Overview

Instances of BootstrapContext are the context objects (i.e., self) for bootstrap templates. For backwards compatability, they must set the following instance variables:

  • @config - a hash of knife’s config values

  • @run_list - the run list for the node to boostrap

    "--version #{chef_version}"
  end
end

#chef_version ⇒ Object

This function is used by older bootstrap templates other than chef-full and potentially by custom templates as well hence it’s logic needs to be preserved for backwards compatibility reasons until we hit Chef 12.
