# SIG Node Charter
This charter adheres to the conventions described in the [Kubernetes Charter README] and uses
the Roles and Organization Management outlined in [sig-governance].
## Scope
SIG Node is responsible for the components that support the controlled
interactions between pods and host resources. We manage the lifecycle of pods
that are scheduled to a node. We focus on enabling a broad set of workload
types, including workloads with hardware specific or performance sensitive requirements. We maintain
isolation boundaries between pods on a node, as well as the pod and the host. We
aim to continuously improve node reliability.
### In scope
SIG [readme]
#### Code, Binaries and Services
- 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)
#### Cross-cutting and Externally Facing Processes
- CRI [validation] and [testing policy]
- Node [test grid] and [perf dashboard]
### Out of scope
- network management ([sig-network](../sig-network))
- persistent storage management ([sig-storage](../sig-storage))
## Roles and Organization Management
This sig adheres to the Roles and Organization Management outlined in [sig-governance]
and opts-in to updates and modifications to [sig-governance].
### Additional responsibilities of Chairs
- Technical leads seeded by legacy SIG chairs from existing subproject owners
### Additional responsibilities of Tech Leads
None
### Deviations from [sig-governance]
None
