Kubernetes operators without the infrastructure.
Reconciliation as a runtime service.
Security as a runtime service.
Intent Delivery as a runtime service.
Every Kubernetes operator carries three kinds of infrastructure no one wanted to build:
- Reconciliation infrastructure — informers, workqueues, worker pools, leader election, retries, backoff, finalizers, status patching, panic recovery
- Security infrastructure — admission webhooks, validation rules, mutation rules, RBAC generation, TLS management
- Intent delivery infrastructure — CR construction, caller interfaces, field routing, value translation, schema evolution
None of this is the reason the operator exists. All of it is the cost of entry.
Orkestra absorbs all three. You declare behavior — or keep your existing Reconcile function — and the runtime handles the rest.
Two lines. Your Reconcile method is completely untouched.
func NewWebAppReconciler(kube kubeclient.Interface) domain.Reconciler {
return domain.ReconcilerFrom(&WebAppReconciler{
Client: kubeclient.ToClient(kube),
})
}Remove SetupWithManager, Scheme, and main.go. Orkestra provides the informer, workqueue, worker pool, leader election, panic recovery, metrics, retries, health endpoints, and admission webhooks. Or run ork migrate to have the constructor injected automatically:
ork migrate ./controller/webapp_controller.go -o ./my-operator→ Migration Guide · ork migrate reference
No Go required. Declare what the operator should do:
apiVersion: orkestra.orkspace.io/v1
kind: Katalog
metadata:
name: website-operator
spec:
crds:
website:
crdFile: ./crd.yaml
crFiles: [./cr.yaml]
operatorBox:
onCreate:
deployments:
- name: "{{ .metadata.name }}"
image: "{{ .spec.image }}"
replicas: "{{ .spec.replicas }}"
reconcile: true
services:
- name: "{{ .metadata.name }}-svc"
port: 80
targetPort: "{{ .spec.port }}"
reconcile: trueork runOrkestra reads the Katalog, installs the CRD, starts the operator, creates the Deployment and Service, sets owner references, writes status, emits events, corrects drift, and exposes health, metrics, and a control center.
Not a single line of Go.
Every CRD declared in a Katalog becomes a complete, isolated operator. Nothing to configure.
| Informer | Watches your exact GVK. In-memory cache. Zero API calls on read. |
| Workqueue | Per-CRD. Rate-limited. Deduplicated. Isolated from every other CRD. |
| Worker pool | Configurable concurrency. A panic in one CRD does not affect any other. |
| Drift correction | reconcile: true — desired state is enforced on every cycle. |
| Owner references | Child resources deleted when the CR is deleted. No onDelete logic needed. |
| Finalizers | CRs protected from dirty deletion automatically. |
| Events | Every reconcile is a traceable Kubernetes event. |
| Leader election | One active instance. Followers hold warm caches. Failover in under 15s. |
| Status | Ready condition + your own status fields written after every reconcile. |
| Health API | /katalog/{crd}/health, /katalog/{crd}/cr, /metrics — per CRD. |
| Prometheus metrics | Reconcile totals, queue depth, error rate — labeled by GVK. |
| Admission webhooks | Validation and mutation declared in the Katalog. No webhook server to write or deploy. |
| RBAC | ork generate rbac derives ClusterRoles from the Katalog. No manual authoring. |
| Deletion protection | Orkestra and everything it manages cannot be accidentally kubectl delete. |
| Control Center | Realtime visibility per CRD, per Katalog, across instances. Auto-generated operator docs — overview, reconcile mode, child resources, kubectl reference, access control. |
| Developer portal | serve.enabled: true on any CRD surfaces a self-service form in the Control Center. Callers submit intent in their vocabulary — no kubectl, no YAML, no Kubernetes knowledge required. |

Six Runtimes. 75 CRDs. One Control Center.
Live deployment: cc.orkestra.sh
| Traditional (75 operators) | Orkestra | |
|---|---|---|
| Processes | 75 | 6 runtimes + 1 control center |
| Memory | 3.75 GB – 15 GB | ~79 MB per runtime (measured) |
| CRDs under management | 75 | 75 |
| First operator | 3–6 weeks | Under 1 hour |
| Lines of Go | 400+ per operator | 0 |
| Adding a new CRD | Days to weeks | Minutes |
79 MB is a live measurement from a 10-CRD runtime (process_resident_memory_bytes from the /metrics endpoint — raw scrape). The reduction works because Orkestra pays the cost of client-go, leader election, and health servers once per runtime. Per-CRD cost is a goroutine pool and an in-memory cache — the same isolation model as kube-controller-manager. A panic in one CRD is caught by safeReconcile; the others keep running.
Not an operator framework — an operator runtime. A framework gives you libraries and conventions. Orkestra gives you a runtime: the reconciliation loop, security layer, and delivery surface are the runtime's job. You write the behavior.
Not a replacement for Go. Hooks and constructors exist for exactly this reason. ~90% of operators are declarative; ~10% need code. Orkestra handles the 90% and gives the 10% a clean seam — the same informer, queue, health, and metrics infrastructure, with a single function to implement.
Not GitOps. Katalogs define long-lived API contracts resolved at startup. Treat Katalog changes like any other runtime change — deploy through a pipeline.
Not a product — a primitive layer. Notes, autoscaler, serve mode, Katalogs — none of these are products. They are primitives ready for composition.
