入口资源停止同步吗？什么事件表明了这一点？

Question

我运行入口控制器，并为round_robin算法运行一个注释。但似乎那里没有任何活动。如果在我的入口描述中没有任何事件的话，可以吗？什么事件表明了这一点？

# kubectl describe ingress -n ingress

Name:             nginx-ingress

Namespace:        ingress

Address:          192.168.10.10,192.168.10.45

Default backend:  default-http-backend:80 (<error: endpoints "default-http-backend" not found>)

Rules:

  Host             Path  Backends

  ----             ----  --------

  website.com  

                   /           website1:80 (10.42.0.139:80,10.42.1.223:80,10.42.2.98:80 + 1 more...)

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

                   /website3   website3:80 (10.42.0.141:80,10.42.1.215:80,10.42.2.58:80 + 1 more...)

Annotations:       nginx.ingress.kubernetes.io/load-balance: round_robin

Events:            <none>

我和这个兄弟一起部署我的入口，我也有我的入侵者阶级。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

再加上一个注释，我就可以在我的入口中得到事件。

Answer 1

这意味着您的集群没有安装入口控制器。当您的集群中安装了入口控制器(如进气口-)时，将触发一系列事件来处理您的入口请求。这些事件将在“描述”命令中显示。

如果您有入口控制器，但没有将其注册为集群的默认入口类，则可以将注释kubernetes.io/ingress.class: <name of your IngressClass, example "nginx">添加到入口规范中，或者：

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

实际上，同步并不总是显示出来的。当我们在一开始进行更改时，入口控制器就会同步。但是，一段时间后，同步将自动停止。
