Bind DDNS

Description

Install and configure ISC Bind https://www.isc.org/downloads/bind/ with
full Dynamic DNS support.

On client side, install nsupdate, provide a generic provider and a recipe
to update DNS entries.

Requirements

Cookbooks and gems

Declared in [metadata.rb](metadata.rb) and in [Gemfile](Gemfile).

Platforms

  • RHEL Family 7, tested on Centos

Note: it should work fine on Debian 8 it is currently not tested.

Usage

Easy Setup

Add recipe[bind-ddns::server] in your run-list to install and configure
Bind. Configuration will be fetched from attributes options, zones and
keys.

To add a client, add recipe[bind-ddns::client]. nsupdate recipe will
update all records defined in records.

To see an example, look at [.kitchen.yml](.kitchen.yml).

Test

This cookbook is fully tested through the installation of a server and a client
in docker hosts. This uses kitchen, docker and some monkey-patching.

If you run kitchen list, you will see 2 suites, Each corresponds to a different
server:

  • server-ddns-centos-7: Bind server
  • client-ddns-centos-7: DNS client with nsupdate

For more information, see [.kitchen.yml](.kitchen.yml) and [test](test)
directory.

Attributes

Configuration is done by overriding default attributes. All configuration keys
have a default defined in [attributes/default.rb](attributes/default.rb).
Please read it to have a comprehensive view of what and how you can configure
this cookbook behavior.

Note: for fields needing an IP address, it is possible to set an interface
name, which will be resolved to its first non-local address.

Specific configuration (client or server)

To allow clients and servers to share a same role, it is possible to define
specific configuration keys applicable to one of the status (client or server).

Specific configurations can be any of the attributes defined in
[attributes/default.rb](attributes/default.rb) but in either "client-config"
or "server-config" sub-tree.

A node is declared as server if its FQDN is included in attribute
"['bind-ddns']['servers']" defined as an array. Else, it is considered
as a client.

Recipes

default

Call init and then, following the node status, call client or
server recipe.

init

Determine if the current machine is a server or a client. Write the result
in "run_state['bind-ddns']['status']". Then merge default and specific
(client or server) configurations and store the result in
"run_state['bind-ddns']['config']".

Note: init is included in all recipes.

package

Install Bind package.

package_client

Install Bind utils package.

config

Configure Bind server: named.conf, keys and zones.
Then check configuration through named-checkconf.

service

Enable and start named service, subscribes on named-checkconf resource.

nsupdate

Call bind-ddns default provider (which call nsupdate command) based on
attribute records. See [.kitchen.yml](.kitchen.yml) for more information.

Replace some missing configuration attributes:
- domain (name attribute) by the FQDN
- data by the ip defined in "node[:ipaddress]"
- zone by the tail part of the domain

resolvconf

Set resolv.conf using server attribute.

client

Install Bind utils, configure resolv.conf if requested (by attribute
set_resolv_conf) with recipe resolvconf and call nsupdate recipe.

server

Install, configure and launch Bind. Then call client recipe.

Resources/Providers

default

Add, update or remove a DNS record using nsupdate. Read the
[resources/default.rb](resource file) for more details.

Simple example:
ruby
bind_ddns 'test.foo' do
server 'ns.foo'
data "10.11.12.13"
keyname 'foo'
secret 'XXXX'
end

Use action :delete to delete an entry (default is :add).
