What is Puppet?

• One of the market leaders in configuration management
• Configuration management system that allows you to define the state of your IT infrastructure, then automatically enforces the correct state
• Works as well on a single server, as on thousands of physical and virtual machines
• Automates tasks that sysadmins often do manually
• Ensures consistency, reliability and stability

Puppet Basics

• puppet-agent, puppetserver, puppetdb
• Resources
• Classes
• Modules

Puppet Resources

Definition:

                        <TYPE> { '<TITLE>':
                          <ATTRIBUTE> => <VALUE>,
                        }    
                        

Puppet Resources

Special Attributes:

• ensure: present/absent (may take additional values depending on the resource)
• before: Applies a resource before the target resource
• require: Applies a resource after the target resource
• notify: Applies a resource before the target resource. The target resource refreshes if the notifying resource changes
• subscribe: Applies a resource after the target resource. The subscribing resource refreshes if the target resource changes

Puppet Resources

Example Part 1:

    file { 'vagrant-vhost.conf':
      path    => "/etc/apache2/sites-available/vagrant-vhost.conf",
      ensure  => file,
      source  => "puppet:///modules/apache/vagrant-vhost.conf",
      require => Package['apache2'],
      notify  => Service['apache2'],
      owner   => 'root',
      mode    => '0644',
    }
                        

Puppet Resources

Example Part 2:

    package { 'apache2':
      ensure => installed,
      before => File['vagrant-vhost.conf'],
    }
    service {'apache2':
      ensure    => running,
      subscribe => File['vagrant-vhost.conf'],
    }    
    

Puppet Classes

   class apache2 (String $version = 'latest') {
        file { 'vagrant-vhost.conf':
          path    => "/etc/apache2/sites-available/vagrant-vhost.conf",
          ensure  => file,
          source  => "puppet:///modules/apache/vagrant-vhost.conf",
          require => Package['apache2'],
          notify  => Service['apache2'],
          owner   => 'root',
          mode    => '0644',
        }
        package { 'apache2':
          ensure => $version,
          before => File['vagrant-vhost.conf'],
        }
        service {'apache2':
          ensure    => running,
          subscribe => File['vagrant-vhost.conf'],
        } 
    }
