| Attribute | Qualifier | Cardinality | Content | Description |
|---|---|---|---|---|
| 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, GPU compute, etc.). The intent of these labels is to serve as a set of values that can help in application placement decisions. clusterLabels follow the Kubernetes label key-value-nomenclature (https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/). It is recommended that labels follow a standardized standardised meaning e.g. for node features (https://kubernetes-sigs.github.io/node-feature-discovery/v0.9/get-started/features.html#table-of-contents) or are mutually agreed between ASD supplier and operators. Example: ClusterLabels |
| requiredPlugin | M | 0..N | String | A list of the names of the required K8s plugin (e.g. multus v3.8) |
