This guide covers configuring continuous integration pipelines for projects that have a Elasticsearch dependency. If you’re new to Drone please read our Tutorial and build configuration guides first.

Basic Example

In the below example we demonstrate a pipeline that launches a Elasticsearch service container. The elastic server will be available at database:9200, where the hostname matches the service container name.

Common Problems

Initialization

If you are unable to connect to the Elastic container please make sure you are giving the instance adequate time to initialize and begin accepting connections.

Incorrect Hostname

You cannot use 127.0.0.1 or localhost to connect with the database. If you are unable to connect to the database please verify you are using the correct hostname, corresponding with the name of the container.

Bad:
