Slurm on Kubernetes with Tenant Isolation
Launch a secure Slurm on Kubernetes service using vCluster's certified stacks. Pre-validated Slurm environments deploy inside fully isolated tenant clusters in minutes.
Trusted by the fastest-growing AI cloud providers
Problem
Why Slurm on Kubernetes Is Hard
Most teams underestimate the complexity of running Slurm on Kubernetes at scale.
Weak Tenant Boundaries
Namespace isolation exposes cluster-wide agents and other tenants' nodes, making Slurm workloads in shared clusters a security liability.
Slow, Expensive Setup
Integrating Slurm with Kubernetes manually requires months of engineering work before a single tenant workload can run.
No Self-Service Experience
AI teams expect cloud-native tooling and self-service environments. A manual provisioning workflow drives them back to hyperscalers.
Solution
Certified Slurm Stacks Inside Isolated Tenant Clusters
vCluster deploys pre-validated Slurm on Kubernetes environments via certified stacks using the Slinky integration. Every tenant gets a fully isolated cluster with its own API server, etcd, and RBAC — so Slurm runs in a secure, dedicated environment without weeks of custom configuration.
Built for Slurm on Kubernetes at Scale
From certified Slurm stacks to kernel-native workload isolation, vCluster delivers every layer needed to run Slurm on Kubernetes securely and at scale.
AI Environments
Certified Slurm on Kubernetes Stacks
Pre-validated Slurm environments via Slinky integration deploy inside tenant clusters in minutes. Skip weeks of manual integration work and go from a bare Kubernetes cluster to a production Slurm environment fast.
- Slinky-based Slurm integration included
- Cluster to AI platform in minutes
- Tested against tenant isolation
Tenant Isolation
Isolated Control Planes Per Tenant
Each tenant running Slurm on Kubernetes gets a dedicated API server, etcd, and scheduler as lightweight pods. Full cluster-admin without shared blast radius or visibility into other tenants' workloads.
- Own API server and etcd per tenant
- Spins up in seconds
- No shared blast radius
Hardware Isolation
Dedicated Nodes for Slurm Workloads
Assign fully dedicated physical nodes to each tenant's Slurm environment with separate CNI and CSI. Eliminates noisy-neighbor GPU contention and significantly reduces the risk of workload performance being impacted by adjacent tenants.
- No cross-tenant workloads on shared nodes
- Own CNI and CSI per tenant
- Full hardware-level separation
Tenant Experience
Self-Service Portal for Slurm Tenants
Tenants provision and manage their own Slurm on Kubernetes environments through an EKS-like self-service portal. Deliver the cloud experience AI teams expect without adding operational burden to your platform team.
- EKS-like self-service experience
- Tenant-controlled environment provisioning
- Reduces platform team overhead
Platform Operations
Fleet Management Across All Clusters
Manage all tenant Slurm clusters from a central UI, CLI, and API. Set quotas, apply templates, enforce SSO, and maintain operational consistency across every tenant environment at scale.
- Central UI, CLI, and API
- Quotas, templates, and SSO built in
- Consistent operations across fleet

FAQs
What is Slurm on Kubernetes and how does vCluster support it?
Slurm on Kubernetes refers to running the Slurm workload manager inside a Kubernetes cluster, typically to manage GPU compute jobs alongside cloud-native workloads. vCluster supports this through certified stacks that include a pre-validated Slinky-based Slurm integration. These stacks deploy inside isolated tenant clusters, meaning each tenant gets a fully functional Slurm environment without sharing control plane resources or node visibility with other tenants.
How does vCluster isolate Slurm environments across multiple tenants?
vCluster runs a dedicated Kubernetes control plane — including its own API server, etcd, and scheduler — for each tenant as lightweight pods inside a host cluster. This gives every Slurm tenant full cluster-admin access and complete isolation from other tenants. For stronger hardware isolation, tenants can be assigned private nodes with separate CNI and CSI, ensuring no cross-tenant workloads run on the same physical servers.
Do I need to build the Slurm on Kubernetes integration myself?
No. vCluster's certified stacks include a pre-validated Slurm environment using the Slinky integration. These stacks are tested and certified to work with vCluster tenant isolation, so you can go from a bare Kubernetes cluster to a production Slurm environment in minutes rather than spending weeks on manual integration work.
Can vCluster run Slurm on Kubernetes on bare metal GPU servers?
Yes. vCluster's full stack includes vMetal for bare metal provisioning and vCluster Standalone, which runs as a binary directly on bare metal without needing k3s, kubeadm, or another base Kubernetes layer. This means you can deploy Slurm on Kubernetes across GPU racks with zero-touch provisioning, from PXE boot through to isolated tenant Slurm environments.
Is the Kubernetes distribution used for Slurm CNCF-certified?
Yes. Every tenant cluster created by vCluster is a CNCF-certified Kubernetes distribution with 100% API compatibility. This means Slurm on Kubernetes environments run on fully conformant clusters, ensuring compatibility with standard Kubernetes tooling, operators, and integrations without any proprietary API dependencies.
How quickly can I launch a Slurm on Kubernetes service for tenants?
vCluster's certified stacks are designed to minimize time-to-production. The pre-validated Slurm environment deploys inside an isolated tenant cluster in minutes. For teams building a managed service, vCluster's platform has enabled GPU cloud providers to launch managed Kubernetes offerings in weeks rather than months, without requiring a large dedicated platform engineering team.
