| # SIG Node Governance | ||
| # 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 hardware and performance sensitive workloads. We maintain | ||
| 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 | ||
|
|
||
| The following topics fall under ownership of this SIG. | ||
|
|
||
| * Kubelet related features (e.g. Pod lifecycle) | ||
| * Node level performance and scalability (with [sig-scalability](../sig-scalability)) | ||
| * Node reliability (prooblem detection and remediation) | ||
| * Node lifecycle management (with [sig-cluster-lifecycle](../sig-cluster-lifecycle)) | ||
| * Container runtimes | ||
| * Device management | ||
| * Images, package management | ||
| * Host 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) | ||

|
|
||
| ## Roles | ||
|
|
||
| Membership for roles tracked in: [OWNERS] | ||
|
|
||
| - **Chairs** | ||
| - Run operations and processes governing the SIG | ||
| - *MUST* remain active in the role and are removed from the position if they | ||
| are unresponsive for > 3 months and *MAY* be removed if not proactively | ||
| working with other chairs to fulfill responsibilities. To remove an | ||
| inactive chair, a majority vote from existing chairs should occur. If a | ||
| [super-majority] is not possible, the [steering-committee] may sponsor | ||
| removal. | ||
| - *MAY* declare an intention to take sabbatical for no more than 3 months in a | ||
| calendar year. Chairs should notify existing chairs of their intent, and | ||
| absent at least 2 remaining chairs, *MUST* nominate a temporary replacement | ||
| from the existing set of technical leads during this period. | ||
| - *SHOULD* represent a diverse set of organizations. This is predicated on | ||
| interest in the role from multiple organizations with qualified candidates. | ||
| Qualification is measured by existing chairs and *SHOULD* be supported by a | ||
| majority of SIG Members under [lazy-consensus]. | ||
| - *MAY* decide to step down at any time and propose a replacement. Use lazy | ||
| consensus amongst chairs with fallback on majority vote to accept proposal. | ||
| This *SHOULD* be supported by a majority of SIG Members. | ||
| - *MAY* select additional chairs through a [super-majority] vote amongst | ||
| chairs. This *SHOULD* be supported by a majority of SIG Members. | ||
| - Number: 1-3 | ||
| - Defined in [sigs.yaml] | ||
|
|
||
| - **Technical Leads** | ||
| - Technical leads seeded by legacy SIG chairs from subproject owners | ||
| - Establish new subprojects | ||
| - Decommission existing subprojects | ||
| - Sponsor working groups | ||
| - End of life working groups | ||
| - *MUST* ensure that all areas of the SIG (including those that fall outside | ||
| subprojects) have active owners. | ||
| - *MAY* set SIG milestone priorities. | ||
| - *SHOULD* act as an escalation point for technical disputes in subprojects. | ||
| - *MUST* resolve issues impacting multiple subprojects in the SIG. | ||
| - *SHOULD* meet or communicate regularly enough to ensure they are aligned. | ||
| Decisions made by technical leads should be consistent across the SIG. If | ||
| technical leads are providing inconsistent direction, then they *MUST* align | ||
| themselves. | ||
| - *MAY* select additional tech leads through a [super-majority] vote amongst | ||
| tech leads and chairs. This *SHOULD* be supported by a majority of SIG | ||
| Members under [lazy-consensus]. | ||
| - *SHOULD* represent a diverse set of organizations. This is predicated on | ||
| interest in the role from multiple organizations with qualified candidates. | ||
| - *MUST* remain active in the role and are automatically removed from the | ||
| position if they are unresponsive for > 3 months and *MAY* be removed if not | ||
| proactively working with other technical leads to fulfill responsibilities. | ||
| Removal of a technical lead requires [super-majority] vote amongst tech | ||
| leads and chairs. | ||
| - *MAY* declare an intention to take sabbatical for no more than 3 months in a | ||
| calendar year. Chairs should notify existing chairs of their intent, and | ||
| absent at least 2 remaining chairs, *MUST* nominate a temporary replacement | ||
| from the existing set of technical leads during this period. | ||
| - Technical Leads *SHOULD* represent a diverse set of organizations. This is | ||
| predicated on interest in the role from multiple organizations with | ||
| qualified candidates. | ||
| - *SHOULD* have a record of consistent solid technical judgement and | ||
| leadership over a sustained period especially over areas for which they are | ||
| the de-facto lead | ||
| - Number: 3-7 | ||
| - Defined in [sigs.yaml] and [OWNERS] files | ||
|
|
||
| - **Subproject Owners** | ||
| - Scoped to a subproject defined in [sigs.yaml] | ||
| - Seed subproject owners *MAY* include initial proposal author(s) and/or Tech | ||
| Leads | ||
| - *MUST* be an escalation point for technical decisions and failing or flaky | ||
| tests in the subproject | ||
| - *MUST* proactively maintain the subproject health and status or delegate | ||
| this responsibility. For actively developed projects, this *SHOULD* include | ||
| setting milestone priorities, tracking release bits, and ensure adequate | ||
| test coverage. For maintenance mode projects, this *SHOULD* include | ||
| maintaining test health and ensuring compatibility with new features. | ||
| - *MUST* remain active in the role and are automatically removed from the | ||
| position if they are unresponsive for > 3 months. | ||
| - *MAY* declare an intention to take sabbatical for no more than 3 months in a | ||
| calendar year. Should notify existing owners of their intent, and *MAY* | ||
| nominate a temporary replacement from the existing set of owners during this | ||
| period. | ||
| - *SHOULD* have a record of consistent solid technical judgement over a | ||
| sustained period, especially over areas for which they are the owner | ||
| - *MAY* be removed if not proactively working with other Subproject Owners to | ||
| fulfill responsibilities. | ||
| - *MAY* decide to step down at any time and propose a replacement. Use | ||
| [lazy-consensus] amongst subproject owners with fallback on majority vote to | ||
| accept proposal. This *SHOULD* be supported by a majority of subproject | ||
| contributors (those having some role in the subproject). | ||
| - *MAY* select additional subproject owners through a [super-majority] vote | ||
| amongst subproject owners. This *SHOULD* be supported by a majority of | ||
| subproject contributors (through [lazy-consensus] with fallback on voting). | ||

