Add a new NodeFeature CRD to the nfd Kubernetes API to communicate node
features over K8s api objects instead of gRPC. The new resource is
namespaced which will help the management of multiple NodeFeature
objects per node. This aims at enabling 3rd party detectors for custom
features.
In addition to communicating raw features the NodeFeature object also
has a field for directly requesting labels that should be applied on the
node object.
Rename the crd deployment file to nfd-api-crds.yaml so that it matches
the new content of the file. Also, rename the Helm subdir for CRDs to
match the expected chart directory structure.
Add auto-generated code for interfacing our CRD API. On top of this, a
CR controller can be implemented. This patch uses k8s/code-generator
for code generation. Run "make generate" in order to (re-)generate
everything. Path to the code-generator repository may need to be
specified:
K8S_CODE_GENERATOR=path/to/code-generator make apigen
Code-generator version 0.20.7 was used to create this patch. Install
k8s code-generator tools and clone the repo with:
git clone https://github.com/kubernetes/code-generator -b v0.20.7 <path/to/code-generator>
go install k8s.io/code-generator/cmd/...(at)v0.20.7
