# SIG Autoscaling Charter
2+
3+
This charter adheres to the conventions described in the [Kubernetes Charter README] and uses
4+
the Roles and Organization Management outlined in [sig-governance].
5+
6+
## Scope
7+
8+
Covers development and maintenance of Kubernetes components for automated
9+
scaling in Kubernetes. This includes automated vertical and horizontal
10+
pod autoscaling, initial resource estimation, cluster-proportional system
11+
component autoscaling, and autoscaling of Kubernetes clusters themselves.
12+
13+
### In scope
14+
15+
- Autoscaling-related API objects, such as the HorizontalPodAutoscaler and
16+
VerticalPodAutoscaler
17+
18+
- Autoscaling-related tools, such as the cluster autoscaler,
19+
single-component scaling tools (e.g. pod-nanny), and
20+
cluster-proportional scaling tools
21+
22+
- Ensuring API interfaces (the scale subresource) are available and usable
23+
to enable other SIGs to write autoscalable objects, and enable people to
24+
interact with those interfaces.
25+
26+
[Link to SIG section in sigs.yaml][sigs.yaml]
27+
28+
#### Code, Binaries and Services
29+
30+
- Components and utilities that take automated action to scale a component
31+
on the cluster (e.g. the horizontal-pod-autoscaler or addon-resizer
32+
subproject)
33+
34+
- Components and utilities that take automated action to scale the cluster
35+
itself (e.g. the cluster-autoscaler subproject)
36+
37+
- Special parts of client-go for interacting with with the scaling
38+
interfaces used by the HPA (e.g. the scale-client subproject)
39+
40+
#### Cross-cutting and Externally Facing Processes
41+
42+
- Reviewing implementations of the scale subresource to ensure that
43+
autoscaling behaves properly
44+
45+
- Coordinating with SIG Instrumentation to ensure that metrics APIs are
46+
suitable for autoscaling on.
47+
48+
- Coordinating with SIG Scheduling to make sure scheduling decisions can
49+
interact well with the cluster autoscaler
50+
51+
- Coordinating with SIG Cluster Lifecycle on integration between the
52+
cluster autoscaler and cluster API
53+
54+
- Coordinating with SIG Node around Kubelet requirements for vertical
55+
scaling of pods
56+
57+
### Out of scope
58+
59+
- Testing general cluster performance at scale (this falls under the
60+
purview of [SIG Scalability]).
61+
62+
- Owning metrics APIs (this falls under the purview of [SIG
63+
Instrumentation]). SIG Autoscaling should collaborate with [SIG
64+
Instrumentation] to ensure that metrics APIs are suitable for using in
65+
autoscaling.
66+
67+
## Roles and Organization Management
68+
69+
This sig follows adheres to the Roles and Organization Management outlined in [sig-governance]
70+
and opts-in to updates and modifications to [sig-governance].
71+
72+
### Deviations from [sig-governance]
73+
74+
- SIG Autoscaling does not have chairs as a separate entity from tech
75+
leads. The tech leads have the responsibility of chairs.
76+
