kolla-build错误安装fluent-plugin-rewrite-tag-filter serverengine需要Ruby版本> = 2.1.0

我正在使用kolla / kolla-ansible 5.0.0，我只是build立了所有的容器图像，并把它们推送到我的本地dockerregistry。 有一张图片显示了kolla无法构build的stream畅的图像。 以下是我在fluentd.log中遇到的错误：

你可以从底部看到它抱怨说不能安装fluent-plugin-elasticsearch和fluent-plugin-rewrite-tag-filter。 它说serverengine需要Ruby版本> = 2.1.0。 我怎么能得到它具有ruby2.1，将解决它？ 我真的需要这个容器来build立。
