Method: Chef::Node#allies

Defined in:
lib/chef-helpers/node.rb

#allies ⇒ Array<Chef::Node>

Node's "allies" are all nodes in the same environment (if the environment is not _default), and nodes specified by allies attribute. The allies attribute - if set - should be an array of node names or node search queries; the named nodes and search results will be added to node's allies.

This is mostly useful when defining firewall or other access rules, to easily limit access to insides of a cluster plus a handful of friendly machines.

Returns:

  • (Array<Chef::Node>) —

    Array of node's "allies".
