## Overview
|
||
|
||
This module provides a standard library of resources for Puppet modules.
|
||
|
||
## Module Description
|
||
|
||
Puppet modules make heavy use of this standard library. The stdlib module adds the following resources to Puppet:
|
||
|
||
* Stages
|
||
* Facts
|
||
* Functions
|
||
* Defined types
|
||
* Data types
|
||
* Providers
|
||
|
||
> *Note:* As of version 3.7, Puppet Enterprise no longer includes the stdlib module. If you're running Puppet Enterprise, you should install the most recent release of stdlib for compatibility with Puppet modules.
|
||
|
||
## Setup
|
||
|
||
[Install](https://puppet.com/docs/puppet/latest/modules_installing.html) the stdlib module to add the functions, facts, and resources of this standard library to Puppet.
|
||
|
||
If you are authoring a module that depends on stdlib, be sure to [specify dependencies](https://puppet.com/docs/puppet/latest/modules_installing.html) in your metadata.json.
|
||
|
||
## Usage
|
||
|
||
Most of stdlib's features are automatically loaded by Puppet. To use standardized run stages in Puppet, declare this class in your manifest with `include stdlib`.
|
||
|
||
When declared, stdlib declares all other classes in the module. This currently consists of `stdlib::manage` and `stdlib::stages`.
|
||
|
||
The `stdlib::stages` class declares various run stages for deploying infrastructure, language runtimes, and application layers. The high level stages are (in order):
|
||
|
||
* setup
|
||
* main
|
||
* runtime
|
||
* setup_infra
|
||
* deploy_infra
|
||
* setup_app
|
||
* deploy_app
|
||
* deploy
|
||
|
||
Sample usage:
|
||
|
||
```puppet
|
||
node default {
|
||
include stdlib
|
||
class { java: stage => 'runtime' }
|
||
}
|
||
```
|
||
|
||
The `stdlib::manage` class provides an interface for generating trivial resource declarations via the `create_resources` parameter. Depending on your usage, you may want to set `hiera`'s `lookup_options` for the `stdlib::manage::create_resources:` element.
|
||
|
||
```yaml
|
||
---
|
||
stdlib::manage::create_resources:
|
||
file:
|
||
/etc/somefile:
|
||
ensure: file
|
||
owner: root
|
||
group: root
|
||
package:
|
||
badpackage:
|
||
ensure: absent
|
||
```
|
||
|
||
## Reference
|
||

#### `Stdlib::Ipv4`

|
||
|
||
#### `Stdlib::Ipv6`
|
||
|

|
||
|
||
#### `Stdlib::Ip_address`
|
||
|
||
This type is no longer available. To make use of this functionality, use [Stdlib::IP::Address](https://github.com/puppetlabs/puppetlabs-stdlib#stdlibipaddress)
|
||
|
||
#### `Stdlib::IP::Address`
|
||
|
||
Matches any IP address, including both IPv4 and IPv6 addresses. It will match them either with or without an address prefix as used in CIDR format IPv4 addresses.
|
||
|
||
Examples:
|
||
|
||
```
|
||
'127.0.0.1' =~ Stdlib::IP::Address # true
|
||
'10.1.240.4/24' =~ Stdlib::IP::Address # true
|
||
'52.10.10.141' =~ Stdlib::IP::Address # true

```
|
||
|
||
#### `Stdlib::IP::Address::V4`
|
||
|
||
Match any string consisting of an IPv4 address in the quad-dotted decimal format, with or without a CIDR prefix. It will not match any abbreviated form (for example, 192.168.1) because these are poorly documented and inconsistently supported.
|
||
|
||
Examples:
|
||
|
||
```
|
||
'127.0.0.1' =~ Stdlib::IP::Address::V4 # true

'12AB::CD30:192.168.0.1' =~ Stdlib::IP::Address::V4 # false
|
||
```
|
||
|
||
Valid values: An IPv4 address.

|
||
#### `Stdlib::IP::Address::V6`

|
||
```

||
'127.0.0.1' =~ Stdlib::IP::Address::V6 # false
|
||
'10.1.240.4/24' =~ Stdlib::IP::Address::V6 # false
|
||
'FEDC:BA98:7654:3210:FEDC:BA98:7654:3210' =~ Stdlib::IP::Address::V6 # true
|
||
'FF01:0:0:0:0:0:0:101' =~ Stdlib::IP::Address::V6 # true
|
||
'FF01::101' =~ Stdlib::IP::Address::V6 # true

but not '192.168.0.6').
|
||
|
||
Valid values: An IPv4 address with a CIDR provided eg: '192.186.8.101/105'. This will match anything inclusive of '192.186.8.101' to '192.168.8.105'.
|
||
|
||
#### `Stdlib::IP::Address::V4::Nosubnet`
|
||
|
||
Match an IPv4 address only if the address does not contain an address prefix (for example, it will match '192.168.0.6' but not '192.168.0.6/24').

||
Valid values: An IPv4 address with no subnet.

|
||
|
||
#### `Stdlib::IP::Address::V6::Compressed`
|
||
|
||
Match an IPv6 address which may contain `::` used to compress zeros as documented in section 2.2.2 of [RFC 2373](https://www.ietf.org/rfc/rfc2373.txt). It will match addresses with or without an address prefix as documented in section 2.3 of [RFC 2373](https://www.ietf.org/rfc/rfc2373.txt).

## Development
|
||
|
||
Puppet modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad hardware, software, and deployment configurations that Puppet is intended to serve. We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see our [module contribution guide](https://github.com/puppetlabs/puppetlabs-stdlib/blob/main/CONTRIBUTING.md).
