Constructor Details

#initialize(cookbooks, opts = {}) ⇒ CookbookUploader

Creates a new CookbookUploader. ===Arguments:

  • cookbooks::: A Chef::CookbookVersion or array of them describing the cookbook(s) to be uploaded
  • path::: A String or Array of Strings representing the base paths to the cookbook repositories.
  • opts::: (optional) An options Hash ===Options:
  • :force indicates that the uploader should set the force option when uploading the cookbook. This allows frozen CookbookVersion documents on the server to be overwritten (otherwise a 409 is returned by the server)
  • :rest A Chef::ServerAPI object that you have configured the way you like it. If you don't provide this, one will be created using the values in Chef::Config.
  • :concurrency An integer that decided how many threads will be used to perform concurrent uploads
