This section contains the following reference topics about nodes:

* the kubelet's [sync loop](/docs/reference/node/kubelet-sync-loop/)

* the kubelet's [checkpoint API](/docs/reference/node/kubelet-checkpoint-api/)
* the kubelet's [Pod Info gRPC API](/docs/reference/node/kubelet-pod-info-grpc-api/)
* a list of [Articles on dockershim Removal and on Using CRI-compatible Runtimes](/docs/reference/node/topics-on-dockershim-and-cri-compatible-runtimes/)

* [Kubelet Device Manager API Versions](/docs/reference/node/device-plugin-api-versions)

* [Node Labels Populated By The Kubelet](/docs/reference/node/node-labels)

* [Local Files And Paths Used By The Kubelet](/docs/reference/node/kubelet-files)

* [Node `.status` information](/docs/reference/node/node-status/)

* [Linux Node Swap Behaviors](/docs/reference/node/swap-behavior/)

* [Seccomp information](/docs/reference/node/seccomp/)

* [What happens after a node restart](/docs/reference/node/what-happens-on-restart/)

You can also read node reference details from elsewhere in the
Kubernetes documentation, including:
