1. Prepare artifacts for the application, including docker images etc.
2. Run operator-sdk command to create an Ansible type operator.
3. Modify the scaffolding code to build the operator:

• Add the tasks to ansible playbook
• Modify or add CRDs and CRs
• Modify the role and rolebinding
• Build docker image for the operator
• Update Deployment to use the docker image

4. Two approaches to install the operator and deploy application.

• Install manually
  • create serviceaccount
  • create role and rolebinding
  • create the operator deployment
  • deploy the application with customresource
• Install through OLM
  • generate clusterserviceversion
  • update csv and verify with operator-courier
  • build image for operator-registry
  • create catalogsource using the registry image
    • if the sourcenamespace has an operatorgroup watching the targetnamespaces, then the operator can be installed to the targetnamespace
    • otherwise, need to create an operatorgroup
  • create the operator deployment with a subscription
  • deploy the application by creating an instance of the provided API
