Fleet controls: Operators can apply shared guardrails across clusters and control available Kubernetes and operating system versions and their lifecycle.gardener.cloud · 3 Oct 2026
Security: Gardener mandates the DISA Security Technical Implementation Guide for Kubernetes and provides adopters a compliance checker for demonstrating DISA Kubernetes STIG compliance.gardener.cloud · 3 Oct 2026
Regional controls: Gardener supports regional placement restrictions, but users are responsible for configuring them to meet applicable regional requirements.gardener.cloud · 3 Oct 2026
Extensibility: Gardener's extension architecture supports external controllers for vendor-specific functionality.gardener.cloud · 3 Oct 2026
Support: The project invites feedback and contributions through GitHub issues and Slack.gardener.cloud · 3 Oct 2026
Who uses it: The adopter page identifies SAP BTP as using Gardener to deploy and manage Kubernetes clusters uniformly across infrastructures.gardener.cloud · 3 Oct 2026
