NFD-GC (NFD Garbage-Collector) is preferably run as a Kubernetes deployment
|
||
|
|
with one replica. It makes sure that all
|
||
|
|
[NodeFeature](custom-resources.md#nodefeature) and
|
||
|
|
[NodeResourceTopology](custom-resources.md#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](../deployment/helm.md#garbage-collector-parameters))
|
||
|
|
NFD-GC will only be deployed when `enableNodeFeatureApi` or
|
||
|
|
`topologyUpdater.enable` is set to true.
