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 Client 13.
Removal: Chef Client 13
Example
Both lines in the example will cause separate deprecation warnings.
node.chef.server = 'https://my.chef.server'
chef_server = node.chef.server
Remediation
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 Client 14.
Removal: Chef Client 14
Example
node.set['chef']['server'] = 'https://my.chef.server'
node.set_unless['chef']['server'] = 'https://my.chef.server'
Remediation
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'
