USAGE - Basic management¶ ↑

• Install haproxy with default settings

  class { "haproxy": }

• Disable haproxy service.

  class { "haproxy":
    disable => true
  }

• Disable haproxy service at boot time, but don’t stop if is running.

  class { "haproxy":
    disableboot => true
  }

  class { "haproxy":
    absent => true
  }

• Enable auditing without without making changes on existing haproxy configuration files

  class { "haproxy":
    audit_only => true
  }

USAGE - Overrides and Customizations¶ ↑

• Use custom sources for main config file

  class { "haproxy":
    source => [ "puppet:///modules/lab42/haproxy/haproxy.conf-${hostname}" , "puppet:///modules/lab42/haproxy/haproxy.conf" ], 
  }

• Use custom source directory for the whole configuration dir

  class { "haproxy":
    source_dir       => "puppet:///modules/lab42/haproxy/conf/",
    source_dir_purge => false, # Set to true to purge any existing file not present in $source_dir
  }

• Use custom template for main config file

  class { "haproxy":
    template => "example42/haproxy/haproxy.conf.erb",      
  }

• Define custom options that can be used in a custom template without the need to add parameters to the haproxy class

  class { "haproxy":
    template => "example42/haproxy/haproxy.conf.erb",    
    options  => {
      'LogLevel' => 'INFO',
      'UsePAM'   => 'yes',
