[chef] What does this `force` option does that is in the apps databag?

[Sachin Sagar Rai < >]

Hi chefians!

In the standard application cookbook's rails recipe, the following is defined.

    deploy_revision app['id'] do

      revision app['revision'][node.chef_environment]

      repository app['repository']

      ......

      action app['force'][node.chef_environment] ? :force_deploy : :deploy

      ssh_wrapper "#{app['deploy_to']}/deploy-ssh-wrapper" if app['deploy_key']

      shallow_clone true

      ......

    end

    

And this values are passed from the apps databag:

    ....

    "force": {

      "production": false, "development": true, "test": false

    },

    ....

    

@sean_horn from Opscode said: `force` feeds into the chef_deploy resource.

But I was not clear enough.

Can someone explain with a use case what does that `feeds into the chef_deploy resource` means?

And what does that `shallow_clone true` does in the above defined `deploy_revision app['id'] do.....` mean?
