Use either the list REST API method for the Cluster resource or the ClusterService/List gRPC API call.

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

To get information about a Managed Service for Kubernetes cluster:

1. If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

2. Create a Terraform configuration file with a description of the yandex_kubernetes_cluster data source in the data section and the requested parameters in the output sections (one per section). For example:

   data "yandex_kubernetes_cluster" "my_cluster" {
     cluster_id = "<cluster_ID>"
   }
   
   output "external_v4_endpoint" {
     value = data.yandex_kubernetes_cluster.my_cluster.master.0.external_v4_endpoint
   }
   

   Where:

   • external_v4_endpoint: Name of the variable whose value will appear in the result.
   • data.yandex_kubernetes_cluster.my_cluster.master.0.external_v4_endpoint: Requested parameter. In our case, it is the cluster’s public IP address.

   For the list of cluster parameters you can request this way, see this Terraform provider guide.

   Tip

   To request all available information about a cluster, add the following output section to the file:

   output "kubernetes_cluster" {
     value = data.yandex_kubernetes_cluster.my_cluster
   }
   

3. Make sure the configuration files are correct:

   1. In the command line, navigate to the folder containing the current Terraform configuration files.

   2. Run this command:

      terraform validate
      

      Terraform will display any configuration errors detected in your files.

4. Run this command:

   terraform apply
   

   Terraform will display output variables in the terminal.

5. To check the result, run the following command by specifying the required variable, e.g.:

   terraform output external_v4_endpoint
   

   Result:

   "https://158.1**.***.***"
   

To get detailed information about a Kubernetes cluster, use the get REST API method for the Cluster resource or the ClusterService/Get gRPC API call.
