K8S：错误运行负载均衡器同步例程

Question

正在尝试在 google 云上获取 ThingsBoard 运行。

我现在看到以下错误：

Error during sync: error running load balancer syncing routine: loadbalancer thingsboard-tb-ingress--013d7ab9087175d7 does not exist: CreateUrlMap: googleapi: Error 400: Invalid value for field 'resource': '{ "name": "k8s-um-thingsboard-tb-ingress--013d7ab9087175d7", "hostRule": [{ "host": ["*"], "...'. Invalid path pattern, invalid

kubectl describe ingress 给我以下信息：

我在这里错过了什么？

Answer 1

我忘记指定 kubernetes.io/ingress.class: "nginx" 注释。如果您未指定任何 kubernetes。io/ingress.class - GKE 将考虑使用其自己的入口，该入口不支持正则表达式并给出上述错误。

Answer 2

使用默认的gke loadbalancer和使用错误的路径表达式时出现错误。从文档中： https://cloud.google.com/kubernetes-engine/docs/how-to/load-balance-ingress

Ingress 的路径字段唯一支持的通配符是 * 字符。 * 字符必须跟在正斜杠 (/) 之后，并且必须是模式中的最后一个字符。例如，/、/foo/ 和 /foo/bar/* 是有效模式，但是 、/foo/bar 和/foo/*/bar 不是。
更具体的模式优先于不太具体的模式。如果你同时拥有 /foo/* 和 /foo/bar/，那么 /foo/bar/bat 被用来匹配 /foo/bar/。有关路径限制和模式匹配的详细信息，请参阅 URL 地图文档。

您本身不需要设置主机条目，这个错误实际上非常混乱和不清楚。

来自同一页面，这是一个有效的配置：

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  annotations:
    # If the class annotation is not specified it defaults to "gce".
    kubernetes.io/ingress.class: "gce"
spec:
  rules:
  - http:
      paths:
      - path: /*
        backend:
          serviceName: hello-world
          servicePort: 60000
      - path: /kube
        backend:
          serviceName: hello-kubernetes
          servicePort: 80

要使用正则表达式，您需要使用另一个入口控制器，例如 nginx 或 haproxy：
