Kubernetes Service 没有活动 Endpoint

我创建了一个Deployment, Service and an Ingress。不幸的是，ingress-nginx-controllerpod 抱怨我的Service没有活动端点：

controller.go:920] Service "<namespace>/web-server" does not have any active Endpoint.

My Service定义：

apiVersion: v1
kind: Service
metadata:
  annotations:
    prometheus.io/should_be_scraped: "false"
  creationTimestamp: "2021-06-22T07:07:18Z"

My Deployment定义：

在同一个命名空间中，我有更多Service and Deployment资源，所有这些都有效，除了这个（+另一个，见下文）。

# kubectl get endpoints -n <namespace>

如您所见，选择器/标签是相同的（web-server） 在里面Service以及在Deployment定义。

C-Nan https://stackoverflow.com/users/13524500/c-nan已经解决了问题，并发布了解决方案作为评论：

我发现了这个问题。 Pod 已启动，但由于 readinessProbe 失败而未处于 Ready 状态。我不知道在 Pod 处于就绪状态之前不会创建端点。删除 readinessProbe 创建了 Endpoint。
