Node Feature Discovery (NFD)
Node Feature Discovery (NFD) software detects the hardware features that are available on each node in a Kubernetes cluster, and advertises the detected features through node labels. NFD shares this information with kube-scheduler, which uses the information in its work.
Configuration
MKE 4 supports the deployment of NFD as an add-on. Enabled by default, the NFD
add-on deploys as a helm chart, version 0.16.1
in the mke
namespace.
ℹ️
The MKE 4 configuration file does not expose
parameters for the NFD add-on.
Obtain the default configuration file:
mkectl init
Apply the configuration:
mkectl apply -f [config-file]
Verify the successful deployment of NFD in the cluster:
kubectl get pods,services,deployments -n mke -l app.kubernetes.io/name=node-feature-discovery
Sample output:
NAME READY STATUS RESTARTS AGE pod/node-feature-discovery-gc-5477c88f99-dltjp 1/1 Running 0 24h pod/node-feature-discovery-master-665757d679-g8kt9 1/1 Running 0 24h pod/node-feature-discovery-worker-vv28z 1/1 Running 0 24h pod/node-feature-discovery-worker-zlb5s 1/1 Running 0 24h NAME READY UP-TO-DATE AVAILABLE AGE deployment.apps/node-feature-discovery-gc 1/1 1 1 24h deployment.apps/node-feature-discovery-master 1/1 1 1 24h
Verify the labels on the nodes:
kubectl get nodes -o json | jq '.items[].metadata.labels'
