我目前正在使用自托管的Gitlab 11.9实例。我可以将kube群集添加到单个级别的项目中，而不能添加到组级别（11.10中引入的项目）中。
我在AWS EKS上创建了一个Kubernetes集群，并将其成功连接到特定项目的Gitlab的Autodevops。我能够成功安装Helm分er，Prometheus和Gitlab Runner。 Autodevops在该项目上运行良好。
在我发现在Gitlab 11.10中引入了在组级别运行集群之前，我先将kube集群与第一个项目断开连接，然后在组级别进行了连接。我成功安装了Helm Tiller，但未能安装Ingres或Cert-Manager。在发现我的版本不包含组级别的autodevops功能后，我将群集连接到另一个不同的应用程序，并尝试安装Prometheus和Gitlab Runner。但是，操作失败。
我的豆荚如下：
% kubectl get pods --namespace=gitlab-managed-apps
NAME READY STATUS RESTARTS AGE
install-prometheus 0/1 Error 0 18h

这是我的日志文件中的一些输出：

除了服务，容器，专门用于autodevops的部署之外，该集群不包含其他任何内容。我应该如何“重置”集群或卸载服务？
