Custom Operator (don't know anything)
Controller Runtime: The Kubernetes controller-runtime Project is a set of go libraries for building Controllers Operator SDK: The Operator SDK is a framework that uses the controller-runtime library to make writing operators easierhttps://sdk.operatorframework.io/docs/building-operators/ansible/tutorial/

https://two-oes.medium.com/building-custom-ansible-based-operator-for-openshift-4-ec681fa0466d
Example:
operator-sdk init --domain operator.redhatgov.io --plugins ansible
operator-sdk create api --group workshops --version v1alpha1 --kind Workshop --generate-role
It will create some directory structure(defaults file will be available)
Creating CRD:
kubectl create -f config/crd/bases/workshops.operator.redhatgov.io_workshops.yaml
Run custom Operator:
command: make deploy
create custom resource now
-----
apiVersion: workshops.operator.redhatgov.io/v1alpha1
#workshops.operator.redhatgov.io/v1alpha1
kind: Workshop
metadata:
name: example-workshop
spec:
# Add fields here
cr_my_replicas: 1
kubectl create -f config/crd/bases/workshops_v1_workshop_cr.yaml
you can check logs of custom - operator
kubectl logs -f workshop-controller-manager-9f6ff675b-rbcqw -n workshop-system
In RBAC role.yaml
