尽管已创建入口资源，但未创建GCE LoadBalancer

Question

我正在GKE上安装官方jenkins头盔图表。

我正在启用Inrit，因此应该应用相应的模板并创建资源。

根据官方GKE留档：

创建入口时，GKE入口控制器根据入口和相关服务中的信息创建并配置HTTP（S）负载平衡器。此外，负载平衡器有一个稳定的IP地址，您可以将其与域名关联。

然而，我的情况并非如此；入口没有与之关联的外部IP：

▶ k get ingress --all-namespaces
NAMESPACE   NAME                HOSTS   ADDRESS   PORTS   AGE
jenkins     jenkins-inception   *                 80      82s

以下是实际的入口资源：

▶ k get ingress --all-namespaces -o yaml
apiVersion: v1
items:
- apiVersion: extensions/v1beta1
  kind: Ingress
  metadata:
    annotations:
      kubernetes.io/ingress.class: nginx
    creationTimestamp: "2020-01-24T21:20:49Z"
    generation: 1
    labels:
      app.kubernetes.io/component: jenkins-master
      app.kubernetes.io/instance: jenkins-inception
      app.kubernetes.io/managed-by: Tiller
      app.kubernetes.io/name: jenkins
      helm.sh/chart: jenkins-1.9.16
    name: jenkins-inception
    namespace: jenkins
    resourceVersion: "15741661"
    selfLink: /apis/extensions/v1beta1/namespaces/jenkins/ingresses/jenkins-inception
    uid: 6461793e-3eef-11ea-a0a5-42010a790807
  spec:
    rules:
    - http:
        paths:
        - backend:
            serviceName: jenkins-inception
            servicePort: 8080
          path: /jenkins
  status:
    loadBalancer: {}
kind: List
metadata:
  resourceVersion: ""
  selfLink: ""

那是为什么呢？

在kubernetes中尝试了nginx和gce。io/入口。类注释值。

edit_1：似乎HTTP负载平衡Add On已启用。

然而，最奇怪的是：

▶ k describe ingress jenkins-inception -n jenkins
Error from server (NotFound): the server could not find the requested resource

~                                                                                                                                         
▶ k get ingress jenkins-inception -n jenkins
NAME                HOSTS   ADDRESS   PORTS   AGE
jenkins-inception   *                 80      11h

edit_3：解决kubectl兼容性问题后，发现入口没有生成任何事件

▶ k describe ingress jenkins-inception -n jenkins
Name:             jenkins-inception
Namespace:        jenkins
Address:
Default backend:  default-http-backend:80 (10.8.32.33:8080)
Rules:
  Host  Path  Backends
  ----  ----  --------
  *
        /jenkins   jenkins-inception:8080 (10.8.33.87:8080)
Annotations:
  kubernetes.io/ingress.class:  nginx
Events:                         <none>

是否有命令行列出集群上已启用的加载项？

edit_4：关于附加组件...

▶ gcloud container clusters describe inception-cluster --zone us-east4-b | grep -i add -A 6
addonsConfig:
  horizontalPodAutoscaling: {}
  httpLoadBalancing: {}
  kubernetesDashboard:
    disabled: true
  networkPolicyConfig:
    disabled: true

edit_5：在使用@Arghya Sadhu的评论中指出的正确注释启用实际GCE入口后，我在入口描述中看到以下错误

评估入口规范时出现警告Translate 2s（x11 over 7s）loadbalancer控制器错误：服务“jenkins/jenkins inception”类型为“ClusterIP”，应为“NodePort”或“loadbalancer”

然而，这与jenkins官方的以下建议相矛盾：

  # For minikube, set this to NodePort, elsewhere use LoadBalancer
  # Use ClusterIP if your setup includes ingress controller

edit\u 6：管理以获取公共IP的入口：

  spec:
    rules:
    - http:
        paths:
        - backend:
            serviceName: jenkins-inception
            servicePort: 8080
          path: /jenkins
  status:
    loadBalancer:
      ingress:
      - ip: 12.234.543.111

但是我无法访问以下路径：

https://12.234.543.111/jenkins
http://12.234.543.111/jenkins
https://12.234.543.111
http://12.234.543.111

Answer 1

在入口上运行描述。如果您看到创建/添加事件，则表示您在集群中运行了一个入口控制器，否则，您可能在GKE集群上禁用了HttpLoad平衡（GKE入口控制器）附加组件

编辑1：

您在kubernetes服务器和kubectl之间存在版本不兼容。您可以通过运行下面的命令来检查客户端和服务器版本。有关详细信息，请检查此问题。

kubectl version

编辑2：

您不应该有注释kubernetes。io/入口。课程，或者如果你有，它需要是gce的kubernetes。io/入口。类别：gce

编辑3：

根据谷歌云文档，jenkins-inception服务的服务类型需要是NodePort类型
