repositoryName

The name to use for the repository. The repository name may be specified on its own (such as `nginx-web-app`) or it can be prepended with a namespace to group the repository into a category (such as `project-a/nginx-web-app`). If you don't specify a name, CFNlong generates a unique physical ID and uses that ID for the repository name. For more information, see Name type. The repository name must start with a letter and can only contain lowercase letters, numbers, hyphens, underscores, and forward slashes. If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.
