What is k8s.io?

The k8s.io repository is the operational backbone for the Kubernetes project's own websites and cloud infrastructure. Instead of building a software application for others to use, it holds all the configuration and code needed to keep the community's online services running smoothly. This includes managing the DNS for kubernetes.io and k8s.io, hosting web-based tools, and keeping the cloud environment organized and secure. At a high level, the project acts as a master blueprint for the community's cloud resources. It contains configurations to run several web-based tools, such as a code search engine, an election platform for community leadership roles, and a dashboard for viewing performance metrics. It also manages Google Groups for email communication and automates the creation of cloud resources using infrastructure-as-code tools like Terraform, which lets the team define their cloud setup declaratively rather than clicking through a web console. The primary users are the volunteer members of the Kubernetes community, specifically those in special interest groups like sig-k8s-infra, sig-testing, and sig-release. For example, the testing team uses this infrastructure to run end-to-end tests, the release team relies on automated bots to publish new versions of the software, and the contributor experience team uses it to manage Slack tooling and community elections. It provides a transparent, shared space where different teams can maintain the tools they rely on daily. The project is notable for its commitment to transparency and open governance. It includes automated policy checks to validate resources before they are deployed, ensuring the infrastructure remains stable and secure. The repository also provides a publicly viewable billing report, openly sharing the cost of running the Kubernetes project's infrastructure with the community. This approach ensures that a massive, globally distributed open-source project can manage its cloud footprint collaboratively and visibly.
