Ingress 中的托管证书，域状态为 FailedNotVisible

Question

我只是按照这里的教程：https://cloud.google.com/kubernetes-engine/docs/how-to/managed-certs#creating_an_ingress_with_a_managed_certificate

一切正常，直到我部署我的证书并等待 20 分钟，它显示为：

Status:
  Certificate Name:    daojnfiwlefielwrfn
  Certificate Status:  Provisioning
  Domain Status:
    Domain:  moviedecisionengine.com
    Status:  FailedNotVisible

该域显然有效，所以我缺少什么？

编辑：

这是证书：

    domains:

Answer 1

我成功地将 Managedcertificate 与 GKE Ingress 资源一起使用。

让我详细说明一下：

重现步骤：

• 创建 IP 地址 gcloud
• 更新 DNS 条目
• 创建部署
• 创建服务
• 创建证书
• 创建 Ingress 资源

使用 gcloud 创建 IP 地址

调用以下命令创建静态 ip 地址：

$ gcloud compute addresses create example-address --global

使用以下命令检查新创建的 IP 地址：

$ gcloud compute addresses describe example-address --global

更新 DNS 条目

转到 GCP -> Network Services -> Cloud DNS。

用 A record 使用上面创建的相同地址编辑您的区域。

等待申请。

检查 $ nslookup DOMAIN.NAME 条目是否指向正确的地址。

创建部署

下面是响应流量的示例部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello
spec:
  selector:
    matchLabels:
      app: hello
      version: 1.0.0
  replicas: 3
  template:
    metadata:
      labels:
        app: hello
        version: 1.0.0
    spec:
      containers:
      - name: hello
        image: "gcr.io/google-samples/hello-app:1.0"
        env:
        - name: "PORT"
          value: "50001"

用命令应用它 $ kubectl apply -f FILE_NAME.yaml

您可以更改此部署以适合您的应用程序，但请注意您的应用程序将响应的端口。

创建服务

使用 NodePort，因为它与提供的 link 相同：

apiVersion: v1
kind: Service
metadata:
  name: hello-service
spec:
  type: NodePort
  selector:
    app: hello
    version: 1.0.0
  ports:
  - name: hello-port
    protocol: TCP
    port: 50001
    targetPort: 50001

用命令应用它 $ kubectl apply -f FILE_NAME.yaml

创建证书

如指南所示，您可以使用以下示例创建 ManagedCertificate:

apiVersion: networking.gke.io/v1beta1
kind: ManagedCertificate
metadata:
  name: example-certificate 
spec:
  domains:
    - DOMAIN.NAME

用命令应用它 $ kubectl apply -f FILE_NAME.yaml

The status FAILED_NOT_VISIBLE indicates that certificate provisioning failed for a domain because of a problem with DNS or the load balancing configuration. Make sure that DNS is configured so that the certificate's domain resolves to the IP address of the load balancer. -- Google Cloud documentation

此证书的创建应该会受到您之前提供的 DNS 条目的影响。

创建 Ingress 资源

下面是 Ingress 资源的示例，它将使用 ManagedCertificate:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress
  annotations:
    kubernetes.io/ingress.global-static-ip-name: example-address
    networking.gke.io/managed-certificates: example-certificate
spec:
  rules:
  - host: DOMAIN.NAME
    http:
      paths:
      - path: /
        backend:
          serviceName: hello-service
          servicePort: hello-port

用命令应用它 $ kubectl apply -f FILE_NAME.yaml

它完全工作大约需要 20-25 分钟。
