Using official Elasticsearch container elasticsearch.
Copy docker-compose.elasticsearch.yaml to your project's .ddev folder.
From within the container, the elasticsearch container is reached at hostname: ddev--elasticsearch, port: 9200, so the server URL might be http://ddev-<projectname>-elasticsearch:9200. You can also use the non-SSL, and SSL urls to access it: http://<projectname>.ddev.site:9200, and https://<projectname>.ddev.site:9201
You can access the Elasticsearch server directly from the host for debugging purposes by visiting http://<projectname>.ddev.site:9200. If you have SSL enabled, which is recommended, you can access Elasticsearch via https://<projectname>.ddev.site:9201
This configuration limits memory usage to 512mb. This should be enough for most projects, but if your elasticsearch service stops with no obvious reason, increase your docker max memory or/and the service max memory.
You can use ddev logs -s elasticsearch to investigate what the elasticsearch daemon has been up to, or if you have a RAM-related crash.
