Kubernetes Component Operator Runtime

About this project

A framework to support development of Kubernetes operators managing Kubernetes components.

The operators implemented through this framework are strongly opiniated in the sense that instances of the managed component are described through a dedicated, specific custom resource type.

The key features are:

Efficient and smart handling of Kubernetes API extensions (custom resource definitions or API aggregation).
Ability to fully take over rendering of the component's resources by implementing
```
  type Generator interface {
      Generate(ctx context.context, namespace string, name string, parameters types.Unstructurable) ([]client.Object, error)
  }
```
(where parameters correspond to the spec of the describing custom resource component object).
Projects having existing Helm charts or Kustomizations describing the component's lifecylce can reuse these by bundling them into the component operator, leveraging the included ready-to-use HelmGenerator resp. KustomizeGenerator implementations.
Scaffolding tool to bootstrap new component operators in minutes, see the Getting Started documentation.
