KubeBuilder

Use kubebuilder to start a new project:

 

     kubebuilder init --domain my.domain --repo my.domain/guestbook

This step creates make file, dockerfile etc.

Once a project gets created, you normally run the following command to add API

     kubebuilder create api --group webapp --version v1 --kind CronJob 

Then you normally would edit the files in api/v1 _types.go files to add your own struct

basically data structure for your api. and make changes to the controller.go in the

controllers directory to implement your business logic.

Then you normally would need to run:

    make manifests to generate crds, roles, role bindings etc.

    make generate to generate code in zz_generated.deepcopy.go to capture changes that you

make to apis, that is, changes made in _types.go file will need to be reflected in

zz_generated.deepcopy.go file.
