ingress-nginx、GCE 和静态 IP

  • 772

所以，我想要一个指向我的 nginx 入口 LB 的静态 IP。

gcloud compute addresses create test-ip --global 
gcloud compute addresses describe test-ip  --global

它为我提供了一个我现在可以使用的静态 IP。

详细输出：

address: 34.120.62.131
addressType: EXTERNAL
creationTimestamp: '2021-02-10T10:27:32.806-08:00'
description: ''
id: '6370409738458995579'
ipVersion: IPV4
kind: compute#address
name: dashboard-ip
networkTier: PREMIUM
status: RESERVED

我正在尝试遵循本指南说明，但“稳定”的 helm repos 已经消失，我尝试使用的 helm 图表如下。我不确定这是否是推荐与 helm 一起使用的，但鉴于它归 K8s 组织所有，这似乎是正确的选择。

帖子中引用的选项不再存在，因此我从图表中获取所有值并覆盖似乎正确的值，尽管我在黑暗中拍摄。

controller:
  service:
    loadBalancerIP: "34.120.62.131"

使用以下方法安装图表：


helm install samir ingress-nginx/ingress-nginx -f override.yml

在这一点上，它陷入了状态。

有什么我想念的吗？

注意：我确实偶然发现了这个替代图表。这似乎更接近我在上面链接的stackoverflow帖子中引用的内容，尽管即使使用它我也无法让它工作。创建集群时我可能错过了一个选项吗？

    我的建议是看一下官方文档，例如，在这里你可以找到如何为你的 nginx-ingress 控制器分配一个静态 IP，你也可以参考这个 GCP 教程，它包含一步一步的指南通过 Helm 安装 Nginx 入口控制器，然后使用外部负载均衡器公开服务，如果您已经保留了 IP，则可以运行以下命令：

    helm install -name [nginx-ingress-name] nginx-stable/nginx-ingress --set controller.service.loadBalancerIP=[YOUR_IP]

    这与您所遵循的指南中的几乎相同，如果您没有事先保留 IP，您只需要让 GKE 分配 IP 并按照教程进行操作，缺少一个步骤是提升外部 IP静态如示例中所述。

    相反，如果您使用 GKE Ingress 控制器，这可以通过在注释“ kubernetes.io/ingress.global-static-ip-name ”中指定静态 IP 的名称来轻松完成，如此处所述，假设您的 IP 是命名为“test-ip”应该是这样的：

    apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  annotations:
    kubernetes.io/ingress.global-static-ip-name: "test-ip"
spec:
...
