Kubernetes Ingress不适用于traefisk

Kubernetes Ingress不适用于traefisk,kubernetes,kubernetes-ingress,Kubernetes,Kubernetes Ingress,我在谷歌云平台上创建了一个kubernetes集群，之后，我在集群上安装了Helm/tiller，之后，我用Helm安装了traefik，就像官方文档所说的那样现在我尝试为服务创建入口，但是如果我放置注释kubernetes.io/ingres.class:traefik，则入口的负载平衡器不会创建。但是如果没有注释，它可以使用默认入口。（服务类型为nodeport）编辑：我也在一个干净的google云kubernetes集群中尝试了这个例子：但它是一样的，当我选择kubernetes.

kubernetes.io/ingres.class:traefik

，则入口的负载平衡器不会创建。但是如果没有注释，它可以使用默认入口。（服务类型为nodeport）

编辑：我也在一个干净的google云kubernetes集群中尝试了这个例子：但它是一样的，当我选择

kubernetes.io/ingres.class:traefik

时，不会为ingres创建负载平衡器

已创建服务，但未创建入口负载平衡器：

但是，如果我删除行

kubernetes.io/ingres.class:traefik

它与默认的kubernetes入口一起工作

，您可以尝试添加更多注释，如下所示

traefik.ingress.kubernetes.io/frontend-entry-points: http,https
traefik.ingress.kubernetes.io/redirect-entry-point: https
traefik.ingress.kubernetes.io/redirect-permanent: "true"

像这样,

默认情况下，Traefik不会为您创建负载平衡器

如文件所述：

创建入口对象时，GKE入口控制器将创建 Google云平台HTTP（S）负载平衡器及其配置根据入口中的信息及其相关信息服务

这一切都适用于GKE入口控制器（gce）-有关gce的更多信息，您可以在此处找到：

如果您想使用Traefik作为入口，则必须使用

类型：LoadBalancer

例如：

apiVersion: v1
kind: Service
metadata:
  name: traefik
spec:
  type: LoadBalancer
  selector:
    k8s-app: traefik-ingress-lb
  ports:
  - port: 80
    targetPort: 80

更多信息和大量的解释图和实际工作的例子，你可以在文章中找到

希望有此帮助。

这对我不起作用。你能在谷歌云kubernetes中运行这个例子吗？我正在努力，但没有成功。入口的负载平衡器从未创建过服务文件中的类型“NodePort”在哪里？哦，我看到创建了两个服务“NodePort”。如果您想使用LoadBalancer，您可以更改类型：LoadBalancer而不是NodePort。请参考此url了解LoadBalancer，并参考此url了解NodePort+入口：是的，我解决了，使用traefik，您不会为每个入口创建负载平衡器，但使用默认的gce Ingress controller，您可以为每个入口创建不同的负载平衡器，我一开始就不太理解这种差异。现在我只有一个用于traefik“proxy”的负载平衡器，所有其他服务都通过它。这对我不起作用。你能在谷歌云kubernetes中运行这个例子吗？我正在努力，但没有成功。入口的负载平衡器从未创建过服务文件中的类型“NodePort”在哪里？哦，我看到创建了两个服务“NodePort”。如果您想使用LoadBalancer，您可以更改类型：LoadBalancer而不是NodePort。请参考此url了解LoadBalancer，并参考此url了解NodePort+入口：是的，我解决了，使用traefik，您不会为每个入口创建负载平衡器，但使用默认的gce Ingress controller，您可以为每个入口创建不同的负载平衡器，我一开始就不太理解这种差异。现在我只有一个用于traefik“proxy”的负载平衡器，所有其他服务都会通过它。为什么您认为kubernetes.io/ingres.class:traefik应该为您创建LoadBalancer？这是kubernetes.io/ingres.class:gce，他为您创建了loadballancer，但不是traefikWow！真正地我读到“当你创建一个Ingress对象时，GKE Ingress controller会创建一个Google云平台HTTP（S）负载平衡器，并根据Ingress及其相关服务中的信息对其进行配置。”这里：然后我想，使用traefik我还需要编写Ingress，负载平衡器将自动创建。。。那么，使用traefik，我应该将服务从NodePort更改为LoadBalancer吗？或者我应该在创建负载平衡器之后使用NodePort创建服务？为什么您认为kubernetes.io/ingres.class:traefik应该为您创建LoadBalancer？这是kubernetes.io/ingres.class:gce，他为您创建了loadballancer，但不是traefikWow！真正地我读到“当你创建一个Ingress对象时，GKE Ingress controller会创建一个Google云平台HTTP（S）负载平衡器，并根据Ingress及其相关服务中的信息对其进行配置。”这里：然后我想，使用traefik我还需要编写Ingress，负载平衡器将自动创建。。。那么，使用traefik，我应该将服务从NodePort更改为LoadBalancer吗？或者我应该在创建负载平衡器之后使用NodePort创建服务？
