NFD offers two variants of the container image. Released container images are available for x86_64 and Arm64 architectures.
Default
The default is a minimal image based on scratch and only supports running statically linked binaries.
For backwards compatibility a container image tag with suffix -minimal (e.g. gcr.io/k8s-staging-nfd/node-feature-discovery:master-minimal) is provided.
Full
This image is based on debian:bookworm-slim and contains a full Linux system for doing live debugging and diagnosis of the NFD images.
The container image tag has suffix -full (e.g. gcr.io/k8s-staging-nfd/node-feature-discovery:master-full).

- Custom resources
This software enables node feature discovery for Kubernetes. It detects hardware features available on each node in a Kubernetes cluster, and advertises those features using node labels and optionally node extended resources, annotations and node taints. Node Feature Discovery is compatible with any recent version of Kubernetes (v1.24+).
NFD consists of four software components:
- nfd-master
- nfd-worker
- nfd-topology-updater
- nfd-gc
NFD-Master
NFD-Master is the daemon responsible for communication towards the Kubernetes API. That is, it receives labeling requests from the worker and modifies node objects accordingly.
NFD-Worker
NFD-Worker is a daemon responsible for feature detection. It then communicates the information to nfd-master which does the actual node labeling. One instance of nfd-worker is supposed to be running on each node of the cluster,
NFD-Topology-Updater
NFD-Topology-Updater is a daemon responsible for examining allocated resources on a worker node to account for resources available to be allocated to new pod on a per-zone basis (where a zone can be a NUMA node). It then creates or updates a NodeResourceTopology custom resource object specific to this node. One instance of nfd-topology-updater is supposed to be running on each node of the cluster.
NFD-GC
NFD-GC is a daemon responsible for cleaning obsolete NodeFeature and NodeResourceTopology objects.
One instance of nfd-gc is supposed to be running in the cluster.
Feature Discovery
Feature discovery is divided into domain-specific feature sources:
- CPU
- Kernel
- Memory
- Network
- PCI
- Storage
- System
- USB
- Custom (rule-based custom features)
- Local (features files)
Each feature source is responsible for detecting a set of features which. in turn, are turned into node feature labels. Feature labels are prefixed with feature.node.kubernetes.io/ and also contain the name of the feature source. Non-standard user-specific feature labels can be created with the local and custom feature sources.

- Feature Gates · Node Feature Discovery
Feature Gates
Feature gates are a set of key-value pairs that control the behavior of NFD. They are used to enable or disable certain features of NFD. The feature gates are set using the -feature-gates command line flag or featureGates value in the Helm chart. The following feature gates are available:
Name Default Stage Since Until NodeFeatureAPItrue Beta V0.14 v0.16 NodeFeatureAPItrue GA V0.17 DisableAutoPrefixfalse Alpha V0.16 NodeFeatureGroupAPIfalse Alpha V0.16
NodeFeatureAPI
The NodeFeatureAPI feature gate enables the Node Feature API. When enabled, NFD will register the Node Feature API with the Kubernetes API server. The Node Feature API is used to expose node-specific hardware and software features to the Kubernetes scheduler. The Node Feature API is a beta feature and is enabled by default.
NodeFeatureGroupAPI
The NodeFeatureGroupAPI feature gate enables the Node Feature Group API. When enabled, NFD will register the Node Feature Group API with the Kubernetes API server. The Node Feature Group API is used to create node groups based on hardware and software features. The Node Feature Group API is an alpha feature and is disabled by default.
DisableAutoPrefix
The DisableAutoPrefix feature gate controls the automatic prefixing of names. When enabled nfd-master does not automatically add the default feature.node.kubernetes.io/ prefix to unprefixed labels, annotations and extended resources. Automatic prefixing is the default behavior in NFD v0.16 and earlier.
Note that enabling the feature gate effectively causes unprefixed names to be filtered out as NFD does not allow unprefixed names of labels, annotations or extended resources. For example, with the DisableAutoPrefix feature gate set to false, a NodeFeatureRule with

