Image variants


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).

This will required RBAC rules and deploy nfd-master (as a deployment) and nfd-worker (as daemonset) in the node-feature-discovery namespace.

NOTE: nfd-topology-updater is not deployed as part of the default overlay. Refer to the Master Worker Topologyupdater and Topologyupdater below.

Alternatively you can clone the repository and customize the deployment by creating your own overlays. See kustomize for more information about managing deployment configurations.

Overlays

The NFD repository hosts a set of overlays for different usages and deployment scenarios under deployment/overlays

Worker one-shot

Feature discovery can alternatively be configured as a one-shot job. The default-job overlay may be used to achieve this:

NUM_NODES=$(kubectl get no -o jsonpath='{.items[*].metadata.name}' | wc -w)

Kustomize

To deploy NFD with metrics enabled using kustomize, you can use the prometheus overlay.

Helm

By default metrics are enabled when deploying NFD via Helm. To enable Prometheus to scrape metrics from NFD, you need to pass the following values to Helm:

--set prometheus.enable=true

Helm

By default metrics are enabled when deploying NFD via Helm. To enable Prometheus to scrape metrics from NFD, you need to pass the following values to Helm:

--set prometheus.enable=true
 

For more info on Helm deployment, see Helm.

It is recommended to specify --set prometheus.prometheusSpec.podMonitorSelectorNilUsesHelmValues=false when deploying prometheus-operator via Helm to enable the prometheus-operator to scrape metrics from any PodMonitor.

or setting labels on the PodMonitor via the helm parameter prometheus.labels to control which Prometheus instances will scrape this PodMonitor.

Grafana dashboard

NFD contains an example Grafana dashboard. You can import examples/grafana-dashboard.json to your Grafana instance to visualize the NFD metrics.

      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-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.

      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:

      1. nfd-master
      2. nfd-worker

      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
      NodeFeatureAPI true Beta V0.14 v0.16
      NodeFeatureAPI true GA V0.17  
      DisableAutoPrefix false Alpha V0.16  
      NodeFeatureGroupAPI false 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

        labels:

      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.

      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

        labels:
           foo: bar
       

      will turn into feature.node.kubernetes.io/foo=bar node label. With DisableAutoPrefix set to true, no prefix is added and the label will be filtered out.

      Note that taint keys are not affected by this feature gate.

      -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 ..

      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.

      -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
       

      -config

      The -config flag specifies the path of the nfd-worker configuration file to use.

      Example:

      nfd-worker -config=/opt/nfd/worker.conf
       

      -options

      The -options flag may be used to specify and override configuration file options directly from the command line. The required format is the same as in the config file i.e. JSON or YAML. Configuration options specified via this flag will override those from the configuration file:

      Default: empty

      core.sleepInterval specifies the interval between consecutive passes of feature (re-)detection, and thus also the interval between node re-labeling. A non-positive value implies infinite sleep interval, i.e. no re-detection or re-labeling is done.

      core.featureSources

      core.featureSources specifies the list of enabled feature sources. A special value all enables all sources. Prefixing a source name with - indicates that the source will be disabled instead - this is only meaningful when used in conjunction with all. This option allows completely disabling the feature detection so that neither standard feature labels are generated nor the raw feature data is available for custom rule processing.

      Default: [all]

          Overview

          NFD provides multiple extension points for vendor and application specific labeling:

          • NodeFeature objects can be used to communicate "raw" node features and node labeling requests to nfd-master.
          • NodeFeatureRule objects provide a way to deploy custom labeling rules via the Kubernetes API.
          • local feature source of nfd-worker creates labels by reading text files.
          • custom feature source of nfd-worker creates labels based on user-specified rules.

          NodeFeature custom resource

          NodeFeature objects provide a way for 3rd party extensions to advertise custom features, both as "raw" features that serve as input to NodeFeatureRule objects and as feature labels directly.

          Note that RBAC rules must be created for each extension for them to be able to create and manipulate NodeFeature objects in their namespace.

          A NodeFeature example

          Consider the following referential example:

          NOTE: Consecutive runs of nfd-worker will update the labels on a given node. If features are not discovered on a consecutive run, the corresponding label will be removed. This includes any restrictions placed on the consecutive run, such as restricting discovered features with the -label-whitelist flag of nfd-master or core.labelWhiteList option of nfd-worker.

          User defined labels

          NFD has many extension points for creating vendor and application specific labels. See the customization guide for detailed documentation.

          Extended resources

          NFD is able to create extended resources, see the NodeFeatureRule CRD and its extendedResources field for more details.

          Note that NFD is not a replacement for the usage of device plugins.

          An example use-case for extended resources could be based on custom feature (created e.g. with feature files that exposes the node SGX EPC memory section size. This value will then be turned into an extended resource of the node, allowing PODs to request that resource and the Kubernetes scheduler to schedule such PODs to only those nodes which have a sufficient capacity of said resource left.

          NFD-GC (NFD Garbage-Collector) is preferably run as a Kubernetes deployment with one replica. It makes sure that all NodeFeature and NodeResourceTopology objects have corresponding nodes and removes stale objects for non-existent nodes.

          The daemon watches for Node deletion events and removes NodeFeature and NodeResourceTopology objects upon them. It also runs periodically to make sure no node delete event was missed and to remove any NodeFeature or NodeResourceTopology objects that were created without corresponding node. The default garbage collector interval is set to 1h which is the value when no -gc-interval is specified.

          Configuration

          In Helm deployments see garbage collector parameters for altering the nfd-gc configuration.

