jitli@RedHat:~/work/src/github/sdk/operator-sdk$ ./build/operator-sdk generate bundle -h

Flags:
      --channels string                  A comma-separated list of channels the bundle belongs to (default "alpha")
      --crds-dir string                  Directory to read cluster-ready CustomResoureDefinition manifests from. This option can only be used if --deploy-dir is set
      --default-channel string           The default channel for the bundle
      --deploy-dir string                Directory to read cluster-ready operator manifests from. If --crds-dir is not set, CRDs are ready from this directory. This option is mutually exclusive with --input-dir and piping to stdin
      --extra-service-accounts strings   Names of service accounts, outside of the operator's Deployment account, that have bindings to {Cluster}Roles that should be added to the CSV
  -h, --help                             help for bundle
      --input-dir string                 Directory to read cluster-ready operator manifests from. This option is mutually exclusive with --deploy-dir/--crds-dir and piping to stdin. This option should not be passed an existing bundle directory, as this bundle will not contain the correct set of manifests required to generate a CSV. Use --kustomize-dir to pass a base CSV
      --kustomize-dir string             Directory containing kustomize bases in a "bases" dir and a kustomization.yaml for operator-framework manifests (default "config/manifests")
      --manifests                        Generate bundle manifests
      --metadata                         Generate bundle metadata and Dockerfile
      --output-dir string                Directory to write the bundle to
      --overwrite                        Overwrite the bundle's metadata and Dockerfile if they exist (default true)
+     --overwrite-annotations            Only overwrite annotations.yaml without modifying bundle.Dockerfile
      --package string                   Bundle's package name
  -q, --quiet                            Run in quiet mode
      --stdout                           Write bundle manifest to stdout
      --use-image-digests                Use SHA Digest for images
  -v, --version string                   Semantic version of the operator in the generated bundle. Only set if creating a new bundle or upgrading your operator

Global Flags:
      --plugins strings   plugin keys to be used for this subcommand execution
      --verbose           Enable verbose logging
