Puppet module to define elastic_template resource type. Doesn't ensure that the index is correct, but does ensure it's present.

elastic_template.pp

define elastic_template($host='localhost', $port='9200', $prefix='', $require=undef) {
  $es_templ = "${name}-template.json"
  file { "/tmp/${es_templ}":
    ensure  => present,
    source  => "puppet:///modules/${module_name}/${prefix}${es_templ}",
    require => $require,
  }

  $es_locn = "http://${host}:${port}/_template/${name}"
  exec { "curl -s -XPUT ${es_locn} -d @/tmp/${es_templ}":
    path    => '/usr/local/bin:/usr/bin:/bin',
    unless  => "test $(curl -s '${es_locn}?pretty=true' | wc -l) -gt 1",
    require => File["/tmp/${es_templ}"],
  }
}
