Multiple ShinyProxy Instances With One Default

[ei-ds]

Hi,

first, thanks for this amazing work!

I managed to run a minikube cluster with distinct ShinyProxy instances listening to different endpoints of our domain defined with

spec:
  server:
    servlet:
      context-path: /sp{1..n}

However, I'm struggling to define one default instance, e.g. sp1, listening to the root, i.e. https://shinyproxy-demo.local the others to their respective endpoint, e.g. https://shinyproxy-demo.local/sp2.
I tried to remove the servlet statement from one of the deployment definitions but Skipper responds with 404 - Not found. Please see the Kubernetes config (k8s-config.txt) attached.

Is this scenario possible at all? If so, what should be configured differently?

Edit: Uploaded fixed config file.

Hi

This is not possible with the current implementations. The rules in the Skipper ingress are already fairly complex, so I believe it's not a good idea to further expand these.

What I propose is to use a redirect to the default instance. So if I user goes to https://shinyproxy-demo.local, that they are automatically redirect to https://shinyproxy-demo.local/sp1. (this will not happen if they directly go to https://shinyproxy-demo.local/sp2.
If you are using nginx ingress this can be very easy, for example:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ngingx-to-skipper-ingress
  namespace: kube-system
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/proxy-body-size: 5000m
    nginx.ingress.kubernetes.io/proxy-read-timeout: "180"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "180"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    nginx.ingress.kubernetes.io/app-root: /test1
spec:
  rules:
  - host: operator-demo.local
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: skipper-ingress
            port:
              number: 9999
