kubernetes - 使用具有多个端口和协议的相同 Istio Gateway

Question

我正在尝试使用两种不同的协议（GRPC 和 HTTP）配置 istio 网关

现在，我有两个不同的网关，分别用于 GRPC 和 HTTP，如下所示

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gwgrpc
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 7878
      name: http
      protocol: GRPC
    hosts:
    - "*"
---
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gwrest
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 7979
      name: http
      protocol: HTTP
    hosts:
    - "*"

是否可以使用具有不同协议和端口的相同网关？

Answer 1

您应该能够组合这两个网关。唯一的问题是您的两个端口具有相同的名称。像这样的东西应该工作。

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: gwgrpc
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 7878
      name: grpc
      protocol: GRPC
    hosts:
    - "*"
  - port:
      number: 7979
      name: http
      protocol: HTTP
    hosts:
    - "*"

Answer 2

您可能希望将此示例用作模板。同意@Frank：您需要更改名称。这是示例配置的一小部分

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: my-gateway
spec:
  selector:
    app: my-gatweway-controller
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - uk.bookinfo.com
    - eu.bookinfo.com
    tls:
      httpsRedirect: true # sends 301 redirect for http requests
  - port:
      number: 443
      name: https
      protocol: HTTPS
    hosts:
    - uk.bookinfo.com
    - eu.bookinfo.com
