Enable providing multiple services with paths in apirules.

[valentinvieriu]

Description

We should have the possibility to have a single hostname and multiple paths mapped to various k8s services. Example:

apiVersion: networking.k8s.io/v1
kind: APIRule
metadata:
  name: coolapp-ingress-wildcard-host
spec:
  rules:
  - host: "coolapp.bar.com"
    http:
      paths:
      - pathType: Prefix
        path: "/api"
        backend:
          service:
            name: customApiService
            port:
              number: 80
      - pathType: Prefix
        path: "/login"
        backend:
          service:
            name: loginService
            port:
              number: 80
      - pathType: Prefix
        path: "/.*"
        backend:
          service:
            name: staticWebsiteService
            port:
              number: 80

Acceptance criteria

• [x] [POC] expose multiple svc under same virtual host](https://github.com/kyma-project/kyma/issues/14421)
• [x] api-gateway implementation
• [x] documentation
• [x] tutorial explaining configuration scenarios
• [x] Kyma Dashboard reflecting changes
• [x] release notes
• [x] automated test

Reasons

For Single Page Applications, this will be a very simple way to consume services, without worrying about CORS overhead and also about how to pass the API endpoints as configurations to the SPA. This is also a good practice that is used by other vendors like Firebase, and Vercel to expose and consume serverless functions to the SPA

Having a similar requirement but for multiple namespaces. Discussion in Slack https://kyma-community.slack.com/archives/CBLBESMST/p1612770790008100

Namespace foo
api.example.com/foo -> service foo

Namespace bar
api.example.com/bar -> service bar

The same domain should be possible to be used in multiple namespaces with different paths to different services. This works for Istio Virtual Services using https://istio.io/latest/docs/reference/config/analysis/ist0109/.

Are there any updates on this issues?

The feature seems quite relevant and multiple scenarios are depending on it. For example the Eclipse Dirigible Web IDE Debugger is not working on Kyma due to CORS issues.

The apirule ability to have a failover service would be a good scenario in this particular issue, but it may be slightly different issue as well. In our setup, we have apirule pointing to a single cache service, but what if cache service is down, I would go directly to service, in case we could configure apirule for that. Thanks, Daniel

[strekm]

@gabel we will handle support for svc from other namespaces in separate ticket. thanks for your input! @dapus123 please open separate feature request for you request. thanks

Is this available in the latest version of kyma?
