resource pathing behind nginix ingress about dotvvm HOT 5 CLOSED

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.

It seems that DotVVM doesn't know that the URL rewriting in Ingress is happening.

Can you try calling UsePathBase and specify the "/assessments" so DotVVM will know on which "real" URL it is running?

Thank you for the response,

I tried what you suggested and set the path base when running behind the ingress.
i also made sure that UsePathBase is being applied before the call to app.UseRouting as described in the msdn article.

` if (Configuration["Assessments:IngressPath"].Length > 0)
{
logger.LogCritical($"SETTING PathBase to {Configuration["Assessments:IngressPath"]}");
app.UsePathBase(Configuration["Assessments:IngressPath"]);
}

app.UseRouting();
`
I can tell that the call to UsePathBase is happening when running in kube because I can see my log entries being written.

'crit: Netalytics.Assessments.Frontend.Startup[0]
SETTING PathBase to /assessments
'
Unfortunately, when I go to the page it's still looking for the dotvvm--internal script without taking the path into account.
Its like UsePathBase didnt really affect it.

Thanks for the info, I'll try to reproduce it on my cluster.

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