我正在设置一个 Istio 服务网格,其中包含两个运行 Graphql 引擎的服务。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?

我已经尝试过使用这个 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

但是每当我尝试访问这些前缀时,我都会遇到错误 404。

编辑:我已经更新了我的虚拟服务以合并rewrite.uri. 每当我尝试访问任一前缀时,我都会被重定向到/并给出错误 404。这是我更新的网关和 VirtualService 清单。

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:
    - "*"

Hasura 的 GraphQL 端点配置在什么路径上?

按照您VirtualService的配置方式,对网关的请求将如下所示:

my.host.com/hasura1--> hasura-1/hasura1
my.host.com/hasura1/anotherpath--> hasura-1/hasura1/anotherpath
my.host.com/hasura2-->hasura-2/hasura2

也许您缺少rewrite.uri从请求中删除路径的规则。

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 容器应该接收根路径上的请求:

my.host.com/hasura1--> hasura-1/
my.host.com/hasura1/anotherpath-->hasura-1/anotherpath