| - Defined in [sigs.yaml] [OWNERS] files | ||
|
|
||
| - Members | ||

|
||
| ### Project management | ||
|
|
||
| #### Subproject creation | ||
|
|
||
| - Subprojects *MAY* be created by [KEP] proposal and *MUST* be approved by at | ||
| least 1 tech lead, and accepted by [lazy-consensus] with fallback on majority | ||
| vote of SIG Technical Leads. The result *SHOULD* be supported by the majority | ||
| of SIG members. | ||
| - KEP *MUST* establish subproject owners | ||
| - [sigs.yaml] *MUST* be updated to include subproject information and [OWNERS] | ||
| files with subproject owners | ||
| - Where subprojects processes differ from the SIG, they must document how | ||
| - e.g. if subprojects release separately - they must document how release | ||
| and planning is performed | ||
| - Subprojects may not be seeded from existing repositories pending CNCF | ||
| process definition | ||
|
|
||
| ### Technical processes | ||
|
|
||
| Subprojects of the SIG *MUST* use the following processes unless explicitly | ||
| following alternatives they have defined. | ||
|
|
||
| - Proposing and making decisions | ||
| - Proposals *SHOULD* be sent as [KEP] PRs and published to | ||
| [kubernetes-sig-node] as an announcement | ||
| - Proposals *MUST* be presented and discussed in at least 1 SIG node meeting | ||
| - If the authors are unable to attend, another community member can be found | ||
| to champion the proposal. | ||
| - Proposals *SHOULD* follow [KEP] decision making process | ||
| - For proposed extensions to a subproject, the subproject *MUST* be | ||
| identified in the KEP, and approvers *MUST* include subproject owners | ||
|
|
||
| - Test health | ||
| - Canonical health of code published to [testgrid] | ||
| - Consistently broken tests automatically send an alert to | ||
| [kubernetes-sig-node-test-failures] | ||
| - SIG members are responsible for responding to broken tests alert. PRs that | ||
| break tests should be rolled back if not fixed within 1 business day. | ||
| - Test dashboard checked and reviewed at start of each SIG meeting. Owners | ||
| assigned for any broken tests and followed up during the next SIG meeting. | ||
