  1. New type OsContainerDesc which describes the member properties of a set of co-located container compute resources when these are realizing a VDU
    1. The osContainerDesc  element(s) are listed in the VNF Descriptor and referenced by the VDU element(s).  Each VDU may be made up of group of containers, often called a "pod".

      virtualStorageDesc

      M

      0..N

      Identifier (Reference to VirtualStorageDesc)

      Links to virtualStorageDesc-s of the Vdu. The storages represented by the linked VirtualStorageDesc-s are attached to the OS Container as volumes. Shall be present in case the OS container requires storage resources.

      monitoringParameters

      M

      0..N

      MonitoringParameter

      Specifies the virtualised resource related performance metrics on the OsContainerDesc level to be tracked by the VNFM. MonitoringParameter is defined in clause 7.1.11.3.

      NOTE:     Extended resources are to describe any type of resource provided by the container infrastructure. One example implementation of extended resources are “Extended Resources” in case the container infrastructure service is a Kubernetes® instance.


  2. New type MciopProfile which describes properties of the Managed Container Infrastructure Object Package (MCIOP) which are used during deployment of containerized workloads based on a MCIOP, associated to a VNF deployment flavour.   An MCIOP is a hierarchical aggregate of information objects for OS container management and orchestration. Multiple MCIOPs can be included in a VNF Package.  The MCIOP is expected to be realized by a Helm chart.
    1. Each VnfDf in the VNF Descriptor would list the appropriate mciopProfiles.
