Create an OpenSearch cluster

  1. In the Control panel, on 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 DBMS — OpenSearch.

  6. Select an OpenSearch version.

  7. Fill in the blocks:

  8. Check the Managed Database cluster price.

  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 an existing private subnet, in the Subnet field, select an existing subnet.

  2. To add 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. The network cannot be changed after the cluster is created.

Optional: Security

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

Node group configuration

  1. Configure the manager node group:

    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 the 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 group nodes accessible from the internet, attach public IP addresses to them:

    • if you have selected an existing private subnet, enable the Public access toggle. The private subnet must meet the requirements;
    • if you are creating a new private subnet, attach public IP addresses after cluster creation.

    IP addresses are automatically assigned to all nodes in the group.

  2. Repeat steps 1.1–1.7 for the data node group.

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

Optional: Logging

To have access to cluster logs, enable logging. Logging uses a portion of the cluster's computing resources.

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

  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;
    • latin letters of different cases;
    • digits;
    • special characters — !?@$%&*..

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