really required by some reason?

It would have to be an option. Something like

machine_image 'web' do
  recipe "my-app::deploy"
  ephemeral true
end
