Deleting a Greenplum® cluster

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

To delete a cluster, run the command:

yc managed-greenplum cluster delete <cluster_name_or_ID>

You can request the cluster ID and name with a list of clusters in the folder.

To delete the infrastructure created with Terraform:

1. In the terminal window, go to the directory containing the infrastructure plan.

2. Delete the Terraform configuration file of the cluster.

3. Make sure the Terraform configuration files are correct using this command:

   terraform validate
   

   If there are any errors in the configuration files, Terraform will point them out.

4. Confirm updating the resources.

   1. Run the command to view planned changes:

      terraform plan
      

      If the resource configuration descriptions are correct, the terminal will display a list of the resources to modify and their parameters. This is a test step. No resources are updated.

   2. If you are happy with the planned changes, apply them:

      1. Run the command:

         terraform apply
         

      2. Confirm the update of resources.

      3. Wait for the operation to complete.

   All the resources described in the configuration file will be deleted.

resource "yandex_mdb_clickhouse_cluster" "<cluster_name>" {
  ...
  timeouts {
    create = "1h30m" # 1 hour 30 minutes
    update = "2h"    # 2 hours
    delete = "30m"   # 30 minutes
  }
}

To delete a cluster, use the delete REST API method for the Cluster resource or the ClusterService/Delete gRPC API call and provide the cluster ID in the clusterId request parameter.

You can get the cluster ID with a list of clusters in the folder.
