Project-infra is a collection of infrastructure-as-code tools and automation utilities that support the KubeVirt project's continuous integration and deployment operations.
The repository addresses the operational needs of a large open-source project by providing a suite of specialized tools for managing CI/CD infrastructure, test quality monitoring, and release processes. It bundles Ansible playbooks for deploying and configuring Prow components, custom Prow plugins, container image definitions, and Go-based automation tools. The approach is modular, with each tool or infrastructure component organized in its own directory and documented with individual READMEs where appropriate.
This project is relevant for teams running Kubernetes-based CI infrastructure at scale, particularly those using Prow for GitHub-integrated testing. It suits organizations that need to automate dependency updates across multiple repositories, track test flakiness across their test suite, manage release workflows, and control resource consumption in cloud environments. The tools address specific operational pain points: flakefinder and flake-stats provide visibility into test reliability, the kubevirtci-bumper automates provider updates, the release-tool streamlines versioning, and the limiter controls cloud costs by managing external connections based on billing alerts.
The project maintains steady activity with regular updates across its multiple components. Development shows consistent attention to automation tooling, with ongoing refinement of CI job management and test quality infrastructure. The codebase reflects pragmatic engineering focused on solving concrete operational problems rather than building generalized frameworks. Contributions are actively reviewed and integrated, with clear documentation provided for adding new features to the infrastructure.
