Create an OpenSearch cluster

Create an OpenSearch cluster

  1. In the Control panel, on the top menu, click Products and select Cloud Databases.

  2. Click Create Cluster.

  3. Enter the name of the cluster.

  4. Select a region and pool. Once the cluster is created, you cannot change the region and pool.

  5. Select DBMS — OpenSearch.

Network⁠

An OpenSearch cluster can only be connected to a private subnet.You can create a new subnet or add a 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 Add New Subnet.

    2.2 Optional: Change the CIDR of the subnet.

    2.3 Optionally: enable the DHCP toggle switch.

    2.4 Optionally: Change the IP address of the default gateway.Addresses are assigned to each node in the cluster. Make sure that the number of addresses on the network is not less than the number of nodes in the cluster.

    2.5. Optional: Change the network where the subnet will be created — you can select an existing network or create a new one.Once the cluster is created the network cannot be changed.

Configuration of node groups⁠

  1. Configure a node group with the Manager role:

    1.1 Optional: change the name of the node group.

    1.2 Open the node group card.

    1.3 Select the configuration lineup.

    1.4 If you selected a ruler with arbitrary configurations, specify the number of vCPUs, RAM size, and disk size.

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

    1.6 Specify the number of nodes in the group.

    1.7. Optional: to make the nodes of the group accessible from the Internet, connect public IP addresses for them:

    • If you selected an existing private subnet, enable the Public toggle switch. The private subnet must meet the requirements;
    • If you are creating a new private subnet, connect the public IP addresses after the cluster is created.

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

  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.

Administrator user password⁠

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

    • at least 8 characters;
    • Latin letters of different cases;
    • figures;
