Create a Kafka cluster
Last update:

Create a Kafka 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.

  5. Select a pool. Once created, the pool cannot be changed.

  6. Select RDBMS — Kafka.

  7. Select the Kafka version. Once created, the version cannot be changed.

  8. Select a line of configurations and specify the number of vCPUs, RAM size, and disk size.

    Once the cluster is created, you can change the configuration of nodes — scaling the cluster.

  9. Select or create a subnet:

    • private subnet — a subnet without access from the Internet. You can connect a static public IP address;
    • or public subnet — all addresses on a public subnet are accessible from the Internet.

    Addresses are assigned to each node in the cluster. Make sure that the number of addresses in the network is not less than the number of nodes in the cluster. Once a cluster is created, the network cannot be changed.

    A public IP address cannot be used.

    You can restrict the list of addresses from which access to the database cluster will be allowed.

  10. If you are creating a private subnet, specify the CIDR of the subnet.

  11. If you want to use DHCP for a private subnet, enable the DHCP toggle switch. Learn more about the DHCP protocol in the Selectel blog article DHCP Protocol Principles.

  12. If you are creating a public network, specify the subnet size.

  13. Optional: To change the DBMS settings, click Change. We recommend that you change the settings only when necessary — incorrectly selected values may reduce cluster performance.

  14. Check the price of the cluster.

  15. Click Create Cluster. The cluster will be ready for operation when it enters the ACTIVE status.
