The Recovery Kit for Oracle Cloud Infrastructure (RK for OCI) manages the assignment of secondary private IP addresses to Virtual Network Interface Cards (VNICs) so that clients on the OCI can connect to the LifeKeeper-protected IP resources (virtual IP addresses).

https://docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingIPaddresses.htm

To use a virtual IP address on OCI, you need to assign the target IP address to the VNIC of the active node in addition to assigning the IP address on the OS.

In LifeKeeper, the IP Recovery Kit assigns IP addresses on the OS.

The RK for OCI runs the OCI CLI on the cluster node and manages the assignment of secondary private IP addresses to the VNICs of the active node on the OCI.

The RK for OCI also monitors whether the protected IP address is assigned to the specified VNIC on the active node.

When the active node fails, the RK for OCI assigns an IP address to the VNIC of the standby node and makes the virtual IP address available.
