elasticsearchHow do I configure Elasticsearch with a YML file?

Configuration of Elasticsearch with a YML file can be done by editing the elasticsearch.yml file. This file is usually located in the config directory of the Elasticsearch installation. The file contains configuration settings for the Elasticsearch instance.

Example code

# Configure the cluster name
cluster.name: my-cluster

# Configure node name
node.name: node-1

The first line of code configures the cluster name for the Elasticsearch instance. The second line configures the node name for the instance.

The configuration settings in the elasticsearch.yml file can be changed to customize the Elasticsearch instance. For example, the following can be configured:

  • http.port: Configure the HTTP port used for communication.
  • node.data: Enable or disable the node from storing data.
  • network.host: Configure the network host to bind to.
