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..N | String | Required kernel modules are coded as listed by linux lsmod command, e.g. ip6_tables, cryptd, nf_nat etc. |
conflictingKernelModules | M | 0..N | 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 | 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: |
>kind | M | 0..1 | String | Kind of the custom resource |
>apiVersion | M | 0..1 | String | apiVersion of the custom resource |
clusterLabels | M | 0..N | KeyValuePairs | 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 standardised meaning e.g. for node features (https://kubernetes-sigs.github.io/node-feature-discovery/v0.9/get-started/features.html#table-of-contents). Example: ClusterLabels |
requiredPlugin | M | 0..N | Structure (inlined) | A list of the names and versions of the required K8s plugin (e.g. multus v3.8) |
>requiredPluginName | M | 0..1 | String | The names of the required K8s plugin (e.g. multus) |
>requiredPluginVersion | M | 0..1 | String | Version The version of the required plugin (e.g. 3.8) |
