Initialize OpenSearch Cluster

To initialize an OpenSearch Cluster Database on the vDB system, you can follow these steps:

Step 1: Access https://vdb.console.vngcloud.vn/

Step 2: Select Cluster under the OpenSearch section, then select Create a cluster..

Step 3: On the OpenSearch Cluster initialization screen, you need to enter/select:

• Basic configuration:

  • OpenSearch Cluster name: a memorable name for the cluster. The cluster name must be between 5 and 50 characters long and can include characters a-z, A-Z, 0-9, '-'.

  • Tag: you can add tags to mark clusters according to your needs.

• Cluster specification

  • OpenSearch Version: select the OpenSearch Cluster version you want to use. Currently we are supporting 2 versions v2.15 and v2.17

  • Instance: select the CPU type and corresponding package you want to configure for all VMs (nodes) in each cluster.

  • Number of nodes: select the number of nodes (VMs) you want to use for the cluster. Currently we are providing options for 3, 5, 7, 9 nodes. If you want to create a cluster with more than 9 nodes, please contact GreenNode so we can assist you.

  • Encryption volume: select whether or not to use the encryption service for volumes used on the cluster. If you choose to use this option, you need to pay additional costs for encryption.

  • Storage type: select the disk type and IOPS you want to use.

  • Storage size: select the corresponding disk size.

• Network settings:

  • VPC: select a VPC you want to use. The selected VPC is the IP address range that the Cluster nodes will use to communicate.

  • Subnet: select a Subnet within the VPC you have selected. This is a smaller IP address range belonging to the VPC. Each node in the Cluster will be assigned an IP from this Subnet.

  • Public Allow CIDRs: enter the CIDR you allow to access the OpenSearch Dashboard and push logs to OpenSearch Received Logs.

• Access control methods:

  • Master user password: the system will automatically create the username master-user, you need to enter the master user password and remember to use this account to access the OpenSearch Dashboard as well as push logs to Received log.

• Cluster options:

  • Configuration group: by default, for each OpenSearch version, we will create a Default Configuration Group. You will not be able to change the parameters in this Default Configuration Group. If you want to change the default parameters, please create a new Configuration Group and edit it according to your needs.

• Plugins

  • Plugin: currently, vDB has automatically installed popular plugins in your OpenSearch Cluster under the Bundled Plugins section, for example kNN. You can refer to the list of default available plugins here. Additionally, you can also choose to install additional plugins by selecting plugins under the Additional Plugins section. Refer to the list of plugins available for installation here.
