Create a Kafka cluster

Last update:

  1. In the Dashboard, 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. Optional: To access cluster logs, enable logging. Logging uses a portion of the cluster's compute resources.

    9.1.Check the Collect cluster technical logs to log service checkbox.

    9.2.Select a log group or create a new group.

    9.3.If you have selected a new group, enter its name.

  10. 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.

    Make sure that at least one address is available on the network. 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.

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

  12. 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.

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

  14. Optional: Check the security groups to filter inbound and outbound cluster traffic. If the Security block is unchecked , port security is disabled on the cluster network . With traffic filtering disabled, all traffic will be allowed.

  15. Optional: To view the default values of the DBMS settings or to change them, click Change. We recommend that you change the settings values only when necessary — incorrect values may reduce cluster performance.

  16. Check the price of the cluster.

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