IBM z/OS Container Platform (zOSCP) 1.1 enhancements provide additional capabilities to manage the Kubernetes cluster upgrade process and to expand the networking support for multiple DVIPA (Dynamic Virtual IP Addressing) address ranges, are now available via PTFs.  

IBM z/OS Container Platform, zOSCP, utilizes industry-standard open- source technologies to build, deploy, run and manage containerized z/OS UNIX applications natively on z/OS. The product delivers a container runtime, Kubernetes orchestration and High Availability and load balancing capabilities to manage the availability and scalability demands of a Kubernetes cluster.

With this delivery, IBM is further enhancing the capability to support a production ready environment for running z/OS containers.

This IBM z/OS Container Platform 1.1 update is shipped with PTFs for the following APARs: OA67089, OA67178, OA67179, OA67180, OA67181, OA67182, OA67183, OA67184.

Enhancements

• Health check indicating when to upgrade the zOSCP Kubernetes open-source components 

• Networking support for multiple IP address ranges for ZCONTainer Dynamic Virtual IP Addresses (DVIPAs) with APAR PH63940 

• Open-source component upgrades:
• IBM z/OS for runC is upgraded to runC version 1.1.15.
• IBM z/OS for Conmon is upgraded to Conmon 2.1.12
• Kubelet for IBM z/OS is upgraded to version 1.31.2.
• cri-O for IBM z/OS is upgraded to version 1.31.1.
• IBM z/OS Control Plane Appliance (zCPA) is upgraded to 1.31.1.

KUBERNETES_VERSION health check alerts users on the need to upgrade by checking whether the currently running Kubernetes open-source components are at the latest available version.  For more information, see the health check setup step in the zOSCP product documentation under the “Running the z/OSMF workflow to perform the prerequisite steps required to join a z/OS system to a cluster as a worker node” section.

Networking enhancements for multiple VIPARANGE statement definitions which provides the ability to create a group of non-contiguous IP addresses, define different IP address groupings for different classes of users, as well as define different IP address groupings between users of Podman and users of Kubernetes. For more information refer to Requirements for IBM z/OS Container Platform IP addresses in the zOSCP product documentation.
