Goals

The following topics fall under scope of this SIG.

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

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