Single Group to Multi-Group

Let’s migrate the CronJob example.

To change the layout of your project to support Multi-Group run the command kubebuilder edit --multigroup=true. Once you switch to a multi-group layout, the new Kinds will be generated in the new layout but additional manual work is needed to move the old API groups to the new layout.

Generally, we use the prefix for the API group as the directory name. We can check api/v1/groupversion_info.go to find that out:

package v1

Then, we’ll rename move our existing APIs into a new subdirectory, “batch”:

mkdir api/batch
mv api/* api/batch

After moving the APIs to a new directory, the same needs to be applied to the controllers. For go/v4:

mkdir internal/controller/batch
mv internal/controller/* internal/controller/batch/
