​Elasticsearch configuration

Elasticsearch is an Enterprise Edition functionality.

The most important thing is to configure the way Kestra connects to the Elasticsearch cluster.

Here is a minimal configuration example:

kestra:
  elasticsearch:
    client:
      http-hosts: "http://localhost:9200"
  repository:
    type: elasticsearch

Here is another example with a secured Elasticsearch cluster with basic authentication:

kestra:
  elasticsearch:
    client:
      http-hosts:
        - "http://node-1:9200"
        - "http://node-2:9200"
        - "http://node-3:9200"
      basic-auth:
        username: "<your-user>"
        password: "<your-password>"
  repository:
    type: elasticsearch

kestra.elasticsearch.client.trust-all-ssl

Default false, if you enable this option, we trust all certificate during connection. Useful for development server with self-signed certificate.

kestra:
  elasticsearch:
    client:
      http-hosts: "https://localhost:9200"
      trust-all-ssl: true

kestra.elasticsearch.defaults.indice-prefix

This configuration allows to change the indices prefix. By default, the prefix will be kestra_.

For example, if you want to share a common Elasticsearch cluster for multiple instances of Kestra, add a different prefix for each instance like this:

kestra:
  elasticsearch:
    defaults:
      indice-prefix: "uat_kestra"

kestra.elasticsearch.defaults.indices

This configuration allows to change indices settings created by kestra, example:

kestra:
  elasticsearch:
    defaults:
      indices:
        index.number_of_replicas: 0
