如何为istio Ingress网关添加自定义端口? [英] How to add custom port for istio ingress gateway?

问题描述

我是istio的新手.我有一个简单的入口网关yaml文件，侦听端口为26931，但是在应用yaml之后，端口26931不会出现在入口网关公开的端口集中.那么我是否缺少一些必要的步骤或其他内容?

I'm new to istio. I have a simple ingress gateway yaml file, and the listenling port is 26931, but after I applied the yaml, the port 26931 does not appear in the set of ports which ingress gateway expose. So am I lack of some necessary step or something else?

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: batman-gateway
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 26931
      name: http
      protocol: HTTP
    hosts:
    - "*"

推荐答案

您不是通过Gateway对象而是通过istio-ingressgateway服务公开端口.

You are exposing ports not with Gateway object, but with istio-ingressgateway service.

kubectl edit svc istio-ingressgateway -n istio-system

因此，如果要公开端口26931，则应使用网关服务

So if you want to expose port 26931, you should do it with gateway service

  ports:
  - name: http
    nodePort: 30001
    port: 26931
    protocol: TCP
    targetPort: 80
