Gardener

Universal Kubernetes at Scale

🌱 Welcome to the Gardener Project on GitHub

Gardener Logo

👋 Welcome to the official GitHub organization of the Gardener Project. We are an open-source project that brings homogeneous Kubernetes-clusters-as-a-Service to multi-cloud environments. Our mission is to provide robust, scalable, and efficient Kubernetes clusters using hosted control planes.

🌐 What is Gardener?

Gardener is a Kubernetes extension that implements automated system management. It provides a lean, extensible, and multi-cloud capable API server that integrates existing cloud providers and open-source cloud computing libraries. Gardener is designed to support scalability and resilience for large-scale systems, and it's capable of managing thousands of Kubernetes clusters across multiple cloud providers (AWS, GCP, Azure, OpenStack, AliCloud, and more).

📌 Gardener and NeoNephos

Gardener has been donated to the NeoNephos Foundation, a Linux Foundation initiative dedicated to advancing open-source projects that align with the strategic objectives of Important Project of Common European Interest - Next Generation Cloud Infrastructures and Services (IPCEI-CIS) under neutral governance. Learn more about NeoNephos and our role within it here.

🤝 Gardener and ApeiroRA

ApeiroRA is a reference blueprint for an open, flexible, secure, and compliant next-generation cloud-edge continuum - and therefore a key contribution to IPCEI-CIS. At a high level, the projects of ApeiroRA allow users to provider-agnostically fetch, request and consume services, and for service providers to describe, offer and provision their services. By being open source, ApeiroRA provides a cross-border spillover effect, solidifying the foundation and future of the project. Learn more about ApeiroRA by checking out the official website.

🌟 Key Features

  • Multi-Cloud: Gardener supports a wide range of cloud providers, allowing you to deploy and manage Kubernetes clusters across different cloud environments.
  • Automated Operations: Gardener automates many of the day-to-day tasks involved in managing Kubernetes clusters, such as updates, backups, and scaling.
  • Extensibility: Gardener is designed to be extensible, allowing you to add support for new infrastructure providers, operating systems, networking plugins, and more.
  • Secure and Compliant: Gardener ensures that the Kubernetes clusters are secure and compliant with the necessary standards.
  • Conformance: All Kubernetes clusters managed by Gardener are conformant as per the CNCF's conformance tests.
  • Open-Source: Gardener is completely open-source. We welcome contributions from the community and believe in the power of collaborative development.

👥 Get Involved

We welcome contributions of all kinds, from code to documentation, testing, and design. If you're interested in getting involved, check out our contribution guidelines and our open issues.
