## Description

This cookbook enables the configuration of generic [Chef resources](https://docs.chef.io/resources.html) by attributes.

The following resource list includes all Chef resources mapped by default: 

```
apt_repository
apt_update
apt_package
yum_repository
yum_package
package
group
user
directory
file
remote_file
link
template
git
subversion
execute
bash
script
service
systemd_unit
route
mount
```

### Configuration

Append other resources to the resource list mapped by this cookbook with the attribute `base/resources`.

Following Chef role illustrates this for the `cron` resource:

```ruby
name 'cron'
description 'Cron configuration'
run_list( 'recipe[base]' )
default_attributes(

  base: { resources: [ 'cron' ] },

  cron: {
    'noop': {
      hour: '5',
      minute: '0',
      command: '/bin/true'
    }
  }

)
```

### Usage

Take a look to the [test/roles/](test/roles) directory for a list of example roles using this cookbook.

Following Chef role configures `ntpd` on Debian and CentOS:

```ruby
name 'ntpd'
description 'ntpd configuration'
run_list( 'recipe[base]' )
default_attributes(
 
  ##
  # PACKAGES
  # 
  package: [ 'ntp','ntpdate' ],

  # Remove the default NTP service on CentOS
  yum_package: { chrony: { action: :remove } },
