Reloading Elastic output template

The output installs the template only on start?
What if I want to change my template ? Do I have to restart logstash? or do I have to install it manually.

The template is handwritten

Seems that it does it when the plugin is registered

logstash-plugins/logstash-output-elasticsearch/blob/71b2e530873728e60355e02adb3a9e7fa8c660e1/lib/logstash/outputs/elasticsearch/common.rb#L26


VERSION_TYPES_PERMITTING_CONFLICT = ["external", "external_gt", "external_gte"]


def register
  @stopping = Concurrent::AtomicBoolean.new(false)
  # To support BWC, we check if DLQ exists in core (< 5.4). If it doesn't, we use nil to resort to previous behavior.
  @dlq_writer = dlq_enabled? ? execution_context.dlq_writer : nil


  setup_hosts # properly sets @hosts
  build_client


  install_template
  check_action_validity
  @bulk_request_metrics = metric.namespace(:bulk_requests)
  @document_level_metrics = metric.namespace(:documents)


  @logger.info("New Elasticsearch output", :class => self.class.name, :hosts => @hosts.map(&:sanitized).map(&:to_s))
end


# Receive an array of events and immediately attempt to index them (no buffering)
