|---|---|---|---|---|
| Id | M | 1 | String | Asd local unique name for the enhanceClusterCapabilities instance |
| minKernelVersion | M | 1 | String | Describes the minimal required Kernel version, e.g. 4.15.0. Coded as displayed by linux command uname –r |
| requiredKernelModules | M | 0..1 | List of String | Required kernel modules are coded as listed by linux lsmod command, e.g. ip6_tables, cryptd, nf_nat etc. |
| conflictingKernelModules | M | 0..1 | List of String | Kernel modules, which must not be present in the target environment. The kernel modules are coded as listed by linux lsmod command, e.g. ip6_tables, cryptd, nf_nat etc. Example: Linux kernel SCTP module, which would conflict with use of proprietary user space SCTP stack provided by the application. |
| requiredCRDs customResourceRequirements | M | 0..1 | List of String | List the required CRDs and their versions in the target environment. The list shall include those CRDs which are not delivered with the application.

| clusterLabels | M | 0..1 | List of String | This attribute allows to associate arbitrary labels to clusters. These can indicate special infrastructure capabilities (e.g., NW acceleration, GPGPU compute, etc.). The intent of these labels is to serve as a set of values that can help in application placement decisions. This can be specified with the attribute -m: Mandatory, means deployment is not attempted if such support is not available in the target system -p: As preference - it means orchestrator will try to select a system with specific requirements, but if not found it will attempt deployment in a system not having such HW. |
| secondaryInterfacePlugin | M | 0..1 | String | The plug-in name / revision of the operator to handle secondary interface (e.g. Multus-CNI, v3.8) |
