## Goals

The following topics fall under scope of this SIG.

- Kubelet and its features
- Pod API and Pod behaviors (with [sig-architecture](../sig-architecture))
- Node API (with [sig-architecture](../sig-architecture))
- Node controller
- Node level performance and scalability (with [sig-scalability](../sig-scalability))
- Node reliability (problem detection and remediation)
- Node lifecycle management (with [sig-cluster-lifecycle](../sig-cluster-lifecycle))
- Container runtimes
- Device management
- Image management
- Node-level resource management (with [sig-scheduling](../sig-scheduling))
- Hardware discovery
- Issues related to node, pod, container monitoring (with [sig-instrumentation](../sig-instrumentation))
- Node level security and Pod isolation (with [sig-auth](../sig-auth))
- Host OS and/or kernel interactions (to a limited extent)

We also work closely with [sig-storage](../sig-storage) and [sig-network](../sig-network). As you can see, this is a very cross-functional team!
