operator-sdk
SDK for building Kubernetes applications. Provides high level APIs, useful abstractions, and project scaffolding.
Sample implementations of the Kubebuilder project can be found in the sample-controller-kubebuilder and in kubebuilder-sample-controller repositories.
Scaffolding includes many files and manifests. The main.go file, for instance, is the entrypoint of code. It imports the controller-runtime library, instantiates and runs a special manager that keeps track of the controller run. Nothing to change in any of these files.
A controller can be written in any language. We’ll use Golang as Kubernetes’ "native" language. We could write a controller’s logic from scratch but the good folks from Google and RedHat gave us a leg up. They have created two projects that can generate the operator code that will only require minimum changes – kubebuilder and operator-sdk. These two are compared at the kubebuilder vs operator-sdk page, as well as here: What is the difference between kubebuilder and operator-sdk #1758.
