入口资源停止同步?那里显示了什么事件

Question

我运行ingress控制器，并为要运行的round_robin算法添加一个注释。但那里似乎没有活动。如果我的入口描述中没有事件，可以吗？那里显示了什么事件？

# kubectl describe ingress -n ingress
Name:             nginx-ingress
Namespace:        ingress
Address:          192.168.10.10,192.168.10.45

/website2    website2:80 (10.42.0.140:80,10.42.1.232:80,10.42.2.74:80 + 1 more...)

我用这个兄弟部署我的入口，我有我的入口类。更新1。

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: nginx-ingress
namespace: ingress
annotations:
nginx.ingress.kubernetes.io/load-balance: ewma
spec:
ingressClassName: nginx
rules:
- host: service.com
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: service1
port:
number: 80
- path: /service2
pathType: Prefix
backend:
service:
name: service2
port:
number: 80
- path: /service3
pathType: Prefix
backend:
service:
name: service3
port:
number: 80

通过另一个注释，我在入口中获得了事件

Events:

Answer 1

这意味着您的集群没有安装入口控制器。当集群中安装了ingress控制器(如ingress nginx(时，会触发一系列事件来处理您的ingress请求。这些事件将显示在描述命令中。

如果你有ingress控制器，但它没有注册为集群的默认ingress类，你可以将注释kubernetes.io/ingress.class: <name of your IngressClass, example "nginx">添加到你的ingress规范或：

apiVersion: networking.k8s.io/v1
kind: Ingress
...   
spec:
ingressClassName: <name of your IngressClass, example "nginx">
...

事实上，同步并不总是显示的。当我们在一开始做更改时，入口控制器会同步。但是，一段时间后，同步将自动停止。
