Puppet open source

This use case describes how to use Puppet to configure systems — each system is connected to a server.

1. Install the Puppet master on an external server and configure it to manage systems running the software by following the instructions at www.puppetlabs.com.

2. Install and configure the Puppet agent on both systems by following the instructions at www.puppetlabs.com.

3. Verify if the Puppet master can communicate with the Puppet agents through the management network.

Sample configuration — manifest managing two systems

node 'R1.dell.com' {
   $int_enabled = true
   $int_loopback = '2.2.2.2'
   $int_layer3 = {
      e101-019-0  => {'int'=>'e101-019-0', 'address' => '19.0.0.1', 'netmask' => '255.255.255.0', 'cidr_netmask' => 24},
      e101-020-0  => {'int'=>'e101-020-0', 'address' => '20.0.0.1', 'netmask' => '255.255.255.0', 'cidr_netmask' => 24},
   }

   $bgp = {
       myasn => 65000,
       peergroupv4 => [ { name => 'R2', asn => 65000, peers => [ '19.0.0.2','20.0.0.2' ] } ]
   }
   include ibgp::switch
}

node 'R2.dell.com' {
   $int_enabled = true
   $int_loopback = '3.3.3.3'
   $int_layer3 = {
       e101-019-0  => { 'int'=> 'e101-019-0', 'address' => '19.0.0.2', 'netmask' => '255.255.255.0', 'cidr_netmask' => 24 },
       e101-020-0​  => { 'int'=> ' e101-020-0','address' => '21.0.0.1', 'netmask' => '255.255.255.0', 'cidr_netmask' => 24 },
   }

   $bgp = {
       myasn => 65000,
       peergroupv4 => [ { name => 'R1', asn => 65000, peers => [ '19.0.0.1','20.0.0.1' ] } ]
   }
   include ibgp::switch
}

Sample configuration — class definitions

class ibgp::switch {
   include ibgp::quagga
}

class ibgp::quagga {
   service { 'quagga':
       ensure    => running,
       hasstatus => false,
       enable    => true,
   }

   file { '/etc/quagga/daemons':
       owner  => quagga,
       group  => quagga,
       source => 'puppet:///modules/ibgp/quagga_daemons',
       notify => Service['quagga']
   }

   file { '/etc/quagga/Quagga.conf':
       owner   => root,
       group   => quaggavty,
       mode    => '0644',
       content => template('ibgp/Quagga.conf.erb'),
       notify  => Service['quagga']
   }
}
