Features
Orchestrating deployments across a fleet of clusters
Centralized Distribution
Sveltos is the control plane for your Kubernetes fleet. It manages the distribution of Helm charts, Kustomize overlays, and YAML/JSON manifests from a management cluster to all the managed clusters.
Learn More Orchestrated Deployment Order
Deploy custom resources in a defined order. Ensure deployments are predictable, controlled, and synchronized across every cluster.
Learn More
Drift Detection & Remediation
Automatically detect and correct configuration drift. Ensure clusters always match the desired state, preventing manual 'quick fixes' from causing permanent issues.
Learn More
Powerful Templating
Represent add-ons as templates and let Sveltos automatically inject cluster-specific details for truly dynamic and consistent deployments.
Learn More
Event Framework
Go beyond static deployments with an event-driven architecture. Monitor managed clusters for specific changes and trigger automatic actions or remediations.
Learn More
Scale Your Fleet with Absolute Security and Control
Pull Mode
Enable zero-trust management where agents connect outbound to the management plane. Securely manage clusters without opening inbound ports or exposing API servers.
Progressive Rollouts & Promotions
Minimize blast radius by staging deployments across environments. Promote changes from Dev to Production only after health checks pass, ensuring fleet-wide stability.
Integrated MCP Server
Empower your AI-driven operations. Sveltos provides a native MCP Server, allowing AI SRE tools to securely discover, query, and manage your entire Kubernetes fleet using natural language.
Unified Orchestration in Six Simple Steps
Centralized Control
A single management cluster acts as the 'source of truth,' orchestrating configurations across your entire fleet from a central point.
Define Your Intent
Use ClusterProfiles and Profiles to declaratively define add-ons, Helm charts, and policies as standard Kubernetes CRDs.
Smart Targeting
Automatically match configurations to clusters using label selectors. Sveltos ensures the right resources reach the right environments instantly.
Orchestrate & Sequence
Set deployment phases and resource dependencies to ensure your stack boots in the correct order across every managed cluster.
Automated Syncing
Choose your sync mode: OneTime, Continuous, or ContinuousWithDriftDetection to maintain your desired state without manual intervention.
Real-Time Distribution
Managed clusters receive updates via push or pull modes, with a lightweight agent ensuring the local state matches your global intent.
Tutorials, guides & deep dives
Learn how to get the most out of Sveltos with step-by-step video tutorials and written guides.
The Swiss Army Knife stack for Multi Cluster Kubernetes
Building a platform to manage multi-tenant, multi-cluster Kubernetes environments follows the same philosophy: a modern Kubernetes cluster manager may appear as a unified product, but under the hood, it is the result of carefully assembling multiple technologies, each solving a distinct problem: cluster lifecycle management, control plane orchestration, policy enforcement, and workload configuration across distributed environments. This talk explores my highly opinionated stack based on the must-have building blocks to design and implement such a platform: it's not just a matter of flavour, I'll share the reasoning behind key architectural and technological choices.
