Core Features

Managing add-ons, policies, and configurations across multiple Kubernetes clusters is complex and error-prone. Sveltos simplifies this with automated deployments, real-time updates, and consistent policy enforcement

Kubernetes Add-on Management Across Multiple Clusters

  • Centralized management of add-ons across multiple Kubernetes clusters
  • Support for managing both the management cluster and managed clusters
  • Ability to handle tens of clusters simultaneously

Multiple Add-on Format Support

  • Helm charts
  • Raw YAML manifests
  • Kustomize resources
  • Carvel ytt
  • Jsonnet

Profile & ClusterProfile System

  • ClusterProfiles: Apply across all clusters in any namespace (global scope)
  • Profiles: Limited to specific namespaces (tenant scope)
  • Enables multi-tenancy support with clear separation of concerns

How it works

Sveltos automates add-on deployment and drift correction across Kubernetes clusters using GitOps and label-based targeting—ideal for scalable, hands-off multi-cluster ops

In Just 3 Easy Steps!

    1. Step 1: From the management cluster, select one or more clusters with a Kubernetes label selector.
    2. Step 2: List which add-ons need to be deployed on such clusters.
    3. Step 3: As soon as a cluster is a match for above ClusterProfile instance, all referenced features are automatically deployed.

Use Cases

Sveltos is designed to cater to a wide range of use cases, from small teams to large enterprises.

Project Sveltos enables efficient, declarative deployment and management of database instances across Kubernetes clusters in multi-cloud environments. It standardizes database configurations, including storage, replication, and security settings, ensuring compliance and consistency across clusters. With built-in monitoring and self-healing, Sveltos maintains database health and availability, automatically addressing issues to keep services reliable and performant.
Project Sveltos streamlines the deployment and management of Kubernetes add-ons across clusters, enabling centralized control over tools like monitoring, logging, and security. By using a declarative approach aligned with GitOps, Sveltos ensures add-ons are consistently applied, version-controlled, and easily updated across environments. This automation reduces operational overhead, improves reliability, and maintains uniformity in add-on management across diverse cluster deployments.
Project Sveltos simplifies the deployment and management of NATS clusters across Kubernetes environments, enabling consistent, automated configuration for message streaming and data distribution. With Sveltos's declarative approach, NATS configurations—such as scaling, security settings, and versioning—are uniformly applied across clusters, enhancing reliability in distributed systems. Built-in monitoring and self-healing ensure high availability, automatically addressing issues to keep the messaging infrastructure robust and responsive.
Project Sveltos can deploy Kong as an API Gateway in the management cluster, subsequently deploy nginx services to managed clusters, and finally leverage templating and event mechanisms to expose these services through the API Gateway in the management cluster.
