See the documentation for more details

Helm

The Helm chart is now served from the registry.k8s.io OCI registry at registry.k8s.io/nfd/charts/node-feature-discovery. One liner installation with

helm install -n node-feature-discovery nfd oci://registry.k8s.io/nfd/charts/node-feature-discovery --version 0.18.0 --create-namespace

[!IMPORTANT]
The legacy Helm repository at https://kubernetes-sigs.github.io/node-feature-discovery/charts is still available, but will be deprecated and stop getting updated in a future release. Users are encouraged to migrate to the OCI registry.

The release contains numerous small improvements and fixes to the Helm chart and its documentation, including:

• Configurable DNS policy (#​2025)
• Configurable PodDisruptionBudget (#​2148)
• Configurable UpdateStrategy for nfd-worker (#​2157)
• Global global.imagePullSecrets parameter (#​2191)
• Fix for running with OwnerReferencesPermissionEnforcement validating webhook enabled (#​2006)
• Post-delete hook: option to disable (#​2076) and configurable image pull secret (#​2082)

Deprecations

The deprecated autoDefaultNs configuration parameter of nfd-master was removed.

Toleration for the deprecated node-role.kubernetes.io/master:NoSchedule taint and affinity to the deprecated node-role.kubernetes.io/master label have been removed from the default nfd-master deployment manifests. If you still need these, they need to be explicitly added to the deployment (master.tolerations and master.affinity in the Helm chart).

[!IMPORTANT]
In v0.18.0 the DisableAutoPrefix feature is still alpha and disabled by default. NFD adds feature.node.kubernetes.io/ prefix to all unprefixed label, annotation and extended resource names. When DisableAutoPrefix is enabled (will be default in a future release), NFD will not add the default prefix automatilly (and add unprefixed names, verbatim). Users are stronglycencouraged to start using fully qualified names (with the prefix) for allccustom labels, annotations and extended resources.

Miscellaneous

Scalability

The release contains improvements and fixes to NFD scalability in larger clusters.

NodeFeatureRules

Label templating

The label templates in NodeFeatureRules now support sprig functions, greatly enhancing their flexibility.

New comparison operators

New comparison operators Ge, Le and GeLe were added (#​2085).

Type field in MatchExpressions

New Type field was added to MatchExpressions, allowing to specify the type of the value being compared (#​2096). Currently supported types are empty value (the default) and version. Use of version type enables version-aware comparisons.

CPU features

Support for new CPUID flags were added, including AMXCOMPLEX, AMXTRANSPOSE and AMXTF32.

Memory features

NFD now detects availability of hugepages and reports them as memory-hugepages.enabled and hugepages-<page-size>features (#​2056).

Network features

Detection of the MTU of network devices was added (#​2044).

Metrics and health endpoints

The gRPC health endpoint was replaced by an HTTP healthz endpoint in all NFD daemons. In addition, both the metrics and healthz endpoints are now served on the same port (configurable with --port, default 8080).
