How to Create OpenSearch Clusters

OpenSearch is an open-source search and analytics suite which serves as a centralized location to manage logs forwarded from other resources, such as databases and Droplets.

Create a Database Cluster Using the CLI

To create a database using doctl, you need to provide values for the --engine, --region, and --size flags. Use the doctl databases options engines, doctl databases options regions, and doctl databases options slugs commands, respectively, to get a list of available values.
How to Create a Database Using the DigitalOcean CLI
  1. Install doctl, the DigitalOcean command-line tool.

  2. Create a personal access token and save it for use with doctl.

  3. Use the token to grant doctl access to your DigitalOcean account.

              doctl auth init
  4. Finally, run doctl databases create. Basic usage looks like this, but you can read the usage docs for more details:

                doctl databases create <name> [flags]

    The following example creates a database cluster named example-database in the nyc1 region with a single 1 GB node:

                  doctl databases create example-database --region nyc1 --size db-s-1vcpu-1gb --num-nodes 1

Create a Database Cluster Using the API

To create a database using the API, you need to provide values for the engine, region, and size fields, which specify the database’s engine, its datacenter, and its configuration (number of CPUs, amount of RAM, and hard disk space). Use the /v2/databases/options endpoint to get a list of available values.
How to Create a Database Using the DigitalOcean API
  1. Create a personal access token and save it for use with the API.

  2. Send a POST request to


    Using cURL:

                    curl -X POST \
      -H "Content-Type: application/json" \
      -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
      -d '{"name": "backend", "engine": "pg", "version": "14", "region": "nyc3", "size": "db-s-2vcpu-4gb", "num_nodes": 2, "storage_size_mib": 61440, "tags": ["production"]}' \


    Using Godo, the official DigitalOcean V2 API client for Go:

                    import (
    func main() {
        token := os.Getenv("DIGITALOCEAN_TOKEN")
        client := godo.NewFromToken(token)
        ctx := context.TODO()
        createRequest := &godo.DatabaseCreateRequest{
            Name:       "backend",
            EngineSlug: "pg",
            Version:    "14",
            Region:     "nyc3",
            SizeSlug:   "db-s-2vcpu-4gb",
            NumNodes:   2,
            StorageSizeMiB : 61440,
        cluster, _, err := client.Databases.Create(ctx, createRequest)


                    import os
    from pydo import Client
    client = Client(token=os.environ.get("DIGITALOCEAN_TOKEN"))
    create_req = {
      "name": "backend",
      "engine": "pg",
      "version": "14",
      "region": "nyc3",
      "size": "db-s-2vcpu-4gb",
      "num_nodes": 2,
      "storage_size_mib": 61440,
      "tags": [
    create_resp = client.databases.create_cluster(body=create_req)

Create a Database Cluster Using the Control Panel

You can create an OpenSearch database cluster from the Create menu by selecting Databases. This takes you to the Create a Database page.

The Create menu

Choose a datacenter

In the Choose a datacenter section, select the datacenter for your database cluster.

The datacenter selection portion of the databases create page

This page lists the datacenters in which you currently have the most resources. The number of resources you have in each datacenter is listed to the right as X resources. Hover over this text to see the specific resources you have in that datacenter.

For the best performance, create your database in the same datacenter as your other DigitalOcean resources.

Each region has one or more datacenters, each with a different VPC network. By including resources in the same datacenter, they all gain access to the same private networking interface, which reduces lag and keeps traffic between them from being routed over the public internet.

Choose a database engine

In the Choose a database engine section, choose OpenSearch.

The database engine selection portion of the databases create page

We currently support OpenSearch v1 and v2. You cannot change the OpenSearch version after creating a cluster.

Choose a cluster configuration

In the Choose a cluster configuration section, select the machine type and the number and size of the database nodes.

  • Basic - Shared CPU
  • General Purpose - Dedicated CPU*
  • Memory-Optimized - Dedicated CPU*

For Basic plans, you can choose 1 or 3 nodes. For General Purpose and Memory-Optimized plans, you can choose 1, 3, 6, 9, or 15 nodes.

Each option lists its combined monthly cost, equivalent hourly cost, and node specifications. For more options, click See all plans.

The Choose a cluster configuration section of the Create a database page displaying the node size and monthly cost

After creation, you can increase the number or size of database nodes at any time. However, you cannot downsize nodes to have less storage than the current storage the cluster is currently using.

Choose a storage size

In the Choose a storage size section, you can specify the storage size by clicking the up or down arrow or by entering your desired storage amount, in increments of 10 GB, up to the maximum listed in the storage range. Each 10 GB of storage you add costs an additional $2 per month.

You can increase your storage at any time. However, You cannot reduce the amount of added storage in a cluster lower than the amount of storage you are currently using in your cluster.

Finalize and create

In this section, enter the following information:

  • Choose a name: Use the automatically-generated name for the database or choose a custom name. Names must be unique, be between 3 and 63 characters long, and only contain alphanumeric characters, dashes, and periods.

  • Select a project: Use the default project or choose another one.

  • Tags: Add a tag in the text box and press enter. Tags can only contain letters, numbers, colons, dashes, and underscores.

The Finalize and Create section of the Create a database page

After creation, you can edit the database’s tags or move it to another project; however, you can’t rename it.

Click the Create a Database Cluster button.

Clusters typically take five minutes or more to provision, but you can complete important configuration tasks such as restricting inbound connections while the cluster is provisioning.
