Cloudfleet Kubernetes Engine (CFKE) runs a fully managed, CNCF-conformant control plane and connects it to virtual machines on your own Proxmox VE servers. There is nothing to install or upgrade on your side: Cloudfleet handles the API servers, etcd, certificates, security patches, and Kubernetes version upgrades. Provision nodes with Terraform and cloud-init, and each VM registers itself with your cluster automatically in two to three minutes.
Proxmox VE is a virtualization platform, not a container ecosystem, so it ships no image registry. Cloudfleet Container Registry (CFCR) fills that gap with a fully managed, OCI-compliant registry included with every organization. Store, share, and pull container images without running Harbor or a self-hosted registry next to your cluster, backed by Cloudfleet's highly available platform.
No managed databases behind your firewall? Deploy production-ready operators and Helm charts straight onto your Proxmox-backed clusters through Cloudfleet Charts Marketplace (preview). PostgreSQL, MongoDB, Redis, observability tools, ingress controllers, and more, all pre-configured. You keep full control of your infrastructure while getting the convenience of managed services.
Proxmox VE gives you a powerful, open-source foundation for running virtual machines on your own hardware, and adoption has surged as teams move away from VMware after the Broadcom acquisition and its licensing changes. But Proxmox does not orchestrate containers. Getting to production Kubernetes still means standing up and maintaining k3s, kubeadm, or Talos yourself, and owning every upgrade, patch, and control plane failure.
Cloudfleet removes that work. It delivers a fully managed Kubernetes control plane and turns your Proxmox VMs into cluster nodes that provision, join, and heal automatically. Your data and workloads stay on your hardware, while the operational complexity moves to Cloudfleet. When you need more capacity than your data center can provide, add nodes from AWS, GCP, Azure, or Hetzner to the same cluster and burst into the cloud without re-architecting anything.
Skip self-managed Kubernetes on Proxmox with k3s, kubeadm, or Talos. Cloudfleet runs and operates the control plane for you, including API servers, the persistence layer, security patches, and zero-downtime version upgrades. If your team knows Kubernetes, you can run production clusters on Proxmox in minutes, not weeks.
Add Proxmox VMs to your cluster with the Cloudfleet Terraform provider and cloud-init. Clone a template, apply, and each VM installs the node components and registers with your cluster on boot. Scaling up is a single variable change, and nodes join in two to three minutes with no manual bootstrapping.
Keep steady-state workloads on your cost-effective Proxmox hardware and expand into AWS, GCP, Azure, Hetzner, and more when demand spikes. A single Cloudfleet cluster spans on-premises and cloud through an encrypted overlay network, so you handle peaks without over-provisioning your data center.
Workloads and data run on servers you own and control, with no hyperscaler lock-in and no CLOUD Act exposure. Cloudfleet is European-headquartered, and nodes only need outbound HTTPS to reach the control plane, so nothing is exposed to the public internet.
Cloudfleet renders a cloud-init join file for the node. You upload it to the Proxmox snippets store, and Proxmox injects it into the VM on boot. The node then installs Kubernetes components and registers with your cluster automatically.
Use standard Kubernetes labels to schedule sensitive or stateful workloads onto your on-premises Proxmox nodes, while letting other pods burst into the cloud.

Proxmox VE delivers enterprise virtualization on your own hardware at a fraction of proprietary licensing costs. Cloudfleet adds the missing layer: a hyperscaler-grade managed Kubernetes experience on top of it, so you get cloud-native operations without giving up control of your infrastructure.
Proxmox VE is fully open source with no per-socket licensing, and Cloudfleet runs certified upstream Kubernetes. Your stack stays portable and standards-based from the hypervisor up.
Teams migrating from vSphere to Proxmox after Broadcom’s licensing changes get a managed Kubernetes story on day one, without trading one vendor lock-in for another.
Combine Proxmox nodes with public cloud instances in one cluster. Run baseline load on-premises for cost and control, and scale into the cloud on demand, all from a single Kubernetes API.
Fine-grained role-based access control (RBAC) with organization and project scopes, least-privilege permissions, and comprehensive audit trails for all user actions.
Enterprise Single Sign-On (SSO) via SAML and OIDC, integrating with Okta, Microsoft Entra ID, Google Workspace, and other compatible identity providers.
Governance, centralized audit logging, and compliance readiness aligned with SOC 2 and ISO 27001 standards (certifications in progress).
Built to support large-scale, mission-critical deployments with dedicated teams, proven processes, and clear operational commitments.
Expert-led architecture, deployment, and migration services to help you design, roll out, and scale Cloudfleet across complex environments.
A dedicated customer success team guiding onboarding, adoption, and long-term success, with access to best practices and operational guidance.
24/7 access to experienced engineers via defined support channels, with clear escalation paths for critical incidents.
Clearly defined Service Level Agreements (SLAs) covering availability, response times, and incident handling for mission-critical workloads.
