Infoblox

Interact with the Infoblox WAPI with Ruby. Use this gem to list, create, and delete host records.

Installation

Add this line to your application's Gemfile:

gem 'infoblox'

And then execute:

$ bundle

Or install it yourself as:

$ gem install infoblox

Usage

Connecting

An instance of the Infoblox::Connection class is necessary:

connection = Infoblox::Connection.new(username: '', password: '', host: '')

Reading

Each resource class implements .all, .find, and #get.

.find

Use find when you don't know what you are looking for or you don't have a _ref saved (see get below). Use _max_results to limit / expand the number of returned results.

# You can find hosts that match a regular expression:
Infoblox::Host.find(connection, {"name~" => "demo[0-9]{1,}-web.domain"})
# => [...]

.all

Show all results (note that this is limited by _max_results). Use this cautiously when you have a large potential set of results.

# Find all networks. Note that this is limited to 1000 objects, as per the 
# Infoblox WAPI documentation. 
Infoblox::Network.all(connection)
# => [...]

# If you want more than 1,000 records, use `_max_results`:
Infoblox::Network.all(connection, _max_results: 7890)

The usage of search parameters is well-documented in the Infoblox WAPI documentation, and this client supports them fully.

#get

Use this when you have saved a reference (_ref) and want to load it later.

host = Infoblox::Host.new(:connection => c, :_ref => ref).get
puts host.name 
# => foo.bar

Searching

You can also search across all Infoblox resource types using the Infoblox::Search resource. The response will contain any number of Infoblox::Resource subclass instances.

result = Infoblox::Search.find(connection, "search_string~" => "webserver-")
# => [#<Infoblox::Host>, #<Infoblox::Ptr>, ...]

Writing and deleting

The resource class instances implement get, post, put, and delete methods, which correspond to the REST verbs supported by the WAPI. For example, here is how to create, update, and delete a network:

# create
network = Infoblox::Network.new(connection: connection)
network.network = "10.20.30.0/24"
network.extensible_attributes = {"VLAN" => "my_vlan"}
network.auto_create_reversezone = true
network.post

# update
network.network = "10.20.31.0/24"
network.put

# delete
network.delete

This pattern applies for interacting with every resource. Supported resources include:

Infoblox::AAAArecord
Infoblox::Arecord
Infoblox::Cname
Infoblox::FixedAddress
Infoblox::Host
Infoblox::HostIpv4addr
Infoblox::Ipv4address
Infoblox::Mx
Infoblox::Network
Infoblox::NetworkContainer
Infoblox::Ptr
Infoblox::Range
Infoblox::Search
Infoblox::Srv
Infoblox::Txt
Infoblox::ZoneAuth

The specific attributes supported by each resource are listed in the source code. Adding a new resource class is easy, and pull requests are encouraged.

Changing IP on an existing host

To change the IP of an existing host, you have to poke around in the ipv4addrs collection to find the one you are looking for. The example below assumes that there is only one ipv4 address and just overwrites it.

host = Infoblox::Host.find(connection, {"name~" => "my.host.name"}).first
host.ipv4addrs[0].ipv4addr = "10.10.10.10"
host.put

Basic CRUD examples

To do basic create/update/delete operations on an a_record/ptr_record set:

Create:

a_record = Infoblox::Arecord.new(
  connection: connection, 
  name:       <fqdn>, 
  ipv4addr:   <ip_address>)
a_record.post

ptr_record = Infoblox::Ptr.new(
  connection: connection, 
  ptrdname:   <fqdn>, 
  ipv4addr:   <ip_address>)
ptr_record.post

Update:

a_record = Infoblox::Arecord.find(connection, {
  name:     <fqdn>, 
  ipv4addr: <ip_address>
}).first
a_record.name     = <fqdn>
a_record.ipv4addr = <ip_address>
a_record.view     = nil
a_record.put

ptr_record = Infoblox::Ptr.find(connection, {
  ptrdname: <fqdn>, 
  ipv4addr: <ip_address>
}).first

ptr_record.ptrdname = <fqdn>
ptr_record.ipv4addr = <ip_address>
ptr_record.view = nil
ptr_record.put

Delete:

a_record = Infoblox::Arecord.find(connection, {
  name:     <fqdn>, 
  ipv4addr: <ip_address>
}).first
a_record.delete

ptr_record = Infoblox::Ptr.find(connection, {
  ptrdname: <fqdn>, 
  ipv4addr: <ip_address>
}).first
ptr_record.delete

Next Available IP

The Infoblox::Network and Infoblox::Range objects support the next_available_ip WAPI function:

network = Infoblox::Network.find(connection, 
                                 network: '10.21.0.0/24').first
puts network.next_available_ip.inspect
#=> ["10.21.0.22"]

Note that this function does not work on a resource that has not been created. In other words, if you want to get the next available IP for a given network segment, you have to create that segment beforehand. See the CRUD examples above.

Extensible Attributes

Extensible attributes are supported in this client. It should be noted that in WAPI versions before 1.2, the field is named "extensible_attributes", whereas in version 1.2 and later, it is named "extattrs".

Infoblox Version Compatibility

This gem is known to be compatible with Infoblox versions 1.0 through 2.0. While Infoblox claims that their API is backwards-compatible, one caveat remains with the Extensible Attributes (see elsewhere in this document). Some features are only available in newer versions (such as FixedAddress and AAAARecord). To set your version, use the WAPI_VERSION environment variable. For example:

WAPI_VERSION=2.0 ruby my_script.rb

Ruby Version Compatibility

This gem is tested against Ruby versions 1.8.7, 1.9.3, 2.1.6, JRuby-head, and JRuby in 1.9 mode.

Development / testing

First, clone and bundle:

bundle install

To run the tests:

rspec

To run the integration tests (you will be prompted for your Infoblox credentials):

INTEGRATION=true bundle
INTEGRATION=true rspec

Please note that the integration tests do not work in Ruby 1.8.7, but the unit tests function normally.
