After installing the operator (please refer to the User Guide for details) you can deploy OpenSearch clusters using a separate helm chart.
helm install [RELEASE_NAME] opensearch-operator/opensearch-clusterhelm uninstall [RELEASE_NAME]Version 3.0.0 of opensearch-cluster helm chart is a fully refactored chart. Before upgrading to v3 check that default chart values matches with your configuration.
In v3 opensearchCluster variable was replaced by cluster. The configuration structure of each custom resource (OpenSearchCluster, OpensearchIndexTemplate, etc) follows the corresponding CRD documentation.
Make sure to test the upgrade process on none-production environment first.
If the cluster was installed by using the default values.yaml, then the upgrade could be done by running:
helm repo update
helm upgrade [RELEASE_NAME] opensearch-operator/opensearch-clusterBy default, the installation will deploy a node pool consisting of three master nodes with the dashboard enabled. For the entire configuration, check helm chart values.
To further customize your OpenSearchCluster installation, you can utilize configuration overrides and modify your values.yaml, this allows you to tailor various aspects of the installation to meet your specific requirements.
Version 3 of the helm chart is designed to have configuration options with the same format and naming as it is defined in the operator doc.
