- New type OsContainerDesc which describes the member properties of a set of co-located container compute resources when these are realizing a VDU
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".

Description
osContainerDescId
M
1
Identifier
Unique identifier of this OsContainerDesc in the VNFD.
requestedCpuResources
M
0..1
Integer
Number of CPU resources requested for the container (e.g. in milli-CPU-s)
requestedMemoryResources
M
0..1
Number
Amount of memory resources requested for the container (e.g. in MB).
requestedEphemeralStorageResources
M
0..1
Number
Size of ephemeral storage resources requested for the container (e.g. in GB).
extendedResourceRequests
M
0..N
Not specified
An array of key-value pairs of extended resources required by the container.
See note.
cpuResourceLimit
M
0..1
Integer
Number of CPU resources the container can maximally use (e.g. in milli-CPU).
memoryResourceLimit
M
0..1
Number
Amount of memory resources the container can maximum use (e.g. in MB).
ephemeralStorageResourceLimit
M
0..1
Number
Size of ephemeral storage resources the container can maximum use (e.g. in GB).
swImageDesc
M
1
Identifier (Reference to SwImageDesc)
Describes the software image realizing this OS container.
bootData
M
0..1
Not specified
Contains a string or a URL to a file contained in the VNF package used to customize a container resource at boot time. The bootData may contain variable parts that are replaced by deployment specific values before being sent.
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.
- 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.
Each VnfDf in the VNF Descriptor would list the appropriate mciopProfiles.

Description
mciopId
M
1
Identifier
Identifies the MCIOP in the VNF package.
deploymentOrder
M
0..1
Integer
Indicates the order in which this MCIOP shall be deployed in relation to other MCIOPs. A lower value specifies an earlier deployment.
affinityOrAntiAffinityGroupId
M
0..N
Identifier (Reference to AffinityOrAntiAffinityGroup)
References the affinity or anti-affinity group(s) the MCIOP belongs to.
See note.
associatedVdu
M
0..N
Identifier (Reference to Vdu)
List of VDUs which are associated to this MCIOP and which are deployed using this MCIOP.
NOTE: Each identifier references an affinity or anti-affinity group which expresses affinity or anti-affinity relationships between the containerized workloads to be created using this MCIOP and the containerized workloads to be created using other MCIOP(s) in the same group.
- New types VirtualCpd, AdditionalServiceData, and which is a ServicePortData
VirtualCpd - A type of Cpd that describes a requirement to create a virtual connection point allowing the access to a number of VNFC instances (based on their respective VDUs).

AdditionalServiceData
Additional service identification data of the VirtualCp exposed to NFV-MANO.
(inherited attributes)
All attributes inherited from Cpd.
See note.NOTE: If this VirtualCp represents a load balancing virtual IP address of a VNFC realized by one or a set of OS containers and the IP address is configurable in the declarative descriptor of the corresponding MCIO, the attribute iPAddressAssignment shall be set to value=true in the L3AddressData.
