resource pathing behind nginix ingress

We’re attempting to run a dotvvm site in Kubernetes behind a Nginx ingress.

while everything works locally, even if run from a docker container, when running behind the ingress we’re seeing issues where the site wont load.

its specifically failing trying to find a ‘dotvvm–internal’ script at the (example) url https://myCoolURLhere.com/dotvvmResource/jUwMRn0laxpYA4BX1REy/dotvvm--internal behind the ingress the path should be https://myCoolURLhere.com/assessments/dotvvmResource/jUwMRn0laxpYA4BX1REy/dotvvm--internal

We were originally also having problems getting bootstrap and our css to load, changing from the following

config.Resources.Register("bootstrap-css", new StylesheetResource() { Location = new UrlResourceLocation("~/Content/bootstrap.min.css") }); to config.Resources.Register("bootstrap-css", new StylesheetResource() { Location = new UrlResourceLocation("./Content/bootstrap.min.css") });

fixes the pathing to bootstrap, and the css files when behind the ingress.

Is there a property or configuration setting I can adjust so that it looks for the dotvvm–internal script with the appropriate ingress path included ?

Thanks.

I was able to get it running with a combination of ingress (without rewriting) and UsePathBase:

ingress.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kubernetesvirtualdirectorytest-ingress
  labels:
    service: kubernetesvirtualdirectorytest
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rules:
  - host: "kubernetesvirtualdirectorytest.local"
    http:
      paths:
      - path: /sub-app
        pathType: Prefix
        backend:
          service:
            name: kubernetesvirtualdirectorytest
            port: 
              number: 80

Startup.cs

...
app.UsePathBase("/sub-app");
app.UseRouting();
...

Are you using rewrite rule on the ingress to remove the /assessments segment? I think this would be the problem - the app needs to know it is running in a virtual directory so it would generate the URLs correctly.

I’m closing this, I assume it worked. Please reopen or open a new issue if the problem persists