-version
Print version and exit.
-feature-gates
The -feature-gates flag is used to enable or disable non GA features. The list of available feature gates can be found in the feature gates documentation.
Example:
nfd-master -feature-gates NodeFeatureGroupAPI=true
-prune
The -prune flag is a sub-command like option for cleaning up the cluster. It causes nfd-master to remove all NFD related labels, annotations and extended resources from all Node objects of the cluster and exit.
-metrics
DEPRECATED: Will be removed in NFD v0.17 and replaced by -port.
The -metrics flag specifies the port on which to expose Prometheus metrics. Setting this to 0 disables the metrics server on nfd-master.
Default: 8081
Example:
nfd-master -metrics=12345
-instance
The -instance flag makes it possible to run multiple NFD deployments in parallel. In practice, it separates the node annotations between deployments so that each of them can store metadata independently. The instance name must start and end with an alphanumeric character and may only contain alphanumeric characters, -, _ or ..
Default: empty
Example:
nfd-master -instance=network

noPublish
noPublish option disables updates to the Node objects in the Kubernetes API server, making a "dry-run" flag for nfd-master. No Labels, Annotations, Taints or ExtendedResources of nodes are updated.
Default: false
Example:
noPublish: true
extraLabelNs
extraLabelNs specifies a list of allowed feature label namespaces. This option can be used to allow other vendor or application specific namespaces for custom labels from the local and custom feature sources, even though these labels were denied using the denyLabelNs parameter.
Default: empty
Example:
extraLabelNs: ["added.ns.io","added.kubernets.io"]
denyLabelNs
denyLabelNs specifies a list of excluded label namespaces. By default, nfd-master allows creating labels in all namespaces, excluding kubernetes.io namespace and its sub-namespaces (i.e. *.kubernetes.io). However, you should note that kubernetes.io and its sub-namespaces are always denied. This option can be used to exclude some vendors or application specific namespaces.
Default: empty
Example:
denyLabelNs: ["denied.ns.io","denied.kubernetes.io"]
autoDefaultNs
DEPRECATED: Will be removed in NFD v0.17. Use the DisableAutoPrefix feature gate instead.
The autoDefaultNs option controls the automatic prefixing of names. When set to true (the default in NFD version master) nfd-master automatically adds the default feature.node.kubernetes.io/ prefix to unprefixed labels, annotations and extended resources - this is also the default behavior in NFD v0.15 and earlier. When the option is set to false, no prefix will be prepended to unprefixed names, effectively causing them to be filtered out (as NFD does not allow unprefixed names of labels, annotations or extended resources). The default will be changed to false in a future release.
For example, with the autoDefaultNs set to true, a NodeFeatureRule with

Versions and deprecation
Supported versions
Node Feature Discovery follows semantic versioning where the version number consists of three components, i.e. MAJOR.MINOR.PATCH.
The most recent two minor releases (or release branches) of Node Feature Discovery are supported. That is, with X being the latest release, X and X-1 are supported and X-1 reaches end-of-life when X+1 is released.
Deprecation policy
Feature labels
Built-in feature labels and features are supported for 2 releases after being deprecated, at minimum. That is, if a feature label is deprecated in version X, it will be supported in X+1 and X+2 and may be dropped in X+3.
Configuration options
Command-line flags and configuration file options are supported for 1 more release after being deprecated, at minimum. That is, if option/flag is deprecated in version X, it will be supported in X+1 and may be removed in X+2.
The same policy (support for 1 release after deprecation) also applies to Helm chart parameters.
Kubernetes compatibility
Node Feature Discovery is compatible with Kubernetes v1.24 and later.

Prefixing a source name with - indicates that the source will be disabled instead - this is only meaningful when used in conjunction with all.

Custom Resources
Table of contents
NFD uses some Kubernetes custom resources.
NodeFeature
NodeFeature is an NFD-specific custom resource for communicating node features and node labeling requests. The nfd-master pod watches for NodeFeature objects, labels nodes as specified and uses the listed features as input when evaluating NodeFeatureRules. NodeFeature objects can be used for implementing 3rd party extensions (see customization guide for more details).
