我正在使用两个运行Graphql引擎的服务建立一个Istio服务网格。我打算将它们设置在两个不同的子路径上。您将如何在VirtualService上设置重定向?

我已经尝试使用此VirtualService配置

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: hasura-1
spec:
  hosts:
  - "*"
  gateways:
  - hasura-gateway
  http:
  - match:
    - uri:
        prefix: /hasura1
    route:
    - destination:
        host: hasura-1
        port:
          number: 80
  - match:
    - uri:
        prefix: /hasura2
    route:
    - destination:
        host: hasura-2
        port:
          number: 80

但是,每当尝试访问这些前缀时,我始终会遇到错误404。

编辑:我已经更新了我的虚拟服务,以合并 rewrite.uri 。每当我尝试访问任何一个前缀时,我都将重定向到/,并发出错误404。这是我更新的网关和VirtualService list 。
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: hasura-gateway
spec:
  selector:
    istio: ingressgateway # use istio default controller
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - "*"
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: hasura-1
spec:
  hosts:
  - "*"
  gateways:
  - hasura-gateway
  http:
  - match:
    - uri:
        exact: /hasura1
    rewrite:
      uri: /
    route:
    - destination:
        host: hasura-1
        port:
          number: 80
  - match:
    - uri:
        exact: /hasura2
    rewrite:
      uri: /
    route:
    - destination:
        host: hasura-2
        port:
          number: 80

最佳答案

您的Hasura的GraphQL端点在什么路径上配置?

配置VirtualService的方式,对网关的请求将如下所示:
my.host.com/hasura1-> hasura-1/hasura1my.host.com/hasura1/anotherpath-> hasura-1/hasura1/anotherpathmy.host.com/hasura2-> hasura-2/hasura2
也许您缺少rewrite.uri规则来删除请求中的路径。

例如:使用此规则:

http:
- match:
  - uri:
      prefix: /hasura1
  rewrite:
    uri: /
  route:
  - destination:
      host: hasura-1
      port:
        number: 80

您的Hasura容器应在根路径上收到请求:
my.host.com/hasura1-> hasura-1/my.host.com/hasura1/anotherpath-> hasura-1/anotherpath
