Allow self-service management of Role Bindings

Profile Applicability: L2

Type: Behavioral

Category: Self-Service Operations

Description: Tenants should be able to perform self-service operations by creating their rolebindings in their namespaces.

Rationale: Enables self-service management of roles.

Audit:

As cluster admin, create a tenant

kubectl create -f - <<EOF
apiVersion: capsule.clastix.io/v1beta1
kind: Tenant
metadata:
  name: oil
spec:
  owners:
  - kind: User
    name: alice
EOF

./create-user.sh alice oil

As tenant owner, run the following command to create a namespace in the given tenant

kubectl --kubeconfig alice create ns oil-production
kubectl --kubeconfig alice config set-context --current --namespace oil-production

As tenant owner check for permissions to manage rolebindings for each verb

kubectl --kubeconfig alice auth can-i get rolebindings
kubectl --kubeconfig alice auth can-i create rolebindings
kubectl --kubeconfig alice auth can-i update rolebindings
kubectl --kubeconfig alice auth can-i patch rolebindings
kubectl --kubeconfig alice auth can-i delete rolebindings
kubectl --kubeconfig alice auth can-i deletecollection rolebindings

Each command must return 'yes'

Cleanup: As cluster admin, delete all the created resources

kubectl --kubeconfig cluster-admin delete tenant oil
