👋 Welcome to Projectsveltos!

Sveltos is a Kubernetes add-on controller. It deploys and manages add-ons and applications across many clusters using label-based matching. Sveltos does not compete with GitOps controllers like ArgoCD or Flux. Instead, it extends their capabilities. It runs in a management cluster and supports Helm charts, raw YAML/JSON, Kustomize, Carvel ytt, and Jsonnet formats.

Sveltos stands out for:

• Label-based fleet targeting: One configuration serves any matching cluster.
• Flexible drift detection (agent or agentless): Choose the mode that fits your environment.
• Per-cluster templating: Same definition, different values per cluster.
• Event framework and progressive rollouts: Safe, automated, and adaptable.
• Edge Deployments: Lightweight agents built for tight CPU, memory, and bandwidth budgets. Sveltos deploys only what's needed.

"Adding a new cluster with the right labels automatically brings everything to the desired state."

• 🔄 Orchestrated Deployment Order: Deploy resources in a defined order using simple Custom Resource Definitions (CRDs). Predictable, controlled rollouts.
• 👥 Multitenancy: Use ClusterProfile for fleet-wide policies and Profile for namespace-scoped tenant isolation.
• 🧩 Templating: Define add-ons and applications as templates; Sveltos instantiates them per cluster using cluster metadata.
• ⚡ Event-driven Framework: Trigger deployments from in-cluster or NATS events, with matching logic written in Lua or CEL.
• 🛡️ Pull Mode: Deploy into restricted environments: air-gapped, edge, or behind firewalls.
• 🚦 Progressive rollouts: Phased deployments from a single configuration; no need to maintain multiple profiles.
• 📢 Observability: Notifications via Slack, Teams, Discord, Webex, Telegram, SMTP, or Kubernetes events.
