Updating Elasticsearch cluster settings

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 change the settings of the service account used to work with the cluster:

1. View the description of the update cluster CLI command:

   yc managed-elasticsearch cluster update --help
   

2. Specify the service account ID in the update cluster command:

   yc managed-elasticsearch cluster update <cluster_name_or_ID> \
     --service-account-id <service_account_ID>
   

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

Managed Service for Elasticsearch will run the service account update for the cluster.

1. Open the current Terraform configuration file with an infrastructure plan.

   For more information about creating this file, see Creating clusters.

2. In the service_account_id field, enter the service account ID:

   resource "yandex_mdb_elasticsearch_cluster" "<cluster_name>" {
     ...
     service_account_id = <service_account_ID>
   }
   

3. Make sure the settings are correct.

   1. Using the command line, navigate to the folder that contains the up-to-date Terraform configuration files with an infrastructure plan.

   2. Run the command:

      terraform validate
      

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

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.

   Time limits

   A Terraform provider sets the timeout for Managed Service for Elasticsearch cluster operations:

   • Creating a cluster, including by restoring one from a backup: 30 minutes.
   • Editing a cluster: 60 minutes.
   • Deleting a cluster: 15 minutes.

   Operations exceeding the set timeout are interrupted.

   How do I change these limits?

   Add the timeouts block to the cluster description, for example:

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

To change service account settings, use the update REST API method for the Cluster resource or the ClusterService/Update gRPC API call and provide the following in the request:

• Cluster ID in the clusterId parameter.

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

• ID of the service account used for cluster operations in the serviceAccountId parameter.

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 change the host class for the cluster:

1. View the description of the update cluster CLI command:

   yc managed-elasticsearch cluster update --help
   

2. Specify the host class you need with the Data node and Master node roles in the update cluster command:

   yc managed-elasticsearch cluster update <cluster_name_or_ID> \
     --datanode-resource-preset <class_of_hosts_with_the_Data_node_role> \
     --masternode-resource-preset <class_of_hosts_with_the_Master_node_role>
   

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

      --maintenance-window type=<maintenance_type>,`
                          `day=<day_of_week>,`
                          `hour=<hour> \
      --deletion-protection=<deletion_protection>
   

You can change the following settings:

• --plugins: List of Elasticsearch plugins available in the cluster. Plugins that are not on the list will be disabled.

• --maintenance-window: Maintenance window settings (including for disabled clusters), where type is the maintenance type:

  • anytime (default): Any time.
  • weekly: On a schedule. If setting this value, specify the day of week and the hour:
    • day: Day of week in DDD format: MON, TUE, WED, THU, FRI, SAT, or SUN.
    • hour: Hour (UTC) in HH format: 1 to 24.

• --deletion-protection: Protection of the cluster, its databases, and users against accidental deletion.

  Cluster deletion protection will not prevent a manual connection to a cluster to delete data.

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

1. Open the current Terraform configuration file with an infrastructure plan.

   For more information about creating this file, see Creating clusters.

   For a complete list of available Managed Service for Elasticsearch cluster configuration fields, see the Terraform provider documentation.

2. To set up the maintenance window (for disabled clusters as well), add the maintenance_window block to the cluster description:

   resource "yandex_mdb_elasticsearch_cluster" "<cluster_name>" {
