Deprecation: Some Attribute Methods (CHEF-4)

We are continuously improving and streamlining the way attributes work in Chef, to make it easier for users to reason about and safely configure their servers.

This page documents many deprecations over the course of many Chef releases.

Method Access

Setting and accessing node attributes has been standardized on “bracket” syntax. The older “method” syntax is deprecated and will be removed in Chef Infra Client 13.

Removal: Chef Infra Client 13


Both lines in the example will cause separate deprecation warnings.

node.chef.server = 'https://my.chef.server'
chef_server = node.chef.server


Convert method syntax to bracket syntax by using brackets to denote attribute names. The code below is identical in function to the example above:

node['chef']['server'] = 'https://my.chef.server'
chef_server = node['chef']['server']

Set and Set_Unless

Setting node attributes with set or set_unless has been deprecated in favor of explicitly setting the precedence level. These methods will be removed in Chef Infra Client 14.

Removal: Chef Infra Client 14


node.set['chef']['server'] = 'https://my.chef.server'
node.set_unless['chef']['server'] = 'https://my.chef.server'


Choose the appropriate precedence level, then replace set with that precedence level.

node.default['chef']['server'] =  'https://my.chef.server'
node.default_unless['chef']['server'] = 'https://my.chef.server'
