OpenSearch Service examples using SDK for Kotlin

The following code examples show you how to perform actions and implement common scenarios by using the AWS SDK for Kotlin with OpenSearch Service.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios.

Each example includes a link to the complete source code, where you can find instructions on how to set up and run the code in context.

suspend fun createNewDomain(domainNameVal: String?) {
    val clusterConfigOb =
        ClusterConfig {
            dedicatedMasterEnabled = true
            dedicatedMasterCount = 3
            dedicatedMasterType = OpenSearchPartitionInstanceType.fromValue("t2.small.search")
            instanceType = OpenSearchPartitionInstanceType.fromValue("t2.small.search")
            instanceCount = 5
        }

    val ebsOptionsOb =
        EbsOptions {
            ebsEnabled = true
            volumeSize = 10
            volumeType = VolumeType.Gp2
        }

    val encryptionOptionsOb =
        NodeToNodeEncryptionOptions {
            enabled = true
        }

    val request =
        CreateDomainRequest {
            domainName = domainNameVal
            engineVersion = "OpenSearch_1.0"
            clusterConfig = clusterConfigOb
            ebsOptions = ebsOptionsOb
            nodeToNodeEncryptionOptions = encryptionOptionsOb
        }

    println("Sending domain creation request...")
    OpenSearchClient { region = "us-east-1" }.use { searchClient ->
        val createResponse = searchClient.createDomain(request)
        println("Domain status is ${createResponse.domainStatus}")
        println("Domain Id is ${createResponse.domainStatus?.domainId}")
    }
}

    val request =
        UpdateDomainConfigRequest {

    println("Sending domain update request...")
    OpenSearchClient { region = "us-east-1" }.use { searchClient ->
        val updateResponse = searchClient.updateDomainConfig(request)
        println("Domain update response from Amazon OpenSearch Service:")
        println(updateResponse.toString())
    }
