#puppet-consul Build Status

##Installation

###What This Module Affects

  • Installs the consul daemon (via url or package)
  • Optionally installs a user to run it under
  • Installs a configuration file (/etc/consul/config.json)
  • Manages the consul service via upstart, sysv, or systemd
  • Optionally installs the Web UI

##Usage

class { 'consul':
  config_hash => {
      'datacenter' => 'east-aws',
      'data_dir'   => '/opt/consul',
      'log_level'  => 'INFO',
      'node_name'  => 'foobar',
      'server'     => true
  }
}

##Web UI

To install and run the Web UI, include ui_dir in the config_hash. You may also want to change the client_addr to 0.0.0.0 from the default 127.0.0.1, for example:

class { 'consul':
  config_hash => {
      'datacenter'  => 'east-aws',
      'data_dir'    => '/opt/consul',
      'ui_dir'      => '/opt/consul/ui',
      'client_addr' => '0.0.0.0',
      'log_level'   => 'INFO',
      'node_name'   => 'foobar',
      'server'      => true
  }
}

For more security options, consider leaving the client_addr set to 127.0.0.1 and use with a reverse proxy:

  $aliases = ['consul', 'consul.example.com']

  # Reverse proxy for Web interface
  include 'nginx'

  $server_names = [$::fqdn, $aliases]

  nginx::resource::vhost { $::fqdn:
    proxy       => 'http://localhost:8500',
    server_name => $server_names,
  }

Service Definition

To declare the availability of a service, you can use the service define. This will register the service through the local consul client agent and optionally configure a health check to monitor its availability.

consul::service { 'redis':
  tags           => ['master'],
  port           => 8000,
  check_script   => '/usr/local/bin/check_redis.py',
  check_interval => '10s',
}

##Limitations

Depends on the JSON gem, or a modern ruby.
