helm-based project layout

The operator-sdk CLI can generate, or scaffold, a number of packages and files for each Operator project.

helm-based project layout

helm-based Operator projects generated using the operator-sdk init --plugins helm command contain the following directories and files:

File/folders Purpose

File/folders	Purpose
`config`	Kustomize manifests for deploying the Operator on a Kubernetes cluster.
