✨ Generate role binding based on generated role #839

Generate RoleBinding or ClusterRoleBinding based on the generated roles.

In kubebuilder.role_binding.go#L44, it initilized the rolebinding as a static template which only contains ClusterRoleBinding. So we need to edit it manually and it's not auto-updated if you add Role instead of ClusterRole.

fix #760

(BTW, in kubebuilder.role_binding.go#L44, there are several labels generated in template. To keep consistent with other resources, do we need to add it for role/role_binding as well?
(One solution is using kustomize#LabelTransformer or kustomize#patches, which only changes the yaml templates

Hi @Anddd7. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hi, I just got into the issue you refer to in this PR. Is the kustomize namespace replacement considered here? If I manually generate a role like this in my case, the namespace would be replaced with the one set in the main kustomization.yaml file.

This 'controller-tools' is mainly used to parse the annotations of kubebuilder and generate the manifest, no kustomization.

Ref the kubebuilder, it do have kustomization, https://github.com/kubernetes-sigs/kubebuilder/blob/master/pkg/plugins/common/kustomize/v2/scaffolds/internal/templates/config/rbac/kustomization.go.

If we want to overwrite the namespace, i prefer to use an additional config of https://kubectl.docs.kubernetes.io/references/kustomize/builtins/#_namespacetransformer.

Are you stating that you would change how the namespace is set by the projects consuming controller-runtime (kube-builder, operator-sdk, ...) as a follow-up that uses something like unsetOnly: true and setRoleBindingSubjects: allServiceAccounts?
