v0.16

Changelog

NodeFeatureGroup API

The NodeFeatureGroup custom resource was added to the NFD API. The NodeFeatureGroup API enables the creation of node groups based on features discovered by NFD. The API is an alpha feature and is disabled by default and can be enabled with the NodeFeatureGroupAPI feature gate.

See documentation for more details.

Feature gates

NFD adapted the concept of feature gates from Kubernetes to introduce and stabilize new features in a controlled way. See the documentation for more details. Two existing features (NodeFeature API and disabling label auto-prefixing) were converted into feature gates.

Deprecations

Upcoming changes

Support for hooks is deprecated since v0.12.0 and will be completely dropped in the NFD v0.17.

RDT feature labels removed

The feature.node.kubernetes.io/cpu-rdt.* feature labels that were deprecated in NFD v0.13 were removed. RDT features are still available for use in NodeFeatureRules for custom labels.

Deprecated flags and options

The autoDefaultNs config file option of nfd-master is deprecated and will be removed in NFD v0.17. Superseded by the DisableAutoPrefix feature gate (featureGates.DisableAutoPrefix Helm parameter).

The -enable-nodefeature-api command line flag of nfd-master and nfd-worker and the corresponding enableNodeFeatureApi Helm chart parameter have been deprecated and will be removed in NFD v0.17. Superseded by the NodeFeature API feature gate (featureGates.NodeFeatureAPI Helm parameter).

The -crd-controller command line flag of nfd-master is deprecated and will be removed with the gRPC API in a future release.

Miscellaneous

Network devices

Discover speed of virtual network interfaces.

DMI

Added support for detecting DMI attributes from /sys/devices/virtual/dmi/id/. In v0.16 only sys_vendor discovered, available as system.dmiid.sys_vendor feature for use in NodeFeatureRules.

Swap

Discover the availability of swap on the node. Available as memory.swap.enabled feature for use in NodeFeatureRules.

Helm chart

Now all nodes are cleaned up (feature labels, annotations, extended resources and taints are removed) after uninstalling NFD using a post-delete hook.

The Helm chart now sets resource requests (cpu and memory) for NFD pods. Users may want to adjust these for their cluster. An option to set the pod priority class was added. See Helm chart parameters in the documentation).

Container health

A gRPC health server was added to the nfd-master, nfd-worker and nfd-topology-updater daemons. Deployments (Helm and kustomize) configure container liveness and readiness probes to use that for health checking.
