weight: 3
---

By the nice opertor framework guys at IBM and RedHat.
I'll skip the baseline introduction of what an operator is.

## Operator DSK

> Build the operator

* Kubebuilder with v4 Plugines -> Supports the latest Kubernetes
* Java Operator SDK is not a part of Operator SDK and they released 5.0.0
  * Now with server side apply in the background
  * Better status updates and finalizer handling
  * Dependent ressource handling (alongside optional dependent ressources)

## Operator Liefecycle Manager

> Manage the operator -> A operator for installing operators

### OLM v1 APIs

* New API Set -> The old CRDs were overwhelming
* More GitOps friendly with per-tenant support
* Prediscribes update paths (maybe upgrade)
* Suport for operator bundels as k8s manifests/helmchart

### OLM v1 Components

* Cluster Extension (User-Facing API)
  * Defines the app you want to install
  * Resolvs requirements through catalogd/depply
* Catalogd (Catalog Server/Operator)
* Depply (Dependency/Contraint solver)
* Applier (Rukoak/kapp compatible)
