+**imageRepositoryOverride**:
+
+Alternative repository for the Docker image for the microservice.
+Optional.  If this value is set, the Docker image for the microservice
+will be pulled from the repository specified by this value, instead of
+from the repository set by ``repositoryGenerator.repository``.  Note that
+this alternative repository is used only for the microservice image and
+not for other images (such as images for initContainers).  Note also that
+the alternative repository must not use any form of authentication,
+because there is no way to provide credentials for the repository.