          NFD-Master


          NFD-Master is responsible for connecting to the Kubernetes API server and updating node objects. More specifically, it modifies node labels, taints and extended resources based on requests from nfd-workers and 3rd party extensions.

          NodeFeature controller

          The NodeFeature Controller uses NodeFeature objects as the input for the NodeFeatureRule processing pipeline. In addition, any labels listed in the NodeFeature object are created on the node (note the allowed label namespaces are controlled).

          NodeFeatureRule controller

          NFD-Master acts as the controller for NodeFeatureRule objects. It applies the rules specified in NodeFeatureRule objects on raw feature data and creates node labels accordingly. The feature data used as the input is received from nfd-worker instances through NodeFeature objects.

          Master configuration

          NFD-Master supports configuration through a configuration file. The default location is /etc/kubernetes/node-feature-discovery/nfd-master.conf, but, this can be changed by specifying the-config command line flag.

          Master configuration file is read inside the container, and thus, Volumes and VolumeMounts are needed to make your configuration available for NFD. The preferred method is to use a ConfigMap which provides easy deployment and re-configurability.

          The provided deployment methods (Helm and Kustomize) create an empty configmap and mount it inside the nfd-master containers.

          In Helm deployments, Master pod parameter master.config can be used to edit the respective configuration.

          In Kustomize deployments, modify the nfd-master-conf ConfigMap with a custom overlay.

          NOTE: dynamic run-time reconfiguration was dropped in NFD v0.17. Re-configuration is handled by pod restarts.

          See nfd-master configuration file reference for more details. The (empty-by-default) example config contains all available configuration options and can be used as a reference for creating a configuration.

          Deployment notes

          NFD-Master runs as a deployment, by default it prefers running on the cluster's master nodes but will run on worker nodes if no master nodes are found.

          For High Availability, you should increase the replica count of the deployment object. You should also look into adding inter-pod affinity to prevent masters from running on the same node. However note that inter-pod affinity is costly and is not recommended in bigger clusters.

          Note: When NFD-Master is intended to run with more than one replica, it is advised to use -enable-leader-election flag. This flag turns on leader election for NFD-Master and let only one replica to act on changes in NodeFeature and NodeFeatureRule objects.

          If you have RBAC authorization enabled (as is the default e.g. with clusters initialized with kubeadm) you need to configure the appropriate ClusterRoles, ClusterRoleBindings and a ServiceAccount for NFD to create node labels. The provided template will configure these for you.

          NFD-Topology-Updater


          NFD-Topology-Updater is preferably run as a Kubernetes DaemonSet. This assures re-examination on regular intervals and/or per pod life-cycle events, capturing changes in the allocated resources and hence the allocatable resources on a per-zone basis by updating NodeResourceTopology custom resources. It makes sure that new NodeResourceTopology instances are created for each new nodes that get added to the cluster.

          Because of the design and implementation of Kubernetes, only resources exclusively allocated to Guaranteed Quality of Service pods will be accounted. This includes CPU cores, memory and devices.

          When run as a daemonset, nodes are re-examined for the allocated resources (to determine the information of the allocatable resources on a per-zone basis where a zone can be a NUMA node) at an interval specified using the -sleep-interval option. The default sleep interval is set to 60s which is the value when no -sleep-interval is specified. The re-examination can be disabled by setting the sleep-interval to 0.

          Another option is to configure the updater to update the allocated resources per pod life-cycle events. The updater will monitor the checkpoint file stated in -kubelet-state-dir and triggers an update for every change occurs in the files.

          In addition, it can avoid examining specific allocated resources given a configuration of resources to exclude via -excludeList

          The provided deployment templates create an empty configmap and mount it inside the nfd-topology-updater containers.

          In Helm deployments, Topology Updater parameters toplogyUpdater.config can be used to edit the respective configuration.

          In Kustomize deployments, modify the nfd-worker-conf ConfigMap with a custom overlay.

          See nfd-topology-updater configuration file reference for more details. The (empty-by-default) example config contains all available configuration options and can be used as a reference for creating a configuration.

          NFD-Worker


          NFD-Worker is preferably run as a Kubernetes DaemonSet. This assures re-labeling on regular intervals capturing changes in the system configuration and makes sure that new nodes are labeled as they are added to the cluster. Worker connects to the nfd-master service to advertise hardware features.

          When run as a daemonset, nodes are re-labeled at an default interval of 60s. This can be changed by using the core.sleepInterval config option.

          Worker configuration

          NFD-Worker supports configuration through a configuration file. The default location is /etc/kubernetes/node-feature-discovery/nfd-worker.conf, but, this can be changed by specifying the-config command line flag. Configuration file is re-read whenever it is modified which makes run-time re-configuration of nfd-worker straightforward.

          Worker configuration file is read inside the container, and thus, Volumes and VolumeMounts are needed to make your configuration available for NFD. The preferred method is to use a ConfigMap which provides easy deployment and re-configurability.

          The provided deployment methods (Helm and Kustomize) create an empty configmap and mount it inside the nfd-master containers.

          In Helm deployments, Worker pod parameter worker.config can be used to edit the respective configuration.

          In Kustomize deployments, modify the nfd-worker-conf ConfigMap with a custom overlay.

          NOTE: dynamic run-time reconfiguration was dropped in NFD v0.17. Re-configuration is handled by pod restarts.

          See nfd-worker configuration file reference for more details. The (empty-by-default) example config contains all available configuration options and can be used as a reference for creating a configuration.

          Configuration options can also be specified via the -options command line flag, in which case no mounts need to be used. The same format as in the config file must be used, i.e. JSON (or YAML). For example:

          -options='{"sources": { "pci": { "deviceClassWhitelist": ["12"] } } }'
