Can't serve from a subpath

Description

The helm-dashboard seems to only respond on a / context.

I want helm-dashboard to respond from my.domain.com/helm-dashboard.

Additional information

As stated in the ingress-nginx documentation, I deployed helm-dashboard like this :

helm upgrade \
--install \
-n helm-dashboard \
--create-namespace \
helm-dashboard komodorio/helm-dashboard \
--set ingress.enabled=true \
--set ingress.className=nginx \
--set ingress.hosts[0].host=my.domain.com \
--set ingress.hosts[0].paths[0].path="/helm-dashboard(/|$)(.*)" \
--set ingress.hosts[0].paths[0].pathType=ImplementationSpecific \
--set "ingress.annotations.nginx\\.ingress\\.kubernetes\\.io/use-regex"=\"true\" \
--set "ingress.annotations.nginx\\.ingress\\.kubernetes\\.io/rewrite-target"=/\$2 \
--set dashboard.persistence.storageClass=proxmox-data

Here is the result of the Ingress object deployed :

Subsequently, I would like to set up oauth2 authentification.

I acknowledge the problem. But I lack advanced ReactJS skills to make it work with subpath correctly. Some external help is needed here.

It is absolutely not my domain either, but I found this issue where there are a lot of comments about this feature : https://github.com/storybookjs/storybook/issues/1291

I hope that could help.

As helm-dashboard is built in a / context, it's difficult, in a multipaths context, to rewrite the / routes from helm-dashboard to a dedicated subpath (as / matches all the apps under it).

However, if helm-dashboard is built in a default /helm-dashboard context (or something else), it would be a lot easier to rewrite the /helm-dashboard routes to another dedicated subpath.

I know my idea is a big change, but can it be a possible solution ?

I understand your idea, but it's same effort as making it work from subdirectory IMO. I'd prefer to keep it elegant.
