Managing IP Reservations for a Cluster

Not Oracle Cloud Infrastructure This topic does not apply to Oracle Cloud Infrastructure.

You can optionally create IP reservations prior to provisioning an Oracle Data Hub Cloud Service cluster. If you create a cluster that uses a reserved IP address, you can reuse the same IP address again later, but only after you delete the cluster.

Creating an IP Reservation

When you create a cluster, Oracle Cloud automatically reserves and assigns public IP addresses to the nodes in the cluster. Alternatively, you can create your own IP reservations prior to creating a cluster. You can reserve IP addresses, and assign them to nodes within your Oracle Data Hub Cloud Service clusters. These reserved IP addresses are persistent.

If you intend to create a cluster in multiple regions, then you must create separate IP reservations for each region.

The number of IP reservations that you create must be equal to or greater than the number of nodes that you expect to create in your cluster.

Note:

If you are creating your first IP reservation, then you must access the IP Reservations page from the Create New Instance: Service Details Page of the instance creation wizard. Locate the Reserved IPs field and click the gear icon.
  1. Access your service console.
  2. Click the IP Reservations tab.
  3. Click Create.
  4. In the Name field, enter a name for the IP reservation.
  5. In the Region field, select the Oracle Cloud region in which you want to use this IP reservation.
  6. If you intend to use this reservation for an instance that you attach to an IP network, select the On IP Network check box.
    If you leave this check box deselected, the IP reservation can be assigned to only an instance that you attach to the shared network.
  7. Click OK.
  8. To verify if an IP address is successfully reserved, click Refresh Refresh icon.
    The IP reservation is ready to use when its status is UNUSED.

Deleting an IP Reservation

You can delete reserved IP addresses that are no longer needed for Oracle Data Hub Cloud Service.

When you delete an IP reservation, the IP address returns to the pool of available IP addresses in Oracle Cloud. You cannot delete an IP reservation that is in use. If you assign an IP reservation to a cluster, then you must delete the cluster before you can delete the IP reservation.

  1. Access your service console.
  2. Click the IP Reservations tab.
  3. Locate the IP reservation that you want to delete.
    To find an IP reservation, enter a full or partial name of the reservation or its region, and then click Search Search icon.
  4. Beside the IP reservation, click Delete Delete icon.
  5. When prompted for confirmation, click OK.
