Both are currently supported, but `opensearch.opster.io` is deprecated. Please see the Migration Guide for details.\n\n## Getting started\n\nThe Operator can be easily installed using Helm on any CNCF-certified Kubernetes cluster:\n\n1. Add the helm repo: `helm repo add opensearch-operator https://opensearch-project.github.io/opensearch-k8s-operator/`\n2. Install the Operator: `helm install opensearch-operator opensearch-operator/opensearch-operator`\n\nAfter installation, you can deploy your first OpenSearch cluster by creating an `OpenSearchCluster` custom resource. Please refer to the [User Guide](./docs/userguide/main.md) for detailed instructions and configuration options.\n\n## Video Tutorial\n\nLearn how to install and use the operator with the [OpenSearch Kubernetes Operator Tutorial Series on YouTube](https://pulse.support/kb/running-opensearch-on-kubernetes-video-tutorial-series).\n\n[![Watch the video](https://github.com/user-attachments/assets/3e8881b4-4b93-4322-86e2-f46baa01cad0)](https://pulse.support/kb/running-opensearch-on-kubernetes-video-tutorial-series)\n\n\n## Features\n\n- Deploy and manage OpenSearch clusters with multiple node pools\n- Deploy and configure OpenSearch Dashboards\n- Configure all node roles (cluster_manager, data, ingest, coordinating, etc.)\n- Scale cluster resources manually, per node pool\n- Rolling version upgrades with quorum-safe restarts\n- Online volume expansion for disk scaling\n- Certificate management with TLS hot reloading\n- Multi-namespace support for managing clusters across organizational boundaries\n- Plugin installation during bootstrap phase\n\n## Compatibility\n\nThe opensearch k8s operator aims to be compatible to all supported opensearch versions. Please check the table below for details:\n\n\n| Operator Version                                            | Min Supported Opensearch Version | Max Supported Opensearch Version | Comment                                    |\n| ----------------------------------------------------------- |----------------------------------| -------------------------------- | ------------------------------------------ |\n| 3.0.0                                                       | 2.19.2                           | latest 3.x                       | Supports the latest OpenSearch 3.x version. |\n| 2.8.0                                                       | 2.19.2                           | latest 3.x                       | Supports the latest OpenSearch 3.x version. |\n| 2.7.0\u003cbr\u003e2.6.1\u003cbr\u003e2.6.0\u003cbr\u003e2.5.1\u003cbr\u003e2.5.0                    | 1.3.x                            | 2.19.2                       | Supports the OpenSearch 2.19.2 version. |\n\n\nThis table only lists versions that have been explicitly tested with the operator, the operator will not prevent you from using other versions. Newer minor versions (2.x) not listed here generally also work but you should proceed with caution and test it out in a non-production environment first.\n\n## Development\n\nIf you want to develop the operator, please see the separate [developer docs](./docs/developing.md).\n\n## Contributions\n\nWe welcome contributions!
