Method: Chef::Node#namespace

Defined in:

lib/chef/sugar/node.rb

#namespace(*args, &block) ⇒ nil

Dynamically define the current namespace. Multiple namespaces may be nested.

Examples:

Define a simple namespace

namespace 'apache2' do
  # ...
end

Define a nested namespace

namespace 'apache2', 'config' do
  # ...
end

Define a complex nested namespace

namespace 'apache2' do
  namespace 'config' do
    # ...
  end
end

Define a namespace with a custom precedence level

namespace 'apache2', precedence: normal do
  # Attributes here will use the "normal" level
end

Define different nested precedence levels

namespace 'apache2', precedence: normal do
  # Attributes defined here will use the "normal" level

  namespace 'config', precedence: override do
    # Attributes defined  here will use the "override" level
  end
end

Parameters:

• args (Array) —

  the list of arguments (such as the namespace and precedence levels) the user gave

• block (Proc) —

  the nested evaluation context

Returns:

• (nil) —

  to prevent accidential method chaining if the block isn’t closed
