如何创建策略并将其添加到索引中？

Question

例如，X Time x之后删除索引的策略

我知道如何在Elasticsearch中做到这一点，例如，我可以创建一个策略

PUT _ilm/policy/logs_policy
    {
       "policy": {
        "phases": {
          "delete": {
            "min_age": "2m",
            "actions": {
              "delete": {}
            }
          }
        }
      }
    }

nex我可以将策略链接到索引

PUT logs/_settings
    {
      "index": {
        "lifecycle": {
          "name": "logs_policy"
        }
      }
    }

我想知道如何使用c＃.net

您可以使用

Answer 1

发送http请求

var settings = new ElasticsearchClientSettings(new Uri("http://localhost:9200"))
    .Authentication(new BasicAuthentication("elastic", "your_password")); // Replace with your credentials
var client = new ElasticsearchClient(settings);

// Step 1: Create ILM Policy using Raw API
var policyRequest = new
{
    policy = new
    {
        phases = new
        {
            delete = new
            {
                min_age = "2m",
                actions = new
                {
                    delete = new { }
                }
            }
        }
    }
};

var policyResponse = await client.Transport.RequestAsync<StringResponse>(
    new EndpointPath(Elastic.Transport.HttpMethod.PUT, "_ilm/policy/logs_policy"),  
    PostData.Serializable(policyRequest)
);

if (!policyResponse.ApiCallDetails.HasSuccessfulStatusCode)
{
    Console.WriteLine($"Error creating policy: {policyResponse.Body}");
    return;
}
Console.WriteLine("Policy created successfully.");

// Step 2: Apply ILM Policy to an Index using Raw API
var indexSettingsRequest = new
{
    index = new
    {
        lifecycle = new
        {
            name = "logs_policy"
        }
    }
};

var indexSettingsResponse = await client.Transport.RequestAsync<StringResponse>(
    new EndpointPath(Elastic.Transport.HttpMethod.PUT, "logs/_settings"),
    PostData.Serializable(indexSettingsRequest)
);

if (!indexSettingsResponse.ApiCallDetails.HasSuccessfulStatusCode)
{
    Console.WriteLine($"Error applying policy to index: {indexSettingsResponse.Body}");
}
else
{
    Console.WriteLine("Policy applied successfully to index.");
}
