 *
 *     For build tools which are currently not in the list a custom `dockerImage` can be used with a custom `dockerCommand` as per step [buildExecute](../steps/buildExecute.md)
 *
 * For `buildTool: docker` a local Docker build will be executed in case a Docker deamon is available, if not `buildTool: 'kaniko'` will be used instead.
