A helper operator to block deletion of k8s objects by managing finalizers based on some defined rules
Unfortunately all operators don't take advantage of finalizers. When you delete some CRs, they stop working for
some other CRs. You need to ensure that you don't delete CRs who have some dependents. This operator allows you to
define those dependencies via some rules so that you can block deletion of necessary CRs until some
conditions met.
The helm chart requires rules. The chart creates a configmap on which the operator is mounted and also the chart
creates necessary RBACs for the operator.
rules:
- query: '{{ eq .dependent.spec.template.spec.bootstrap.configRef.name .managed.metadata.name }}'
managed:
group: bootstrap.cluster.x-k8s.io
version: v1beta1
kind: KubeadmConfigTemplate
resource: kubeadmconfigtemplates
dependent:
group: cluster.x-k8s.io
version: v1beta1
kind: MachineSet
resource: machinesets
