Create an OpenSearch cluster

1. In the Dashboard, from the top menu, click Products and select Managed Databases.

2. Click Create cluster.

3. Enter the cluster name.

4. Select a location. You cannot change the location after the cluster is created.

5. Select the database engine — OpenSearch.

6. Select an OpenSearch version.

7. Fill in the sections:

   • Network;
   • optional: Security;
   • Node group configuration;
   • optional: Logging;
   • Administrator password.

8. Check the price of the Managed Databases cluster.

9. Click Create cluster.

Network

An OpenSearch cluster can only be connected to a private subnet. You can create a new subnet or add the cluster to an existing one.

1. To add the cluster to an existing private subnet, in the Subnet field, select an existing subnet.

2. To create a new private subnet:

   2.1. In the Subnet field, select New private subnet.

   2.2. Optional: change the subnet CIDR.

   2.3. Optional: change the network in which the subnet will be created — you can select an existing network or create a new one. After the cluster is created, the network cannot be changed.

Optional: Security

Select security groups to filter incoming and outgoing cluster traffic. If the Security section is missing, traffic filtering (port security) is disabled in the cluster network. If traffic filtering is off, all traffic will be allowed.

Node group configuration

1. Configure the node group with the Manager role:

   1.1. Optional: change the node group name.

   1.2. Open the node group card.

   1.3. Select a configuration line.

   1.4. If you selected a line with custom configurations, select a disk type, specify the number of vCPUs, RAM size, and disk size.

   1.5. If you selected a line with fixed configurations, select a configuration.

   1.6. Specify the number of nodes in the group.

   1.7. Optional: to make the nodes in the group accessible from the internet, assign public IP addresses to them:

   • if you selected an existing private subnet, select the Connect public access checkbox. You can connect public IP addresses if the private subnet meets the requirements. If the subnet does not meet the requirements, you can connect public IP addresses after creating the cluster;

   • if you are creating a new private subnet, connect public IP addresses after creating the cluster.

   Public IP addresses are automatically assigned to all nodes in the group — a separate address for each node.

2. Repeat steps 1.1–1.7 for the node group with the Data role.

3. Optional: to add additional node groups, click Add node group, and repeat steps 1.1–1.7.

Optional: Logging

To access cluster logs, enable logging. Logging uses part of the cluster's computing resources.

1. Select the checkbox Collect technical cluster logs into the log service.

2. Select a log group or create a new one.

3. If you selected a new group, enter its name.

Administrator password

1. Enter the user password or click Generate. The password must contain:

   • at least 8 characters;
   • uppercase and lowercase Latin letters;
   • digits;
   • special characters — !?@$%&*..

2. Copy and save the user password — it cannot be viewed in the Dashboard after the cluster is created.
