K8S：运行负载平衡器同步例程时出错

Question

试图让ThingsBoard在谷歌云上运行。

我现在看到以下错误：

同步期间出错：运行负载均衡器同步例程时出错：loadbalancer thingsboard-tb-ingress--013d7ab9087175d7 不存在：CreateUrlMap：googleapi：错误 400：字段“资源”的无效值：“{“名称”：“k8s-um- Thingsboard-tb-ingress--013d7ab9087175d7", "hostRule": [{ "host": ["*"], "...'。路径模式无效，无效

kubectl describe ingress 给了我以下信息：

我在这里缺少什么？

Answer 1

我忘了指定 kubernetes.io/ingress.class: "nginx" 注释。如果您没有指定任何 kubernetes.io/ingress.class - GKE 将考虑使用自己的入口，它不支持正则表达式并给出提到的错误。
