# Velero Governance
|
|
|
|
This document defines the project governance for Velero.
|
|
|
|
## Overview
|
|
|
|
**Velero**, an open source project, is committed to building an open, inclusive, productive and self-governing open source community focused on building a high quality tool that enables users to safely backup and restore, perform disaster recovery, and migrate Kubernetes cluster resources and persistent volumes. The community is governed by this document with the goal of defining how community should work together to achieve this goal.
|
|
|
|
## Code Repositories
|
|
|
|
The following code repositories are governed by Velero community and maintained under the `vmware-tanzu\Velero` organization.
|
|
|
|
* **[Velero](https://github.com/vmware-tanzu/velero):** Main Velero codebase
|
|
* **[Helm Chart](https://github.com/vmware-tanzu/helm-charts/tree/main/charts/velero):** The Helm chart for the Velero server component
|
|
* **[Velero CSI Plugin](https://github.com/vmware-tanzu/velero-plugin-for-csi):** This repository contains Velero plugins for snapshotting CSI backed PVCs using the CSI beta snapshot APIs
|
|
* **[Velero Plugin for vSphere](https://github.com/vmware-tanzu/velero-plugin-for-vsphere):** This repository contains the Velero Plugin for vSphere. This plugin is a volume snapshotter plugin that provides crash-consistent snapshots of vSphere block volumes and backup of volume data into S3 compatible storage.
|
|
* **[Velero Plugin for AWS](https://github.com/vmware-tanzu/velero-plugin-for-aws):** This repository contains the plugins to support running Velero on AWS, including the object store plugin and the volume snapshotter plugin
|
|
* **[Velero Plugin for GCP](https://github.com/vmware-tanzu/velero-plugin-for-gcp):** This repository contains the plugins to support running Velero on GCP, including the object store plugin and the volume snapshotter plugin
|
|
* **[Velero Plugin for Azure](https://github.com/vmware-tanzu/velero-plugin-for-microsoft-azure):** This repository contains the plugins to support running Velero on Azure, including the object store plugin and the volume snapshotter plugin
|
|
* **[Velero Plugin Example](https://github.com/vmware-tanzu/velero-plugin-example):** This repository contains example plugins for Velero
|
|
|
|
|
|
## Community Roles
|
|
|
|
* **Users:** Members that engage with the Velero community via any medium (Slack, GitHub, mailing lists, etc.).
|
|
* **Contributors:** Regular contributions to projects (documentation, code reviews, responding to issues, participation in proposal discussions, contributing code, etc.).
|
|
* **Maintainers**: The Velero project leaders. They are responsible for the overall health and direction of the project; final reviewers of PRs and responsible for releases. Some Maintainers are responsible for one or more components within a project, acting as technical leads for that component. Maintainers are expected to contribute code and documentation, review PRs including ensuring quality of code, triage issues, proactively fix bugs, and perform maintenance tasks for these components.
|
|
|
|
### Maintainers
|
|
|
|
New maintainers must be nominated by an existing maintainer and must be elected by a supermajority of existing maintainers. Likewise, maintainers can be removed by a supermajority of the existing maintainers or can resign by notifying one of the maintainers.
|
|
|
|
### Supermajority
|
|
|
|
A supermajority is defined as two-thirds of members in the group.
|
|
A supermajority of [Maintainers](#maintainers) is required for certain
|
|
decisions as outlined above. A supermajority vote is equivalent to the number of votes in favor being at least twice the number of votes against. For example, if you have 5 maintainers, a supermajority vote is 4 votes. Voting on decisions can happen on the mailing list, GitHub, Slack, email, or via a voting service, when appropriate. Maintainers can either vote "agree, yes, +1", "disagree, no, -1", or "abstain". A vote passes when supermajority is met. An abstain vote equals not voting at all.
|
|
|
|
### Decision Making
|
|
|
|
Ideally, all project decisions are resolved by consensus. If impossible, any
|
|
maintainer may call a vote. Unless otherwise specified in this document, any
|
|
vote will be decided by a supermajority of maintainers.
|
|
|
|
Votes by maintainers belonging to the same company
|
|
will count as one vote; e.g., 4 maintainers employed by fictional company **Valerium** will
|
|
only have **one** combined vote. If voting members from a given company do not
|
|
agree, the company's vote is determined by a supermajority of voters from that
|
|
company. If no supermajority is achieved, the company is considered to have
|
|
abstained.
|
|
|
|
## Proposal Process
|
|
|
|
One of the most important aspects in any open source community is the concept
|
|
of proposals. Large changes to the codebase and / or new features should be
|
|
preceded by a proposal in our community repo. This process allows for all
|
|
members of the community to weigh in on the concept (including the technical
|
|
details), share their comments and ideas, and offer to help. It also ensures
|
|
that members are not duplicating work or inadvertently stepping on toes by
|
|
making large conflicting changes.
|
|
|
|
The project roadmap is defined by accepted proposals.
|
|
|
|
Proposals should cover the high-level objectives, use cases, and technical
|
|
recommendations on how to implement. In general, the community member(s)
|
|
interested in implementing the proposal should be either deeply engaged in the
|
|
proposal process or be an author of the proposal.
|
|
|
|
The proposal should be documented as a separated markdown file pushed to the root of the
|
|
`design` folder in the [Velero](https://github.com/vmware-tanzu/velero/tree/main/design)
|
|
repository via PR. The name of the file should follow the name pattern `<short
|
|
meaningful words joined by '-'>_design.md`, e.g:
|
|
`restore-hooks-design.md`.
|
|
|
|
Use the [Proposal Template](https://github.com/vmware-tanzu/velero/blob/main/design/_template.md) as a starting point.
|
|
|
|
### Proposal Lifecycle
|
|
|
|
The proposal PR can follow the GitHub lifecycle of the PR to indicate its status:
|
|
|
|
* **Open**: Proposal is created and under review and discussion.
|
|
* **Merged**: Proposal has been reviewed and is accepted (either by consensus or through a vote).
|
|
* **Closed**: Proposal has been reviewed and was rejected (either by consensus or through a vote).
|
|
|
|
## Lazy Consensus
|
|
|
|
To maintain velocity in a project as busy as Velero, the concept of [Lazy
|
|
Consensus](http://en.osswiki.info/concepts/lazy_consensus) is practiced. Ideas
|
|
and / or proposals should be shared by maintainers via
|
|
GitHub with the appropriate maintainer groups (e.g.,
|
|
`@vmware-tanzu/velero-maintainers`) tagged. Out of respect for other contributors,
|
|
major changes should also be accompanied by a ping on Slack or a note on the
|
|
Velero mailing list as appropriate. Author(s) of proposal, Pull Requests,
|
|
issues, etc. will give a time period of no less than five (5) working days for
|
|
comment and remain cognizant of popular observed world holidays.
|
|
|
|
Other maintainers may chime in and request additional time for review, but
|
|
should remain cognizant of blocking progress and abstain from delaying
|
|
progress unless absolutely needed. The expectation is that blocking progress
|
|
is accompanied by a guarantee to review and respond to the relevant action(s)
|
|
(proposals, PRs, issues, etc.) in short order.
|
|
|
|
Lazy Consensus is practiced for all projects in the `Velero` org, including
|
|
the main project repository and the additional repositories.
|
|
|
|
Lazy consensus does _not_ apply to the process of:
|
|
|
|
* Removal of maintainers from Velero
|
|
|
|
## Updating Governance
|
|
|
|
All substantive changes in Governance require a supermajority agreement by all maintainers.
