Node feature discovery for Kubernetes
33fdf75190
Enable Custom Resource based label creation in nfd-master. This extends the previously implemented controller stub for watching NodeFeatureRule objects. NFD-master watches NodeFeatureRule objects in the cluster and processes the rules on every incoming labeling request from workers. The functionality relies on the "raw features" (identical to how nfd-worker handles custom rules) submitted by nfd-worker, making it independent of the label source configuration of the worker. This means that the labeling functions as expected even if all sources in the worker are disabled. NOTE: nfd-master is stateless and re-labeling only happens on the reception of SetLabelsRequest from the worker – i.e. on intervals specified by the core.sleepInterval configuration option (or -sleep-interval cmdline flag) of each nfd-worker instance. This means that modification/creation of NodeFeatureRule objects does not automatically update the node labels. Instead, the changes only come visible when workers send their labeling requests. |
