| Attribute | Qualifier | Cardinality | Content | Description |
|---|---|---|---|---|
| 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 may conflict with use of proprietary user space SCTP stack provided by the application. |
requiredCustomResources >kind >apiVersion | M | 0..N | Structure (inlined) | List the required custom resources types in the target environment, identifying each by the "kind" and "apiVersion" field in the K8S resource manifests and in the application. The list shall include those custom resource types which are not delivered with the application. Example: |
| 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. |
| requiredPodAnnotations | M | 0..N | String | Annotations required to be supported. Example that list requirement for Kubernetes cluster infrastructure support for the Multus network attachment annotations: requiredPodAnnotations: {"k8s.v1.cncf.io/networks", ... } |
