如何获取AWS OpenSearch Serverless集合的OpenSearch版本？

在常规OpenSearch托管集群中，你可以发送GET /_cluster/stats请求，从响应的nodes.versions字段获取节点运行的OpenSearch版本，示例响应如下：

{
  "_nodes": {
      "total": 1,
      "successful": 1,
      "failed": 0
  },
  "cluster_name": "opensearch",
  // ...
  "nodes": {
    "count": {
      "total": 1,
      "cluster_manager": 1,
      "coordinating_only": 0,
      "data": 1,
      "ingest": 1,
      "master": 1,
      "remote_cluster_client": 1
    },
    "versions": [
      "2.3.0"
    ],
  },
  // ...
}

但向OpenSearch Serverless集合发送该请求会返回404，且使用AWS CLI命令aws opensearchserverless batch-get-collection --name <collection-name>查询集合信息时，响应也不包含版本信息：

{
    "collectionDetails": [
        {
            "arn": REDACTED,
            "collectionEndpoint": REDACTED,
            "createdDate": REDACTED,
            "dashboardEndpoint": REDACTED,
            "description": REDACTED,
            "id": REDACTED,
            "kmsKeyArn": REDACTED,
            "lastModifiedDate": REDACTED,
            "name": REDACTED,
            "status": "ACTIVE",
            "type": "SEARCH"
        }
    ],
    "collectionErrorDetails": []
}

可行的获取方法 #

• 发送GET请求到集合根端点
  直接向OpenSearch Serverless集合的端点发送GET /请求，响应中会包含version字段，示例响应如下：

  {
    "name": "xxxx",
    "cluster_name": "xxxx",
    "cluster_uuid": "xxxx",
    "version": {
      "number": "2.7.0",
      "build_type": "tar",
      "build_hash": "xxxx",
      "build_date": "xxxx",
      "build_snapshot": false,
      "lucene_version": "9.6.0",
      "minimum_wire_compatibility_version": "7.10.0",
      "minimum_index_compatibility_version": "7.0.0"
    },
    "tagline": "The OpenSearch Project: https://opensearch.org/"
  }
  

• 通过OpenSearch Dashboard查看
  访问集合对应的Dashboard端点，在页面左下角点击集群名称，或进入关于页面，即可查看当前运行的OpenSearch版本。

• 参考AWS官方版本支持说明
  AWS会维护OpenSearch Serverless支持的版本列表，可通过官方文档确认当前服务支持的版本范围，结合集合创建时间推断大致版本（前两种方法可获取精确版本）
