Why Gardener?

Enterprise-Grade Kubernetes, Zero Operational Overhead

Gardener is an open-source Kubernetes management platform trusted by enterprises worldwide. Deploy clusters via YAML or our intuitive dashboard at dashboard.gardener.leaf.cloud. Focus on your applications while we handle cluster lifecycle, updates, and infrastructure.

Technical Specifications

Production-Ready Kubernetes Infrastructure

Latest Kubernetes

Kubernetes 1.32 (stable) and 1.33 (preview) available. Stay current with upstream releases and easy upgrade paths.

Management Tools

Web dashboard at dashboard.gardener.leaf.cloud or gardenctl CLI for YAML-based infrastructure-as-code workflows.

Fully managed control plane by Leafcloud. Worker nodes deployed in your OpenStack project for full visibility and control.

Advanced Features

Auto-scaling, auto-healing, and cluster hibernation built-in. All Kubernetes resources visible in your OpenStack dashboard.

How It Works

Managed Control Plane, Your Infrastructure

Leafcloud manages the Kubernetes control plane (zero operational overhead), while worker nodes run in your OpenStack project (full visibility and control). Networking and security groups are configured in your project. All cluster resources appear in your OpenStack dashboard for complete transparency.

Carbon Reducing

Calculate Your Yearly Emissions Reduction

Our compute heavy machines are housed in apartment complexes and care homes. That means your workload reduces emissions for heating shower water by replacing natural gas use. With the heat from your workload people get a hot shower! Find out by how much you can reduce emissions

Gardener Features

Everything You Need for Production Kubernetes

YAML Config

Configure your Gardener-managed Kubernetes clusters using simple YAML files. Because life is complicated enough without having to remember XML syntax.

Hibernation

Like a bear in winter, your clusters can take a nap when not needed. Save resources while Gardener keeps everything ready for when Monday morning inevitably arrives.

Auto-Healing

Your clusters heal themselves faster than you can say "is it down?" Gardener keeps everything running while you enjoy your hard earned snack.

Multi Cluster, Multi Cloud

Manage multiple clusters across different clouds as easily as riding a bike. Though unlike Dutch cyclists, Gardener actually stops at red lights.

GPU Support

Deploy GPU-enabled clusters for AI workloads without breaking a sweat. Let Gardener handle the complexity while you figure out what AI actually means.

Latest Updates

Stay current with the latest features, because running outdated Kubernetes is like still using Windows 95. Even your neighbor's printer has a more updated system.

Transparent Pricing

€84.50 per month per cluster, plus compute resources (VMs, GPUs). No hidden fees, no vendor lock-in. Hibernate clusters when not in use to save costs. Full pricing transparency guaranteed.

Frequently Asked Questions

Gardener has its own command-line tool called gardenctl. You can use gardenctl to connect to your cluster and manage your garden.

  • Install Gardenctl: Follow the installation instructions provided in the Leafcloud documentation.
  • Connect to Your Cluster: Use gardenctl commands to access and manage your Kubernetes cluster efficiently. For detailed steps, refer to the Leafcloud Gardenctl Documentation.

You can manage and create Kubernetes clusters (shoots) using Gardener in two main ways:

  • Declaratively with YAML:
    • Define cluster configurations in YAML files.
    • Use gardenctl to apply these configurations, creating or updating clusters as specified.
  • Via the Gardener UI:
    • Access the Gardener dashboard at dashboard.gardener.leaf.cloud.
    • Use the intuitive interface to manage and create clusters. Both methods offer flexible and efficient cluster management. For detailed instructions, visit the Leafcloud Gardenctl Documentation.

The Kubernetes setup consists of several parts:

  • Control Plane: Managed by Leafcloud, it oversees the Kubernetes cluster.
  • Worker Nodes: Created in the customer's OpenStack project to run applications and workloads.
  • Networking: Configured in the customer's OpenStack project to connect worker nodes and resources.
  • Security Groups: Enhance security and control network access in the customer's OpenStack project.

The upgrade process includes:

  • Node Replacement: Nodes are replaced one by one when changing the Kubernetes version.
  • Workload Migration: Workloads from old nodes are automatically migrated to the new nodes.
  • Seamless Transition: Ensures minimal downtime, maintaining consistency and smooth operation.

When you create a LoadBalancer service in Kubernetes:

  • A load balancer is automatically provisioned for you in OpenStack.
  • An external IP is assigned to the load balancer.
  • This load balancer directs traffic from the external IP to your application pods.

When you create a PVC in Kubernetes, a storage volume is automatically created for you in OpenStack based on the specified storage class.

Our Gardener Managed Kubernetes service is available here. For self-managed Kubernetes on OpenStack, see this guide.

You can find documentation related to Leafcloud Kubernetes here.

Leafcloud supports both Calico and Cilium network types.

Leafcloud is committed to staying close to the latest stable Kubernetes release. Currently, we offer Kubernetes version 1.32 (stable) and a preview of version 1.33.
