For detailed info about the logic and usage patterns of Example42 modules read README.usage on Example42 main modules set.

USAGE - Basic management

  • Install tomcat with default settings

    class { "tomcat": }
    
  • Disable tomcat service and create single tomcat instances (note for each for them you must specify (different) http_port and control_port

    class { "tomcat":
      disable => true
    }
    
    tomcat::instance { 'my_app':
      http_port    => '8088',
      control_port => '6088',
    }
    
    tomcat::instance { 'other_app':
      http_port    => '8089',
      control_port => '6089',
      ajp_port     => '9089',
    }
    
  • Disable tomcat service at boot time, but don't stop if is running.

    class { "tomcat":
      disableboot => true
    }
    
  • Remove tomcat package

    class { "tomcat":
      absent => true
    }
    
  • Enable auditing without making changes on existing tomcat configuration files

    class { "tomcat":
      audit_only => true
    }
    
  • Install a custom version of tomcat. The default is chose according to OS versions, but you can try to install a different one (given that a tomcat${version} packge is available)

    class { "tomcat": }
    
    On hiera set this key with the version value you want:
    tomcat::params::version: 7
    

Note: that some templates used by tomcat::instance may not be present for your version. You should provide them with the *_template parameters.

USAGE - Overrides and Customizations

  • Use custom sources for main config file

    class { "tomcat":
      source => [ "puppet:///modules/lab42/tomcat/tomcat.conf-${hostname}" , "puppet:///modules/lab42/tomcat/tomcat.conf" ], 
    }
    
  • Use custom source directory for the whole configuration dir

    class { "tomcat":
      source_dir       => "puppet:///modules/lab42/tomcat/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 { "tomcat":
      template => "example42/tomcat/tomcat.conf.erb",      
    }
    
  • Define custom options that can be used in a custom template without the need to add parameters to the tomcat class

      class { "tomcat":
        template => "example42/tomcat/tomcat.conf.erb",    
        options  => {
          'LogLevel' => 'INFO',
          'UsePAM'   => 'yes',
        },
      }
    
  • Automaticallly include a custom subclass

    class { "tomcat:"
      my_class => 'tomcat::example42',
    }
    

USAGE - Example42 extensions management

  • Activate puppi (recommended, but disabled by default) Note that this option requires the usage of Example42 puppi module

      class { "tomcat": 
        puppi    => true,
      }
    
  • Activate puppi and use a custom puppi_helper template (to be provided separately with a puppi::helper define ) to customize the output of puppi commands

      class { "tomcat":
        puppi        => true,
        puppi_helper => "myhelper", 
      }
    
  • Activate automatic monitoring (recommended, but disabled by default) This option requires the usage of Example42 monitor and relevant monitor tools modules

      class { "tomcat":
        monitor      => true,
        monitor_tool => [ "nagios" , "monit" , "munin" ],
      }
    
  • Activate automatic firewalling This option requires the usage of Example42 firewall and relevant firewall tools modules

      class { "tomcat":       
        firewall      => true,
        firewall_tool => "iptables",
        firewall_src  => "10.42.0.0/24",
        firewall_dst  => "$ipaddress_eth0",
      }
