Quickstart

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

Add the following specification to create a minimal Logstash deployment that will listen to a Beats agent or Elastic Agent configured to send to Logstash on port 5044, create the service and write the output to an Elasticsearch cluster named quickstart, created in the Elasticsearch quickstart.
