Default value: true

keyfile

bind::zone::primary

The parameters source or content can be used to have Puppet manage the content of the zone file. No content is managed if both parameters are left undefined. For a dynamic updatable zone the parameters source and content are only applied if the zone file does not yet exist. This can be used to deploy a zone file template on the first Puppet run and have Bind manage the content subsequently.

Examples

Create a primary zone
bind::zone::primary { 'example.com':
  source => 'puppet:///modules/profile/example.com.zone',
}
Use DNSSEC signing for a primary zone using a DNSSEC policy
bind::zone::primary { 'example.com':
  dnssec_enable  => true,
  dnssec_policy  => 'standard',
  inline_signing => true,
  source         => 'puppet:///modules/profile/example.com.zone',
}
Create a dynamic updatable zone with an initial zone file
bind::zone::primary { '_acme-challenge.example.com':
  update_policy => ['grant certbot name _acme-challenge.example.com. txt'],
  source        => 'puppet:///modules/profile/acme-template.zone',
}

Parameters

The following parameters are available in the bind::zone::primary defined type:

also_notify

Data type: Array[String]

Secondary servers that should be notified in addition to the nameservers that are listed in the zone file.

Default value: []

update_policy

Enable dynamic updates for the zone and define the update policy. This can either be the string local or an array of strings. Using the string local enables an automatically created session key local-ddns stored on the server. Otherwise the array should contain individual grant or deny rules.

The zone file content can not be managed by Puppet for a dynamic zone. If the parameters source or content are set, the zone file will only be created by Puppet initially if it does not exist. An existing zone file will not be overwritten by Puppet.

Resource types

dnssec_key

Notice: Automatic key rollover using this type is not thoroughly tested. Use bind::dnssec_policy to define a DNSSEC policy (available with Bind 9.16) and let Bind handle the heavy lifting instead of Puppet.

All intervals are interpreted as seconds if no unit is given. The following interval units can be used: y (year), mo (months), w (weeks), d (days), h (hours), mi (minutes).

Examples for valid intervals: 1y, 12mo, 1w, 7d, 24h, 720mi

The following diagram illustrates the lifecycle of the keys:

key-1 ---- active ----------><-- retired --><-- deleted --

key-2     <--- published ---><---------- active ----------><-- retired

          <----------------->
            prepublication
               interval

Key-2 is published with a prepublication interval while key-1 is still active. The activation time of key-2 matches the deactivation time of key-1. Key-1 changes state to retired when it is deactivated and is deleted eventually. The cycle continues with additional keys.

Examples

Create a Key Signing Key using defaults
dnssec_key { 'example.com':
  key_directory => '/etc/bind/keys',
  ksk           => true,
}
Create a Zone Signing Key using a specified algorithm and key size
dnssec_key { 'ZSK/example.com':
  zone          => 'example.com',
  key_directory => '/etc/bind/keys',
  algorithm     => 'RSASHA256',
  bits          => 2048,
}
Create Zone Signing Keys using automatic key rollover
dnssec_key { 'ZSK/example.com':
  zone          => 'example.com',
  key_directory => '/etc/bind/keys',
  publish       => '2w',
  active        => '1y',
  retire        => '4w',
  delete        => '1w',
  successor     => true,
}

Properties

The following properties are available in the dnssec_key type.

ensure

Valid values: present, absent

Specifies whether the destination file should exist. Setting this to "absent" tells Puppet to delete the destination file if it exists, and negates the effect of any other parameters.

Default value: present

Parameters

The following parameters are available in the dnssec_key type.

active

Valid values: %r{^[0-9]+(y|mo|w|d|h|mi)?$}

The time interval that the key will be used for signing the zone.

The cryptographic algorithm that the key should use.

Default value: RSASHA1

bits

Valid values: %r{^[0-9]+$}

The number of bits in the key. The possible range depends on the selected algorithm:

RSA : 512 .. 2048 DH : 128 .. 4096 DSA : 512 .. 1024 and an exact multiple of 64 HMAC : 1 .. 512

Elliptic curve algorithms don't need this parameter.

key_directory

ksk

Valid values: true, false

Whether the key should be a Key Signing Key.

Default value: false

name

namevar

The name of the resource.

Whether the key should be NSEC3-capable.

Default value: false

precreate

Valid values: %r{^[0-9]+(y|mo|w|d|h|mi)?$}

The time interval before prepublication in which the key will be created. The interval must be long enough to ensure Puppet will run during this interval.

prepublish

Valid values: %r{^[0-9]+(y|mo|w|d|h|mi)?$}

The time interval before activation when the key will be published.

provider

The specific backend to use for this dnssec_key resource. You will seldom need to specify this --- Puppet will usually discover the appropriate provider for your platform.

purge

Valid values: true, false

Whether old keys should be purged after they are retired.

Default value: false

retire

Valid values: %r{^[0-9]+(y|mo|w|d|h|mi)?$}

The time interval that the key is still published after it became inactive.

revoke

Valid values: %r{^[0-9]+(y|mo|w|d|h|mi)?$}

The time interval that the key will have the revoke bit set. This parameter may only be used for zone-signing keys.

rrtype

Valid values: DNSKEY, KEY

The resource record type to use for the key.

Default value: DNSKEY

successor

Valid values: true, false

Whether the key should be created as an explicit successor to an existing key. In this case the name, algorithm, size and type of the key will be take from the existing key. The activation date will match the inactivation date of the existing key.

Default value: false

zone

Valid values: %r{^[a-zA-Z][a-zA-Z0-9.-]+\.[a-zA-Z]+$}

The zone for which the key should be generated. This must be a valid domain name. Defaults to the resource title if unset.

Functions

bind::gencfg

Type: Puppet Language

Generate a Bind configuration snippet from a hash. Each key of the hash is used as a config option. The can be a string, a numeric value, a boolean or an array or hash. the config option is terminated with a ';' char.

Strings and numeric values are included normally as parameter value. A boolean value is written as 'yes' or 'no'. Arrays are enclosed in braces and array values are returned as a single line if the number of elements is zero or one. Otherwise a new line is used for each value. Hashes are also enclosed in braces and the keys and values are processed recursively.

Examples

String value
bind::gencfg({ 'foo' => 'bar' }, 2)

  foo bar;
Numeric value
bind::gencfg({ 'foo' => 42 }, 2)

  foo 42;
Boolean value
bind::gencfg({ 'foo' => true }, 2)

  foo yes;
Array value with zero elements
bind::gencfg({ 'foo' => [] }, 2)

  foo { };
Array value with one element
bind::gencfg({ 'foo' => ['bar'] }, 2)
