Node feature discovery for Kubernetes
237494463b
Support the new NodeFeatures object of the NFD CRD api. Add two new
command line options to nfd-worker:
-kubeconfig specifies the kubeconfig to use for
connecting k8s api (defaults to empty which
implies in-cluster config)
-enable-nodefeature-api enable the NodeFeature CRD API for
communicating node features to nfd-master,
will also automatically disable gRPC
(defgault to false)
No config file option for selecting the API is available as there should
be no need for dynamically selecting between gRPC and CRD. The
nfd-master configuration must be changed in tandem and it is safer (and
avoid awkward configuration races) to configure the whole NFD deployment
at once.
Default behavior of nfd-worker is not changed i.e. NodeFeatures object
creation is not enabled by default (but must be enabled with the command
line flag).
The patch also updates the kustomize and Helm deployment, adding RBAC
rules for nfd-worker and updating the example worker configuration.
