# In your recipe, do this at the top to monkeypatch the service resource the way we want:

Chef::Resource::DockerService.class_eval do
  property :consumed_resources_updated, Boolean

  def consumes(resource)
    subscribes :consumed_resource_updated, resource, :immediately
    subscribes :run, resource
  end

  action :consumed_resource_updated do
    new_resource.consumed_resources_updated true
  end
  
  module NewCreateAction
    def action_create
      super
      new_resource.reset_property(:consumed_resources_updated)
    end
  end
  # This puts NewCreateAction::action_create as the first thing called, and super() == DockerContainer::action_create
  action_class.prepend NewCreateAction
end

# And then change subscribes to depends_on in your recipe:
directory '/files'

template '/files/some_config.ini' do
  variables(foo: node['bar'])
  action :create
end

template '/files/another_config.ini' do
  variables(foo: node['biz'])
  action :create
end

docker_image 'some_image' do
  tag node['external']['data']
  action :pull_if_missing
end
docker_container 'some_container' do
  tag node['external']['data']['tag']
  port node['external']['data']['port']
  command 'my_program'
  binds "/files:/etc/myprogram/conf.d"
  consumes 'docker_image[some_image]'
  consumes 'template[/files/some_config.ini]'
  consumes 'template[/files/another_config.ini]'
  action :run
end
