Could we also add a desired workflow for users to be able to install operators?

| With the help of the following inputs, kapp-controller can then convert the registry+v1 contents into a set of plain kubernetes manifests. |

I think a little bit more details need to be added on how kapp-controller can convert this into plain Kubernetes manifests.

@praveenrewar The conversion between OLM's registryV1 to plain k8s manifest is based on a yaml named "ClusterServiceVersion" - CSV (https://olm.operatorframework.io/docs/concepts/crds/clusterserviceversion/). There is a direct 1 on 1 translation - which means that based on the info given specified in a CSV yaml (like deployment spec and permissions) we create individual ClusterRoles, service accounts, Bindings, Deployments etc.

@praveenrewar The e2e workflow remains the same as it is now with any other bundle using kapp-ctrl with the introduction of this templating step. With this change, we intend to enable the installation of operators using an OLM specific format. That being said, kapp-ctrl as is can still deploy operators - if it is packaged using Helm chart, or just through a bunch of plain k8s manifests. |
