To quickly view available command line flags execute nfd-topology-updater -help. In a docker container:
docker run gcr.io/k8s-staging-nfd/node-feature-discovery:master \
nfd-topology-updater -help
-h, -help
Print usage and exit.
-version
Print version and exit.
-config
The -config flag specifies the path of the nfd-topology-updater configuration file to use.
Default: /etc/kubernetes/node-feature-discovery/nfd-topology-updater.conf
Example:
nfd-topology-updater -config=/opt/nfd/nfd-topology-updater.conf
-no-publish
The -no-publish flag makes for a "dry-run" flag for nfd-topology-updater. NFD-Topology-Updater runs resource hardware topology detection normally, but NodeResourceTopology objects are not created or updated.
Default: false
Example:
nfd-topology-updater -no-publish
-oneshot
The -oneshot flag causes nfd-topology-updater to exit after one pass of resource hardware topology detection.
Default: false
Example:
nfd-topology-updater -oneshot -no-publish
-metrics
The -metrics flag specifies the port on which to expose Prometheus metrics. Setting this to 0 disables the metrics server on nfd-topology-updater.
Default: 8081
Example:
nfd-topology-updater -metrics=12345
-sleep-interval
The -sleep-interval specifies the interval between resource hardware topology re-examination (and CR updates). zero means no CR updates on interval basis.
Default: 60s
Example:
nfd-topology-updater -sleep-interval=1h
-watch-namespace
The -watch-namespace specifies the namespace to ensure that resource hardware topology examination only happens for the pods running in the specified namespace. Pods that are not running in the specified namespace are not considered during resource accounting. This is particularly useful for testing/debugging purpose. A "*" value would mean that all the pods would be considered during the accounting process.
Default: "*"
Example:
nfd-topology-updater -watch-namespace=rte
-kubelet-config-uri
The -kubelet-config-uri specifies the path to the Kubelet's configuration. Note that the URi could either be a local host file or an HTTP endpoint.
Default: https://${NODE_ADDRESS}:10250/configz
Example:
nfd-topology-updater -kubelet-config-uri=file:///var/lib/kubelet/config.yaml
-api-auth-token-file
The -api-auth-token-file specifies the path to the api auth token file which is used to retrieve Kubelet's configuration from Kubelet secure port, only taking effect when -kubelet-config-uri is https. Note that this token file must bind to a role that has the get capability to nodes/proxy resources.
Default: /var/run/secrets/kubernetes.io/serviceaccount/token
Example:
nfd-topology-updater -token-file=/var/run/secrets/kubernetes.io/serviceaccount/token
-podresources-socket
The -podresources-socket specifies the path to the Unix socket where kubelet exports a gRPC service to enable discovery of in-use CPUs and devices, and to provide metadata for them.
Default: /host-var/lib/kubelet/pod-resources/kubelet.sock
Example:
nfd-topology-updater -podresources-socket=/var/lib/kubelet/pod-resources/kubelet.sock
-pods-fingerprint
Enables compute and report the pod set fingerprint in the NRT. A pod fingerprint is a compact representation of the "node state" regarding resources.
Default: true
Example:
nfd-topology-updater -pods-fingerprint=false
-kubelet-state-dir
The -kubelet-state-dir specifies the path to the Kubelet state directory, where state and checkpoint files are stored. The files are mount as read-only and cannot be change by the updater. Enabled by default. Passing an empty string will disable the watching.
Default: /host-var/lib/kubelet
Example:
nfd-topology-updater -kubelet-state-dir=/var/lib/kubelet
