Install Grafana Alloy with Puppet

You can use Puppet to install and manage Alloy.

Before you begin

These steps assume you already have a working Puppet setup.
You can add the following manifest to any new or existing module.
The manifest installs Alloy from the package repositories. It targets Linux systems from the following families:
- Debian (including Ubuntu)
- RedHat Enterprise Linux (including Fedora)

Steps

To add Alloy to a host:

Make sure that the following module dependencies are declared and installed:

{
"name": "puppetlabs/apt",
"version_requirement": ">= 4.1.0 <= 7.0.0"
},
{
"name": "puppetlabs/yumrepo_core",
"version_requirement": "<= 2.0.0"
}

Create a new Puppet manifest with the following class to add the Grafana package repositories, install the alloy package, and run the service:

class grafana_alloy::grafana_alloy () {
  case $::os['family'] {
    'debian': {
      apt::source { 'grafana':
        location => 'https://apt.grafana.com/',
        release  => '',
        repos    => 'stable main',
        key      => {
          id     => 'B53AE77BADB630A683046005963FA27710458545',
          source => 'https://apt.grafana.com/gpg.key',
        },
      } -> package { 'alloy':
        require => Exec['apt_update'],
      } -> service { 'alloy':
        ensure    => running,
        name      => 'alloy',
        enable    => true,
        subscribe => Package['alloy'],
      }
    }
    'redhat': {
      yumrepo { 'grafana':
        ensure   => 'present',
        name     => 'grafana',
        descr    => 'grafana',
        baseurl  => 'https://packages.grafana.com/oss/rpm',
        gpgkey   => 'https://packages.grafana.com/gpg.key',
        enabled  => '1',
        gpgcheck => '1',
        target   => '/etc/yum.repo.d/grafana.repo',
      } -> package { 'alloy':
      } -> service { 'alloy':
        ensure    => running,
        name      => 'alloy',
        enable    => true,
        subscribe => Package['alloy'],
      }
    }
    default: {
      fail("Unsupported OS family: (${$::os['family']})")
    }
  }
}

To use this class in a module, add the following line to the module’s init.pp file:
ruby
```
include grafana_alloy::grafana_alloy
```

Configuration

The alloy package installs a default configuration file that doesn’t send telemetry anywhere.

The default configuration file location is /etc/alloy/config.alloy. You can replace this file with your own configuration, or create a new configuration file for the service to use.
