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.

Discovery Library

You can use the #search method to locate a role, optionally restricted to the environment.

It will fall back to searching the local nodes run_list for roles, so you can have less logic flow in recipes.

host ="any_role",
                        :node => node,
                        :environment_aware => false)


You can use the #all method to locate all nodes with a role, optionally restricted to the environment.

Additional options:

hosts = Discovery.all("base",
                      :node => node,
                      :environment_aware => true,
                      :empty_ok => false,
                      :remove_self => true,
                      :minimum_response_time => false


You can use the #ipaddress method to automatically grab a prioritised ipaddress from a node.

The remote node will be compared against the same node, if any are in any clouds detected by ohai (and they are in the same cloud) the local ipv4 will be returned.

You can optionally supply a type argument specifying which ipaddress you would like.

ipaddress = Discovery.ipaddress(:remote_node => host,
                                :node => node)
local_ipv4 = Discovery.ipaddress(:remote_node => host,
                                 :node => node,
                                 :type => :local)
public_ipv4 = Discovery.ipaddress(:remote_node => host,
                                 :node => node,
                                 :type => :public)
