OpenStack Interop Working Group Process 2021A

Status

Approved #June 29, 2021 OIF board meeting

Replaces

2017A

This document describes the Interop Working Group's working process as required by the OpenStack bylaws (see https://www.openstack.org/legal/bylaws-of-the-openstack-foundation/) and approved by the OpenStack Technical Committee and Open Infrastructure Foundation Board.

Expected Time line

Time Frame Activities Lead By
-1 month Draft of next guidelines. Interop WG
PTG Review next guidelines Community
PTG Review status Interop WG
+1 month Update draft of guidelines Interop WG
+2 months Testing draft guidelines Refstack, Vendors
+3 months Approve Guidance approval_committee

Note: Time line is aligned with releases schedules. See https://releases.openstack.org/xena/schedule.html as example of Xena schedule. Draft is done during the release for which guideline is being developed, while its completion is done during next release schedule. The Interop Working Group may accelerate the process to correct errors and omissions.

Process Definition

The Guideline process has four primary phases: Draft, Review, Validation and Approval. - During the Draft phase (A), the Interop Working Group creates new draft of guideline with input from the community with updated coverage, scores of the components, and other details. - During the Review phase (B), guidelines for each project are reviewed during the PTG with that project, input from refstack community, and general feedback from the community and vendors. - During the Validation phase (C) Guidelines go through and implementation and testing cycle. - Finally, Approval by approval_committee

The Open Infrastructure Board of Directors is not involved in the guideline process and review, and approve only changes to the Interop WG process.

This section provides specific rules and structure for each phase.

Guidelines Draft Phase (A)

Starting: S-1

A1. New Guidelines Start From Previous Guidelines

  1. New Guidelines start from the previously approved Guidelines document.
  2. New Guidelines are given the preliminary name of "next.json".
  3. For each of the new Guidelines add-on component there is a separate "next.json" document.

A2. Community Groups Tests for Capabilities

  1. The Interop Working Group coordinates community activities with the Technical Leadership to revise the capabilities based on current technical needs and functionality.
  2. Capabilities must be a subset of the OpenStack Technical Committee Approved Release as determined by the Board of Directors (see bylaws of the Foundation, section 4.1(b)(iii)).
  3. Groupings may change between iterations.
  4. Tests must have unique identifiers that are durable across releases and changes in grouping.
  5. Tests must be under OpenStack Technical Committee governance.
  6. The Interop Working Group will provide the test groupings in JSON format for scoring.
  7. The Interop Working Group optionally will provide a human-readable summary of the Guideline generated from the JSON version.

A3. Interop Working Group Collects Recommendations for Designated Sections

  1. Designated Sections will not be removed without being deprecated in the previous Guideline.
  2. Designated Sections will not be added without being advisory in the previous Guideline.
  3. Designated Sections will not be added or be made advisory unless the corresponding code base is a subset of the OpenStack Technical Committee Approved Release as determined by the Board of Directors (see bylaws of the Foundation, section 4.1(b)(iii)).
  4. TC & PTLs may, but is not required to, assist the Interop Working Group with defining advisory Designated Sections for projects that have advisory or required Capabilities.
  5. Designated Sections may be sufficiently defined for Guidelines using general descriptions.
  6. The Interop Working Group will present A3.4 descriptions to approval_committee for approval.
  7. TC & PTLs may, but is not required to, provide more specific details describing the Designated Sections for a project.
  8. Designated Sections will be included in the JSON Guideline.

A4. Interop Working Group identifies required capabilities

  1. The Interop Working Group uses Board approved scoring criteria scoring criteria to evaluate Capabilities.
  2. The Interop Working Group needs Board approval to change scoring criteria.
  3. Scoring criteria factors or weights cannot change after Draft is published.
  4. The Interop Working Group identifies a cut-off score for determining that a Capability is required.
  5. Capabilities will not be removed without being deprecated in the previous Guideline.
  6. Capabilities will not be added without being advisory in the previous Guideline.
  7. For the "widely deployed" adoption criteria, the size of the pool being considered will match the scope of the community being considered. Capabilities will be evaluated based on their use in their Component. Components will be evaluated based on their use in the Platform.

A5. The Interop Working Group recommends OpenStack Components and OpenStack Platform Scope

  1. The Interop Working Group recommends Capabilities to include in each OpenStack Component.
  2. The Interop Working Group recommends which Components are required for the OpenStack Powered Platform.
  3. The Interop Working Group will apply the approved scoring criteria to evaluate if a component should be included in the Platform (see A4).

A6. Additional Capabilities and Tests

  1. The Interop Working Group will work with the OpenStack community to define new Capabilities.
  2. Test grouping for new Capabilities will be included in the Interop Working Group documents.
  3. The Interop Working Group will publish a list of missing Capabilities and Capabilities with inadequate test coverage.
  4. Interop Working Group in conjuction with TC and Foundation Marketplace product owner can propose additional Add-on component guidelines.
  5. Each Add-on is provided as a seperate additional guideline, that follows the same process as "OpenStack powered" ones as defined by this document.

Tests must be available in repositories under OpenStack TC governance. The tests cannot be in repositories outside of list in the openstack governance repository: https://opendev.org/openstack/governance/src/branch/master/reference/projects.yaml
  3. Project meeting covers any test result for specific drivers of that project to ensure consistent functionality coverage for all required and designated interoperability functionality of the project.
