Azure Kubernetes 保持事件 TCP 套接字

Question

我想要连接一个打开 TCP 连接的移动设备到我的一个 kubernetes 服务。问题是在心跳间隔10分钟之前连接就被杀死了。

下面是我的部署

apiVersion: apps/v1
kind: Deployment
metadata:
  name: device-gateway
  labels:
    app: device-gateway
spec:
  replicas: 1
  strategy:
    rollingUpdate:
      maxUnavailable: 0
  selector:
    matchLabels:
      app: device-gateway
  template:
    metadata:
      labels:
        app: device-gateway
    spec:
      containers:
      - name: device-gateway
        image: [IMAGE]
        imagePullPolicy: Always
      imagePullSecrets:
      - name: myregistrykey
---
apiVersion: v1
kind: Service
metadata:
  name: device-gateway
spec:
  type: ClusterIP
  ports:
  - name: my-device-port
    port: 8485
    protocol: TCP
  selector:
    app: device-gateway

我尝试在 Ingress 中设置以下注释

nginx.ingress.kubernetes.io/proxy-socket-keepalive: "on"
nginx.ingress.kubernetes.io/proxy-send-timeout: "1800s"
nginx.ingress.kubernetes.io/proxy-stream-timeout: "1800s"
nginx.org/proxy-send-timeout: "1800s"

service.beta.kubernetes.io/azure-load-balancer-tcp-idle-timeout: "30"

此外，公共(public)IP中的“空闲超时”设置为30分钟。 LoadBalancer 规则也是如此。

我像这样安装了入口 Controller :

helm install nginx-ingress ingress-nginx/ingress-nginx \
    --set tcp.8485="default/device-gateway:8485" \
    --set [more irrelevant settings here]

我猜这与配置有关，那么如何将超时设置为 30 分钟？

我已经发布了社区 wiki 答案来总结该主题。

OP 找到了解决方法。他在评论中提到了这一点:

I did not find the solution to the problem, but I did remove the problem by send a heartbeat the other way every 5 minutes to keep the line open.

我找到了关于Configure TCP reset and idle timeout for Azure Load Balancer的文章。它可以帮助set tcp reset and idle timeout来自Azure portal .
