Puppet module to manage the supervisord process control system.

Functions available to configure

• programs
• groups
• fcgi-programs
• eventlisteners

Examples

Configuring supervisord with defaults

Install supervisord with pip and install an init script if available

include supervisord

Install supervisord and pip

Install supervisord and install pip if not available.

class supervisord {
  $install_pip  => true,
}

This will download setuptool and install pip with easy_install.

You can pass a specific url with $setuptools_url = 'url'

Install without pip

If you want to use your system package manager you can specify that with supervisord::package_provider.

You'll also likely need to adjust the supervisord::service_name to match that installed by the system package. If you're using Debian or Redhat OS families you'll also want to disable the init scripts with supervisord::install_init = false.

Note: Only Debian and RedHat families have an init script currently.

Configure a program

supervisord::program { 'myprogram':
  command     => 'command --args',
  priority    => '100',
  environment => {
    'HOME'   => '/home/myuser',
    'PATH'   => '/bin:/sbin:/usr/bin:/usr/sbin',
    'SECRET' => 'mysecret'
  }
}

You may also specify a variable for a hiera lookup to retreive your environment hash. This allows you to reuse existing environment variable hashes.

supervisord::program { 'myprogram':
  command  => 'command --args',
  priority => '100',
  env_var  => 'my_common_envs'
}

Or you can fully define your programs in hiera:

supervisord::programs:
  'myprogram':
    command: 'command --args'
    autostart: yes
    autorestart: 'true'
    environment:
      HOME: '/home/myuser'
      PATH: '/bin:/sbin:/usr/bin:/usr/sbin'
      SECRET: 'mysecret'

Configure a group

supervisord::group { 'mygroup':
  priority => 100,
  programs  => ['program1', 'program2', 'program3']
}

Configure an eventlistener

supervisord::eventlistener { 'mylistener':
  command  => 'command --args',
  events   => ['PROCESS_STATE', 'PROCESS_STATE_START']
  priority => '100',
  env_var  => 'my_common_envs'
}

Configure an rpcinterface

supervisord::rpcinterface { 'laforge':
  rpcinterface_factory => 'mr.laforge.rpcinterface:make_laforge_rpcinterface'
}

Run supervisorctl Commands

Should you need to run a sequence of command with supervisorctl you can use the define type supervisord::supervisorctl

supervisord::supervisorctl { 'restart_myapp':
  command => 'restart',
  process => 'myapp'
}

You can also issue a command without specifying a process.

Development

If you have suggestions or improvements please file an issue or pull request, i'll try and sort them as quickly as possble.

If you submit a pull please try and include tests for the new functionality/fix. The module is tested with Travis-CI.
