containerd common project repository

This project repository contains the governance definitions and specified project roles like maintainers and security advisors.

Scripts and utilities

Originally, this repository held common CI scripts/checks as well as the release-tool. Neither of those items are maintained in this repository. See the below paragraphs for their new locations:

The release-tool utility

The release-tool now has its own repository. It is located in the release-tool subproject.

Common CI checks/scripts

After migrating the entire project and all sub-projects to GitHub Actions for CI, we made a subproject repo that contains a common project-checks action with our file header, DCO, and vendor checks. That repository is located in project-checks

Project core documents

Project governance, maintainer list, and contributing guidelines are all maintained as single copies within this repository and linked to from all containerd projects to reduce duplication and maintenance across all repos.

You can see each of these core documents here:

• Governance for containerd projects
• Maintainers and reviewers list
• Contributing guidelines

For an example of how to include these in a project's README.md file see the following markdown:

## Project details

{Some-project} is a containerd sub-project, licensed under the [Apache 2.0 license](./LICENSE).
As a containerd sub-project, you will find the:
 * [Project governance](https://github.com/containerd/project/blob/main/GOVERNANCE.md),
 * [Maintainers](https://github.com/containerd/project/blob/main/MAINTAINERS),
 * and [Contributing guidelines](https://github.com/containerd/project/blob/main/CONTRIBUTING.md)

Non-core project documents

If your project is a non-core addition to the containerd GitHub organization, please make the following changes to your project once approved and added:

• Clearly state in an opening sentence within your project README.md that "Project X is a non-core subproject of containerd"
• Add the project details boilerplate provided above with the following two changes:
  1. The first line should be modified to state: {Some-project} is a non-core containerd subproject
  2. Do not link to the core MAINTAINERS file in containerd/project. That link should be modified to point to your existing non-core project MAINTAINERS file.
