Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Knife Attribute Knife Plugin

Manipulate Chef attributes via Knife

Install & Usage Instructions

knife-attribute

Manipulate Chef attributes via Knife

Installation

Install via rubygems:

gem install knife-attribute

Or for more recent Chef or ChefDK installations:

chef gem install knife-attribute

Usage

To work with attributes of type default, normal or override, use the -t TYPE flag (the default type if unspecified is normal for nodes, and default for all other entity types).

node attribute set

Setting node attributes may be achieved as follows:

knife node attribute set foo.example.org tz 'Australia/Melbourne'

The above would set the foo.example.org node's normal attribute tz to the string Austraila/Melbourne.

You may specify either a regular string, or a JSON structure, ie:

knife node attribute set foo.example.org apache.listen_ports '["80", "443"]' -t override

The above would set the foo.example.org node's override attribute ['apache']['listen_ports'] to the array ["80", "443"].

node attribute get

Getting node attributes may be achieved as follows:

knife node attribute get foo.example.org apache.listen_ports

Use the standard -F FORMAT flag to set the output format for complex data structures.

Unlike other actions, by default the get action will return the combined (effective) value for the attribute, if an attribute type (-t TYPE) is not specified.

knife node attribute get foo.example.org apache.listen_ports -t override -F json

The above would get the foo.example.org node's override attribute ['apache']['listen_ports'] and output it as JSON.

node attribute delete

Deleting node attributes may be achieved as follows:

knife node attribute delete foo.example.org tz

The above would delete the foo.example.org node's normal attribute tz.

knife node attribute delete foo.example.org apache.listen_ports -t override

The above would delete the foo.example.org node's override attribute ['apache']['listen_ports'].
