= Using the `ManagedClusterModule` CRD
|
|
|
|
Use the `ManagedClusterModule` Custom Resource Definition (CRD) to configure the deployment of kernel modules on spoke clusters.
|
|
This CRD is cluster-scoped, wraps a `Module` spec and adds the following additional fields:
|
|
|
|
[source,yaml]
|
|
----
|
|
apiVersion: hub.kmm.sigs.x-k8s.io/v1beta1
|
|
kind: ManagedClusterModule
|
|
metadata:
|
|
name: <my-mcm>
|
|
# No namespace, because this resource is cluster-scoped.
|
|
spec:
|
|
moduleSpec: <1>
|
|
selector: <2>
|
|
node-wants-my-mcm: 'true'
|
|
|
|
spokeNamespace: <some-namespace> <3>
|
|
|
|
selector: <4>
|
|
wants-my-mcm: 'true'
|
|
----
|
|
<1> `moduleSpec`: Contains `moduleLoader` and `devicePlugin` sections, similar to a `Module` resource.
|
|
|
|
<2> Selects nodes within the `ManagedCluster`.
|
|
<3> Specifies in which namespace the `Module` should be created.
|
|
<4> Selects `ManagedCluster` objects.
|
|
|
|
If build or signing instructions are present in `.spec.moduleSpec`, those pods are run on the hub cluster in the operator's namespace.
|
|
|
|
When the `.spec.selector matches` one or more `ManagedCluster` resources, then KMM-Hub creates a `ManifestWork` resource in the corresponding namespace(s). `ManifestWork` contains a trimmed-down `Module` resource, with kernel mappings preserved but all `build` and `sign` subsections are removed. `containerImage` fields that contain image names ending with a tag are replaced with their digest equivalent.
