SIG Cluster Lifecycle Charter

Mon, 01 Jan 0001 00:00:00 +0000

Scope

SIG Cluster Lifecycle’s objective is to simplify creation, configuration, upgrade, downgrade, and teardown of Kubernetes clusters and their components.

In scope

The following topics fall under ownership of this SIG:

Improving the Kubernetes user experience for cluster administration.
Tools that assist in the creation, configuration, upgrade, downgrade, and teardown of Kubernetes control plane components.
Portable APIs for provisioning, configuration, upgrade/downgrade, and de-provisioning of nodes.
Tools that assist in management of configuration of Kubernetes components.
The configuration of core add-ons that are required for cluster bootstrapping.

Code, Binaries and Services

Everything that falls in the scope of the SIG.
Tools that are provider specific implementation for infrastructure management.
Core add-ons (e.g. DNS) that are required for cluster bootstrapping.

Cross-cutting and Externally Facing Processes

The SIG recommends and verifies compatibility of critical cluster add-ons for networking, network policy, service discovery, etc. The SIG maintains the health check of container images for some add-ons that are required for cluster bootstrapping. While the SIG could provide support to users that have add-on related issues, the SIG can decide to delegate issues to the add-on maintainers or other SIGs.
The SIG collaborates regularly with SIG Auth in an effort to follow best practices in order to promote secure default clusters.
The SIG co-owns cloud provider specific code related to cluster and machine provisioning with the respective SIGs for each cloud provider but does not own the cloud controller manager or any other provider specific code.
The SIG ensures that the Kubernetes “release informing” and “release blocking” E2E test jobs that it maintains are in good health.

Out of scope

Networking related issues (see sig-network ).
User interface, or user experience, issues other than cluster bootstrapping or management (see sig-ui and sig-cli ).
Node related issues (see sig-node ).
Kubernetes control plane issues:
- Control plane component related issues (see sig-api-machinery and sig-scheduling ).
Deployment and lifecycle issues related to user application deployments (see sig-apps ).

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 .
