Install Grafana Alloy with Chef

You can use Chef to install and manage Alloy.

Before you begin

These steps assume you already have a working Chef setup.
You can add the following resources to any recipe.
These tasks install Alloy from the package repositories. The tasks target Linux systems from the following families:
- Debian, including Ubuntu
- RedHat Enterprise Linux, including Fedora
- Amazon Linux

Steps

To add Alloy to a host:

Add the following resources to your Chef recipe to add the Grafana package repositories to your system:

if platform_family?('debian', 'rhel', 'amazon', 'fedora')
  if platform_family?('debian')
    remote_file '/etc/apt/keyrings/grafana.gpg' do
      source 'https://apt.grafana.com/gpg.key'
      mode '0644'
      action :create
      end

    file '/etc/apt/sources.list.d/grafana.list' do
      content "deb [signed-by=/etc/apt/keyrings/grafana.gpg] https://apt.grafana.com/ stable main"
      mode '0644'
      notifies :update, 'apt_update[update apt cache]', :immediately
    end

    apt_update 'update apt cache' do
      action :nothing
    end
  elsif platform_family?('rhel', 'amazon', 'fedora')
    yum_repository 'grafana' do
      description 'grafana'
      baseurl 'https://rpm.grafana.com/oss/rpm'
      gpgcheck true
      gpgkey 'https://rpm.grafana.com/gpg.key'
      enabled true
      action :create
      notifies :run, 'execute[add-rhel-key]', :immediately
    end

    execute 'add-rhel-key' do
      command "rpm --import https://rpm.grafana.com/gpg.key"
      action :nothing
    end
  end
else
    fail "The #{node['platform_family']} platform is not supported."
end

Add the following resources to install and enable the alloy service:

package 'alloy' do
  action :install
  flush_cache [ :before ] if platform_family?('amazon', 'rhel', 'fedora')
  notifies :restart, 'service[alloy]', :delayed
end

service 'alloy' do
  service_name 'alloy'
  action [:enable, :start]
end

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 configuration file for the service to use.
