Elasticsearch

What is Elasticsearch?

Elasticsearch is an open-source search and analytics engine designed for fast, scalable data retrieval—ideal for handling large volumes of both structured and unstructured data.

How to Deploy Elasticsearch on Coolify

There are two ways to deploy Elasticsearch on Coolify:

Elasticsearch as a standalone service (no GUI)
Elasticsearch with Kibana (GUI)

Elasticsearch as a Standalone Service

Create a new resource on Coolify and select Elasticsearch with Kibana from the service list.
Click the Deploy button to pull the Docker images and start the containers.
Once the Elasticsearch service shows as healthy, you can access it via its assigned domain.

⚠️ Note: This version does not include a GUI—you’ll need to interact with it via CLI tools or APIs.

Deploy Elasticsearch with Kibana

Create a new resource on Coolify and select Elasticsearch with Kibana from the service list.
Click the Deploy button to pull the Docker images and start the containers.
Once the Elasticsearch service is running and the Kibana Token Generator shows an exited status:
- Open the logs of the Kibana Token Generator service.
- Copy the Service Token from the logs.
- Paste the token into the ELASTICSEARCH_SERVICEACCOUNTTOKEN environment variable.
- Restart the service (click the Restart button).
After both Elasticsearch and Kibana services are running healthy, visit the domain assigned to the service.
- You’ll be presented with the Elastic login page.
- Username: elastic
  Password: value of the SERVICE_PASSWORD_ELASTICSEARCH environment variable.

Notes for Elasticsearch with Kibana

It can take over 2 minutes for all services to fully start (depending on your server’s performance).
The JVM heap size is set to 512MB by default to prevent Elasticsearch from exhausting server memory.

To increase this value, modify the environment variable:
ES_JAVA_OPTS=-Xms512m -Xmx512m in the Docker Compose file.
The Kibana Token Generator service is designed to run once and then exit. This is expected behavior and does not impact the health of the Elastic or Kibana services.
Clustering is disabled by default via the discovery.type=single-node environment variable.

Update this setting if clustering is required.
