Nginx Ingress - 无法写入事件

Question

我正在 GKE 上创建一个 nginx 入口。

在每次重新加载事件时，我的控制器都会打印到日志：

I1019 13:23:31.679126 6 controller.go:145] "Configuration changes detected, backend reload required" I1019 13:23:31.776558
6 controller.go:162] "Backend successfully reloaded" I1019 13:23:31.776897 6 event.go:282] Event(v1.ObjectReference{Kind:"Pod", Namespace:"ingress-development", Name:"ingress-nginx-controller-6d55d6b5cd-g2rqh", UID:"109bb50d-b842-4e78-a9a4-ae3d4fc10166", APIVersion:"v1", ResourceVersion:"347936024", FieldPath:""}): type: 'Normal' reason: 'RELOAD' NGINX reload triggered due to a change in configuration E1019 13:23:31.777294 6 event.go:273] Unable to write event: 'can't patch an event with namespace 'ingress-development' in namespace 'development'' (may retry after sleeping)

我的控制器配置：

我该如何解决这个问题？

Answer 1

我能够重现您的场景，但使用 Helm。

在一个集群中创建 2 个 Nginx Ingress 的原始复制步骤

创建两个 namespaces 用于开发：dev1、dev2 和两个用于 ingress：ing1、ing2.

$ kubectl create ns dev1
$ kubectl create ns dev2
$ kubectl create ns ing1
$ kubectl create ns ing2

下载 Nginx Ingress Controller repo 到本地环境。

$ git clone https://github.com/kubernetes/ingress-nginx

输入带有图表的路径。

$ cd /home/user/ingress-nginx/charts/ingress-nginx

部署第一个Nginx Ingress Controller

helm install ing1 . --set controller.ingressClass=ing1 --set controller.scope.enabled=true --set controller.scope.namespace=dev1 -n ing1

部署第二个Nginx Ingress Controller

helm install ing2 . --set controller.ingressClass=ing2 --set controller.scope.enabled=true --set controller.scope.namespace=dev2 -n ing2

两个 Ingress 都将成功创建，但会出现特定条目：

I1021 16:07:31.719665       6 controller.go:173] "Initial sync, sleeping for 1 second"
E1021 16:07:31.719920       6 event.go:273] Unable to write event: 'can't create an event with namespace 'ing1' in namespace 'dev1'' (may retry after sleeping)
I1021 16:07:31.719951       6 event.go:282] Event(v1.ObjectReference{Kind:"Pod", Namespace:"ing1", Name:"ing1-ingress-nginx-controller-7dcb46fb9c-p7qg8", UID:"38823c84-c7f3-4209-XXXX-3951398fb48d", APIVersion:"v1", ResourceVersion:"111729", FieldPath:""}): type: 'Normal' reason: 'RELOAD' NGINX reload triggered due to a change in configuration
E1021 16:07:35.835493       6 event.go:273] Unable to write event: 'can't create an event with namespace 'ing1' in namespace 'dev1'' (may retry after sleeping)
E1021 16:07:45.835793       6 event.go:273] Unable to write event: 'can't create an event with namespace 'ing1' in namespace 'dev1'' (may retry after sleeping)

但是，如果您在将要监视的 Namespace 中创建 Nginx Ingress Controller，则不会出现此问题。

在新集群中只创建了 2 个 namespaces：dev1 和 dev2。

$ kubectl create ns dev1
$ kubectl create ns dev2

部署两个 nginx ingress controller（与上一个方法相同，将 repo 下载到本地机器等）：

$ helm install dev1 . --set controller.ingressClass=dev1 --set controller.scope.enabled=true --set controller.scope.namespace=dev1 -n dev1

$ helm install dev2 . --set controller.ingressClass=dev2 --set controller.scope.enabled=true --set controller.scope.namespace=dev2 -n dev2

日志输出：

I1021 16:24:16.207839       6 controller.go:173] "Initial sync, sleeping for 1 second"
I1021 16:24:16.208050       6 event.go:282] Event(v1.ObjectReference{Kind:"Pod", Namespace:"dev1", Name:"dev1-ingress-nginx-controller-8444854ff4-8bdfm", UID:"e3168581-f6e7-43f5-b655-2aae07b980a2", APIVersion:"v1", ResourceVersion:"8689", FieldPath:""}): type: 'Normal' reason: 'RELOAD' NGINX reload triggered due to a change in configuration
$

此外，根据 Multiple Nginx Ingress Controllers 文档，如果要在一个集群中运行更多 Ingress controllers，则必须指定 --ingress-class。

Deploying multiple Ingress controllers, of different types (e.g., ingress-nginx & gce), and not specifying a class annotation will result in both or all controllers fighting to satisfy the Ingress, and all of them racing to update Ingress status field in confusing ways.

When running multiple ingress-nginx controllers, it will only process an unset class annotation if one of the controllers uses the default --ingress-class value (see IsValid method in internal/ingress/annotations/class/main.go), otherwise the class annotation become required.

If --ingress-class is set to the default value of nginx, the controller will monitor Ingresses with no class annotation and Ingresses with annotation class set to nginx. Use a non-default value for --ingress-class, to ensure that the controller only satisfied the specific class of Ingresses.

简而言之，将 Nginx Ingress controller 部署在将要监视的同一 Namespace 中不会显示此条目。但是，即使出现此特定条目 Nginx Ingress 也按预期工作。

您是否在 Nginx Ingress 工作中遇到任何问题，或者只是想删除此条目？
