Puppet module for mesosphere's Marathon

This module installs and configures Mesosphere's marathon task runner.

Classes:

• marathon: This is the main class, all the other sub-classes inherit from it.
  • Parameters:

        class marathon(
        # Install or uninstall (present|absent)
          $installation_ensure      = 'present',
        # Marathon binary url
          $url                      = 'https://downloads.mesosphere.io/marathon/v0.8.2-RC1/marathon-0.8.2-RC1.tgz',
        # Marathon binary digest string
          $digest_string            = '45a481f4703e1455f8aafa037705c9033200f2dc7f9d5e6414acde533d6cb935',

          $install_dir              = '/opt/marathon',
        # The username that marathon will submit tasks as
          $user                     = 'root',
        # Whether or not to create scripts in /usr/local/bin
          $create_symlinks          = true,
        # Create symlinks for the marathon binaries for easier access
          $haproxy_discovery        = false,
        # Create and manage the marathon service
          $manage_service           = true,
        # The marathon service's name
          $service_name             = 'marathon',
        # The marathon options
          $options                  = hiera('classes::marathon::options', {}),
        # Manage the firewall rules
          $manage_firewall          = false,
        # Manage the user that the tasks will be submitted as
          $manage_user              = true,
        # Whether or not the integrity of the archive should be verified
          $checksum                 = true,
        # Global haproxy options
          $haproxy_global_options   = hiera('classes::haproxy::global_options', {}),
        # Default HAproxy options
          $haproxy_default_options  = hiera('classes::haproxy::default_options', {})
        ) {
    

• marathon::install: This is the class that actually installs and configures marathon
  • Parameters:

        class marathon::install (
        # Install or uninstall (present|absent)
          $installation_ensure     = 'present',
        # Marathon binary url
          $url                     = $marathon::url,
        # Marathon binary digest string
          $digest_string           = $marathon::digest_string,
        # The digest type
          $digest_type             = 'sha256',
        # Temporary directory to download the files to
          $tmp_dir                 = $marathon::tmp_dir,
        # Marathon Installation directory
          $install_dir             = $marathon::install_dir,
        # The username that marathon will submit tasks as
          $user                    = $marathon::user,
        # Whether or not to create scripts in /usr/local/bin
          $create_symlinks         = $marathon::create_symlinks,
        # Create symlinks for the marathon binaries for easier access
          $haproxy_discovery       = $marathon::haproxy_discovery,
        # Create and manage the marathon service
          $manage_service          = $marathon::manage_service,
        # The marathon service's name
          $service_name            = $marathon::service_name,
        # The marathon options
          $options                 = $marathon::options,
        # Manage the firewall rules
          $manage_firewall         = $marathon::manage_firewall,
        # Manage the user that the tasks will be submitted as
          $manage_user             = $marathon::manage_user,
        # Whether or not the integrity of the archive should be verified
          $checksum                = $marathon::checksum,
        # Global haproxy options
          $haproxy_global_options  = $marathon::haproxy_global_options,
        # Default HAproxy options
          $haproxy_default_options = $marathon::haproxy_default_options
        ) inherits marathon {
    

Usage example:

```puppet
class {'marathon':
    manage_firewall => true,
    service_name    => 'marathon',
    manage_user     => true,
    user            => 'root'
}
```

Important:

Please see [The Marathon documentation](https://mesosphere.github.io/marathon/docs/command-line-flags.html) before you use to use this module.

Other notes

Pay attention when specifying the marathon options in Hiera, specially the ones requiring double quotes or special characters, such as in the example below.

    "ACCESS_CONTROL_ALLOW_ORIGIN":"\\\"*\\\"",

As you can see, since I am using the json Hiera backend, both the " and the \ need to be present within the service file. Due to the fact that within the template they are already within double quotes, I had to make sure I escape them propperly.

Have fun!
