From f8194176dc4d510b0774c20691daba7dfb3f173d Mon Sep 17 00:00:00 2001 From: Wil Cooley Date: Tue, 20 Mar 2012 22:21:53 -0700 Subject: (#13974) Add predicate functions for interface facts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If one wishes to test if a host has a particular IP address (such as a floating virtual address) or has an interface on a particular network (such as a secondary management network), the facts that provide this information are difficult to use within Puppet. This patch addresses these needs by implementing functions ‘has_ip_address(value)’ and ‘has_ip_network(value)’. These functions look through all interfaces for ipaddress_ and network_ (respectively) having the requested . These functions are implemented on top of a lower-level predicate function, ‘has_interface_with(kind, value)’, which iterates through the interfaces in the ‘interfaces’ fact and checks the facts _ looking for . Additionally, the existence of a particular named interface can be checked for by calling with only a single argument: has_interface_with(interface). A Boolean is returned in all cases. --- .../puppet/parser/functions/has_ip_address_spec.rb | 39 ++++++++++++++++++++++ 1 file changed, 39 insertions(+) create mode 100755 spec/unit/puppet/parser/functions/has_ip_address_spec.rb (limited to 'spec/unit/puppet/parser/functions/has_ip_address_spec.rb') diff --git a/spec/unit/puppet/parser/functions/has_ip_address_spec.rb b/spec/unit/puppet/parser/functions/has_ip_address_spec.rb new file mode 100755 index 0000000..5a68460 --- /dev/null +++ b/spec/unit/puppet/parser/functions/has_ip_address_spec.rb @@ -0,0 +1,39 @@ +#!/usr/bin/env ruby -S rspec +require 'spec_helper' + +describe Puppet::Parser::Functions.function(:has_ip_address) do + + let(:scope) do + PuppetlabsSpec::PuppetInternals.scope + end + + subject do + function_name = Puppet::Parser::Functions.function(:has_ip_address) + scope.method(function_name) + end + + context "On Linux Systems" do + before :each do + scope.stubs(:lookupvar).with('interfaces').returns('eth0,lo') + scope.stubs(:lookupvar).with('ipaddress').returns('10.0.2.15') + scope.stubs(:lookupvar).with('ipaddress_eth0').returns('10.0.2.15') + scope.stubs(:lookupvar).with('ipaddress_lo').returns('127.0.0.1') + end + + it 'should have primary address (10.0.2.15)' do + subject.call(['10.0.2.15']).should be_true + end + + it 'should have lookupback address (127.0.0.1)' do + subject.call(['127.0.0.1']).should be_true + end + + it 'should not have other address' do + subject.call(['192.1681.1.1']).should be_false + end + + it 'should not have "mspiggy" on an interface' do + subject.call(['mspiggy']).should be_false + end + end +end -- cgit v1.2.3
