Installation
Uses elasticsearch official image
ddev get ddev/ddev-elasticsearch
Using Elasticsearch 8
Post ddev get, run cp .ddev/elasticsearch/docker-compose.elasticsearch8.yaml .ddev/ to enable Elasticsearch 8.
Connection
To access the Elasticsearch container from within the web container, use the hostname elasticsearch and port 9200. For example, the server URL might be http://elasticsearch:9200. Alternatively, you can use the ddev.site URLs to access it via HTTP or HTTPS: http://<projectname>.ddev.site:9200 and https://<projectname>.ddev.site:9201. These URLs are also available from the host.
Configuration
Avoid modifying the provided docker-compose.elasticsearch.yaml file. Instead, create a docker-compose.elasticsearch_extras.yaml file for any customizations. For more information on defining additional services with Docker Compose, please refer to the official DDEV documentation.
Memory Limit
By default, this configuration limits the memory usage of the elasticsearch service to 512MB. This should be sufficient for most projects. However, if the service stops unexpectedly, you may need to increase the maximum memory allocation for Docker and/or the elasticsearch service. To do so, modify the ES_JAVA_OPTS environment variable in the docker-compose.elasticsearch_extras.yaml file.
Example for 2GB:
services:
elasticsearch:
environment:
- "ES_JAVA_OPTS=-Xms2g -Xmx2g"You can use ddev logs -s elasticsearch to investigate the Elasticsearch daemon's activity or to troubleshoot RAM-related crashes.
